10 Interesting Facts about Blood

Plasma makes up more than half of the fluid in blood

The following 10 interesting facts about blood are just a few of the fascinating aspects of this specialized bodily fluid. This subject is endlessly fascinating for people who study medicine, particularly those who specialize in hematology. Here are a few of those interesting facts:

1. Blood delivers oxygen, nutrients and other vital matter to cells in the bodies of humans and other animals.

2. Blood transports waste products from the same cells that it delivers oxygen, nutrients and other vital matter to.

3. Blood vessels move the blood throughout the body, facilitated by the heart’s pumping mechanism.

4. Blood carries carbon dioxide back from those tissues to the lungs through the human body’s veins. Technically, it is a waste product of the cellular metabolism—but it is certainly not something we could live without!

5. Blood carries oxygen from the air inhaled into human lungs to various tissues throughout the body through a network of arteries.

6. Humans and other jawed vertebrates rely on white blood cells to maintain an adaptive immune system (resistance to parasites and infections).

7. Red blood cells are composed of protein called hemoglobin that contains a rich amount of iron and helps move oxygen throughout the body, which gives blood its red color in humans and other vertebrates.

8. The blood of humans and other vertebrate animals is composed of cells encased in a liquid called plasma, which makes up more than half of the fluid in blood.

Plasma is composed of mostly water, but it also consists of a necessary amount of carbon dioxide, dissipated proteins, glucose, hormones, mineral ions and platelets. 9. The majority of human blood cells are white blood cells, which include platelets, leukocytes, and red blood cells, which are the most copious.

10. The platelets in white blood cells are what help blood clot, which is particularly important when a person has a wound.

There are many terms that are used to discuss blood and its academic or scientific study. Most of them begin with the word hemo or hemato, such as hematology, which means “the study of blood.” All you really need to know about blood is that we can’t live without it. Humans, animals and even invertebrates have their own special blood systems, and we rely on it to keep us moving, breathing and doing everything else we need to do. As you consider these interesting facts about blood, just remember that none of us would be anywhere if it wasn’t for our blood!
