The Importance of Blood and Blood Cells
The heart is responsible for pumping blood throughout the body.
Typically, the body contains around 10 pints of blood, which is circulated throughout the body by the heart.
In an average adult, all 10 pints are circulated one time per minute, however during exercise this can increase to up to 4 times per minute.
The Different Types of Blood Cells
About half of all a human’s blood consists of blood cells, with the other half consisting of plasma. There are three categories of blood cells: red blood cells, white blood cells, and platelets.
The red blood cells, which are the most common type of blood cell, are used to exchange oxygen and carbon dioxide. This type of blood cells looks much like a doughnut and contains hemoglobin. Hemoglobin is an iron containing molecule that is able to quickly and easily bind with oxygen when there is a high concentration, such as in the lungs, and release oxygen when there is a low concentration, as is found in the other areas of the body. In this manner, the red blood cells absorb oxygen in the lungs and transport it to other parts of the body.
The body's white blood cells can be divided into several categories, but they all are used to fight disease and infection. Some will actively seek out and attempt to surround bacteria, while others release antibodies to help remove and prevent specific types of disease, such as the measles.
Platelets are the smallest type of blood cell and help form blood clots. Within seconds after a cut, the platelets kick into action to form a sort of plug to prevent blood loss.
Plasma is fluid like and is basically everything that is left over in the blood stream, once you remove the white blood cells, red blood cells, and platelets. It consists of 95 percent water and has a salt content that is similar to that of salt water.
