Blood: The Trucking Company of the Body

By Verhonda Wiltz

I know, you have never thought about your body in this way. Most of us don’t know how our body works or even care…. Until it stops working as it should!  Most of the time, when it’s not working at its best, it’s hard to get it repaired and back on track. So, it’s best to maintain it and keep it in good shape. In order to do that, you need to understand how it works.  Let’s start now with your blood.

Blood is the trucking company of your body. Think of it as a fleet of trucks and trailers. The blood cell is the truck/tractor, and the iron that is attached to the cell is the trailer.  It carries fuel, gases and other chemicals to your whole body and removes wastes from your body too. Blood travels along a superhighway of blood vessels called arteries, mainly used for deliveries, and veins for pickup.  There are also streets off the highway called arterioles and capillaries. Your body has over 60,000 miles of highway inside you.

The main business office for the blood trucking company is in the bone marrow. Bone marrow is deep in the center of your bones.  This is where your blood is made and released/dispatched onto the highway. 

The kidneys are the truck wash for the blood/truck. They clean the blood of all wastes and inspect and work with the spleen on removing old worn out blood cells/trucks from the highway. When it’s time to replace the blood cells/trucks, the kidneys dispatch a message to the bones/business office and new blood cells/trucks are released on the highway.

The spleen is the blood recycling center for old, worn out blood cells.  The spleen has a highway maintenance crew that repairs the highway when it gets holes, burns and scrapes in it. The highway must be kept smooth at all times to prevent traffic jams and multi-truck accidents. It also has a hazardous material crew that it sends out when infections occur. 

Now that you have the main operation procedure down, we will now follow a normal route of a red blood cell.  We will start with a new blood cell/truck.

Red Blood Cell with iron = Truck with Trailer

The first assignment for the blood cell is to take the highway from the bones to the lungs for oxygen/air.  Traffic should flow smoothly because the highway only flows in one direction.  The blood cell/truck must first pass through a highway roundabout exit called the heart that leads the blood cell/ truck to the lungs. When the blood cell reaches the lungs, it turns onto one of many of the veins/streets and loads the oxygen/air into its trailer. Then it leaves the lungs by turning onto the arterioles/streets, goes back to the highway roundabout entrance at the heart and begins its trip to deliver the oxygen/air to one of the many other cells and organs of the body.  These blood cells/trucks are very fast!  They do this in less than one minute when you are resting, and much faster if you are running or scared!  

The next stop is to deliver this oxygen/air to the digestive system organs. The food processing center! The first stop is to deliver the oxygen/air to the stomach cells. That really doesn’t take much time at all. Then it is sent to the liver/sorting warehouse of the body to pick up some fuel called glycogen and deliver it to the leg muscle cells.  The blood cell/truck passes through an inspection weight station before leaving the liver to be sure the truck is running well and can deliver the fuel. If it is running well, it will take the glycogen to the leg muscle cells.  Don’t forget that there are millions of these red blood cells/trucks on the highways of your body making deliveries and pickups all the time. They even work when you are sleeping!

Now the blood cell/truck has made it to the leg muscle cells and delivered the glycogen, it must pick up some waste/carbon dioxide.  There are other types of waste that your body makes, but for the sake of time, we will take the carbon dioxide and deliver it to the lungs to be dumped outside the body. The blood cell/truck gets back on the highway and follows it south until it turns onto the veins and then heads north back to the heart.  It makes its exit at the highway roundabout again inside the heart, to the arterioles and delivers its load of carbon dioxide to the lungs where it is pushed out of the lungs, through the nose into the air.  

Every so often  it makes a delivery to the kidneys for waste dumping and gets an inspection at the spleen for best highway function. 

If it doesn’t pass inspection, usually every 20 days, it gets removed from the highway and sent to the spleen for recycling. 

Remember when I mentioned that the highway had to be kept smooth and the spleen was in charge of the maintenance crew? We are now going to talk about that maintenance team/crew.

The team consists of white blood cells, red blood cells and platelets-small round shield shaped cells. This team patrols the highway and the streets to keep them smooth. If they find an area that needs repairing, they close the damaged area off and narrow the area while they work.  The white blood cells clean the area of dirt, germs and anything that is not a red blood cell, white blood cell or platelet. Some red blood cells bring fibrinogen, a special chemical that combines with the platelets to make a patch.  The team stays there until the patch is dry. Then the crew moves down the highway where they are needed next. 

Now we will get to the big part about this trucking company.  What do you have to do to keep this company going? How do you keep your fleet of trucks at their best?

