What amazing substance is your own Blood!
In ancient times the people didn���t have the tools of the modern science but still they understood the importance of the blood and very often declared it SACRED SUSTANCE.
Today science have discovered so many aspects of the Blood that it is frustrating to read all that is posted even in the easy to read - popular articles on the internet.
It is even harder to sift through all this information and to learn only what is important and practical to know about your own blood.For this reason, I will try to summarize what is Blood.
The average human adult has a blood volume of about 5 liters (1.3 gal), composed of
1)Blood Plasma (54.3%)and
2)several kinds of cells (45.7%).
The formed elements (cells) of the blood are:
1.Red Blood Cells (RBC or Erythrocytes) ��� 45%,
2.Leukocytes (White Blood Cells) 0.7%, and
Red Blood Cells (RBC or Erythrocytes) ��� 45%,
The RBC-consist mainly of hemoglobin, a complex molecule containing heme groups whose iron atoms temporarily link to oxygen molecules in the lungs and release them throughout the body. Oxygen can easily diffuse through the red blood cell's cell membrane. Hemoglobin also carries some of the waste product carbon dioxide back from the tissues.
Leukocytes (White Blood Cells) 0.7%,
The White Blood Cells are part of the immune system; they destroy and remove old or aberrant cells and cellular debris, as well as attack infectious agents (pathogens) and foreign substances.
The Platelets are responsible for blood clotting (coagulation). They change fibrinogen into fibrin. This fibrin creates a mesh onto which red blood cells collect and clot, which then stops more blood from leaving the body and also helps to prevent bacteria from entering the body.
