A healthy human being will have approximately 5 liters of blood flowing through his body. Blood constitutes of main parts viz. blood cells and plasma. The blood cells are of three types:
- Red Blood Cells (RBC) - RBCs gives oxygen and take carbon di-oxide from body cells.
- White Blood Cells (WBC) - WBCs protect our body from infections caused by micro- organisms.
- Platelets - Platelets help us in preventing and stopping bleeding from cuts and wounds.
These blood cells float in plasma, which contains proteins, fats, minerals, vitamins and many essential elements and in short, all the nutrients required for the body cells to survive and function. Plasma is the transport medium for everything that passes from organ to organ, into and out of the body tissues.
