I’m going to do my best to describe the composition of blood and what each part of the blood does, but as I have no former science knowledge, I have had a hard time understanding all of the information presented, but I will do my best to make sense of it.
There are four main parts that compose the blood. They are as follows: Red Blood Cells; White Blood Cells; Plasma; and Platelets.
Red blood cells are probably the most well-known part of the blood. They are the cells that carry the oxygen to the other cells of the body so that they can function, and are what give the blood its red color. They are the main part of the blood.
There are a lot less white blood cells compared to the red cells, but they are important nonetheless. The white blood cells are what fight off infections and unwanted things that are in the blood, and they serve as a part of the body’s immune system.
The plasma is actually the liquid portion of the blood. It is made of mostly water, but it also contains other proteins and stuff that help the other cells in the body function.
Lastly, we have the platelets. They are cells that are there to help begin the healing process of injured tissue, by first creating a blood clot to stop leakage so that the cells can then begin to heal and the white blood cells can then fight off any foreign substances in the body.
