Blood is one of the essential components within the human body. It keeps us ticking, moving, and pretty much keeps us alive. While most of us see blood as some red gooey liquid that comes out of our wounds, there are actually a number of components within our blood.These components are the plasma and the blood cells.
There are three types of blood cellswhich can be found within one’s blood --- the red blood cells, the white blood cells and the platelets. Plasma, the other component of a person’s blood, is the mixture of water, sugar, fat protein, potassium and calcium salts. Aside from these, plasma also contains several chemicals that enable blood to clot which is important to stop bleeding.
The red blood cells contain hemoglobin. Hemoglobin is the component that actually gives blood its red color. The red blood cells play an important part in our respiratory system. The red blood cellsmake sure thatthe oxygen that we inhale is carried all throughout our body. It then returns the oxygen as carbon dioxide back to the lungs for us to exhale.
The white blood cells on the other hand are cells that are clearer andbigger in sizered blood cells. The white blood cells are the ones that contain the important antibodies that allow our body to fight off any threats of infections, due to viruses, foreign proteins and several kinds of bacteria.
Platelets are not actual cells but mere fragments of cells. Along with the plasma, the platelets stop bleeding whenever we are wounded. Platelets gather around the edges of the wound whenever the body is injured and kicks off the process of healing by releasing chemicals that initiate clotting and the stoppage of bleeding.