This company needs lots of water! It keeps the highway smooth and free of traffic jams, and the kidneys need water to wash the trucks inside and out.

Kidneys = Truck wash

Water is also needed for highway and street repairs.  So start by drinking lots of water every day. 

It is also important to eat foods with lots of iron. Spinach, collard, turnip, mustard greens, broccoli, fish, nuts, grapes, raisins, eggs and some red meat- beef, pork, lamb, chicken, sweet potatoes, turkey, quinoa and oats to name a few. You must remember that these foods are great, but you cannot eat them with cheese or drink tea or milk while you eat them. The iron washes out of your body if you do.

Sleep is when most of the inspections and repairs happen, so allow enough time for these processes to be done.  Exercise keeps the blood cells/trucks moving on the highway and prevents traffic jams and accidents. It’s important to keep moving! 

Now that you know about your blood, the trucking company of your body, it’s time to get it in top shape!

What is the Smartest Animal on Planet Earth?

My tablet, my tablet can you recall, what animal is the smartest one of all?

We tend to think of humans as being the most intelligent of all in the animal

kingdom, but there are others that are just as smart. We always hear about

the chimpanzees and the rats, but what about the other animals? 

Some animals live in the ocean, some fly in the air, and some walk with us

across the land… just what is animal intelligence? According to

Zooportraits.com:

We can define animal intelligence as the combination of skills and abilities that allow animals to live in and adapt to their specific environments.

They have found ways to change their habits and behaviors to adapt to the

Earth changes for millions of years!

Some animal species have been forming social groups long before humans

discovered Facebook, Instagram and other social media. Let’s look at a few

of the smartest animals on Earth!

Octopuses

The world’s smartest invertebrates, animals without skeletons, are

octopuses.

Octopuses should be smart…. They have eight legs and NINE brains!!! They

have more to work with than most of the other animals. Octopuses can

protect themselves by pretending to be other animals. They have also l

earned to use tools to survive. 

Octopuses can carry out complex tasks, such as opening a jar to get to its contents. Not only do they have a good short and long term memory but also a remarkable ability to learn new skills from the moment they’re born. For example, the mimic octopus (Thaumoctopus mimicus) is able toimpersonate other species in order to protect itself from predators. Well, at least a female giant Pacific octopus named Billye can. Biologists at the Seattle Aquarium put Billye’s strength and smarts to the test with a bottle-opening challenge. The clever cephalopod was able to unlock the top and access her snack in five minutes. Perhaps that’s unsurprising for a creature known to open clam shells and other stubborn-shelled mollusks without a shucking knife. [The 5 Smartest Non-Primates on the Planet] Yes, like chimpanzees, dolphins and crows, octopuses are among the special set of intelligent animals that have been observed using tools. In 2009, scientists reported they had watched veined octopuses (Amphioctopus marginatus) picking up discarded coconut shells and using them like mobile homes.

Whales and Dolphins

The largest brained animals of the ocean are the whales and dolphins. They

are also considered some of the smartest oceanic animals alive.

Whales and dolphins have large brains; brainy dolphins have a brain to

body ratio second only to humans. Large-brained creatures generally have

a few things in common: they live long lives; 

they are sociable; their behaviour is complicated

Elephants

The largest brained animals on land are elephants. I know you have heard

that an elephant never forgets! There are other things elephants can do too!

Elephants are large animals with big brains. They are considered smart for several reasons: they break off sticks with their trunks, have incredible memories, and seem to be capable of empathy.  Elephants also work together to solve puzzles, according to researcher Joshua Plotnik from the University of Cambridge in England. In one experiment, two elephants had to drag ropes attached on either side to a table holding two food bowls. This required cooperation because only one elephant pulling wasn’t enough. 

Ducks, Parrots, Ravens and Crows

Now let’s look at some of our friends that fly! They have to be smart also, so

they don’t get lost. The sky is large you know!

This isn’t some quack of an inclusion. Ducklings imprint on their mothers, but scientists were curious about how the ducklings managed to differentiate between imprinted beings and non-imprinted. They put ducklings in an enclosure and trailed two different pairs of objects around on strings, one matching pair of shapes (like two spheres) and one pair of non-matching shapes (like a cylinder and a cube). After the duckling showed a tendency toward set, the researchers put the ducklings in a different enclosure with different matching and non-matching pairs. The ducklings would follow after whatever set best resembled their original imprint. So, if they followed the two spheres in the first enclosure, they would follow a set of matching cubes in the second enclosure. This tendency, according to researchers interviewed by the Christian Science Monitor, has only been seen in primates, crows and parrots before, indicating that ducks may be smarter than we’ve thought.

We all know parrots can reproduce sounds of the English language (or other languages). But some even have an understanding of the meaning of these words.   The most impressive example of this ability is Alex, an African Grey parrot, who knew colors and shapes and learned more than 100 English words. He was trained by Irene Pepperberg, a comparative psychologist at Brandeis University and Harvard.  Before Pepperberg’s groundbreaking work with Alex, “scientists had little expectation that any bird could learn to communicate with humans,” the New York Times wrote in 2007, following Alex’s death.

Ravens are more than the subject of dark themes by writer Edgar Allan Poe. They are also extremely resourceful animals that have been known to multi-task. Researchers from Canada and Scotland have shown that ravens use logic to understand their surroundings in a way that may surpass the ability of the great apes. The crow, a close cousin to the raven, is also an extremely smart bird.

Morell notes in an article for National Geographic: “New Caledonian crows are among the most skilled of tool-making and tool-using birds, forming probes and hooks from sticks and leaf stems to poke into the crowns of the palm trees.”

Pigs

This gives you a whole different way of looking at these animals! Would you

care to play a game against a pig?

Pigs are highly adaptable mammals with a keen ability to learn new skills. In fact, some studies suggest that an adult pig may have a level of intelligence comparable to that of a three year old child! This would make them far smarter than other domestic animals, such as dogs and cats.

The New York Times reports on researchers who have found that domestic pigs can use mirrors to find their food, and will try to deceive other pigs so they can “hog” more food. They also learn quickly and can do tricks ranging from jumping through hoops to playing video games with joysticks.

Bees

Entomologists, scientists who study insects, have been studying bees for

hundreds of years have found that most hives are 95% female bees! 

“These are, high, high, highly intelligent creatures,” said conservation biologist Reese Halter.1   Halter was speaking of the fascinating bee. Bees are already famous regarding their ability to communicate with other bees through complex dancing routines. Halter’s team also found that bees have puzzle-solving abilities. In 2006, scientists were amazed to discover that bees have a biological clock. They described it as, “An endogenous, physiological mechanism, whose exact nature has not been determined, that keeps time independently of external events.”It is actually more similar to humans than to insects. 

Bees continue to astound scientists when tested for cognitive abilities in the lab.  For example, the bees can learn to slide or lift caps, then subsequently push balls of escalating weight to access the reward. When the researchers put the bees who knew how to solve the puzzle in a hive with naïve bees, they somehow went on to communicate the solution to their unlearned kinfolk.6   Entomologists recently discovered that bees have a capacity to discriminate numbers. “Honeybees can identify a piece of paper with zero dots as ‘less than’ a paper with a few dots.”7 It has always been assumed that what separates man from the animal world (among other things) is an understanding of the abstract concept of “zero.” But Howard and his team have now shown that untrained honey bees have an understanding of an “empty set.” The authors stated, “Bees demonstrated an understanding that parallels animals such as the African grey parrot, nonhuman primates, and even preschool children.”    Loukola and his team concluded that the learning ability of bees is extraordinary. Such unprecedented cognitive flexibility hints that entirely novel behaviors could emerge relatively swiftly in species whose lifestyle demands advanced learning abilities, should relevant ecological pressures arise.8

What an example of Girl Power!

Dogs

We can’t forget some of our best friends!

“In many ways dogs may be more human-like than any other species, even non-human primates,” researchers wrote in a 2008 dog intelligence study published in the Journal of the Experimental Analysis of Behavior. In a separate study, Brian Hare, an expert in canine cognition, showed that dogs can follow and respond to human gestures, like pointing and eye movements, without training. This so-called “theory of mind” ability “is so important to our species,” writes Slate’s David Grimm, “that without it, we would have trouble learning and interacting with the world around us.”   One the smartest dogs in the world (or at least with the most impressive vocabulary) is a border collie named Rico. Rico knows the name to more than 200 items — he can retrieve the object from a jumble of stuff after hearing the name only once. (Rico also took third prize in De Waal’s “Animal Noble Prizes”) Another dog, Chaser, knows more than 1,000 objects and can understand English grammar. She isn’t the first animal to have a basic understanding of grammar. Studies published in the journal Cognition in 1984 indicated that dolphins can also grasp elements of grammar. 

So maybe this is why they are used as service animals for us.

My tablet, my tablet now sitting on my lap,

Thank you my tablet with your Internet and Google too! 

Now we can be a little smarter than we were when we started!

 We can name other smart animals on the land, in the air and in the oceans

and learn more about them as we grow.

 This has been some good information to begin to know!
