Blood- Components and Functions

Erythrocytes are also known as red blood cells which carry oxygen to the body and collect carbon dioxide from the body by the use of hemoglobin and its life span of 120 days. along the side the leucocytes helps in protecting the healthy cells because the W.B.C (leucocytes) act as the defending cells in protecting the immune system from the foreign cells. These leucocytes are multipotent cells in bone marrow and there life span is of 3-4 days where the yellow blood cells are called as thrombocytes they are where small and irregular in shape they have life span of 5-9 days they are mostly seen in mammals they help in clotting of blood which are in fibrin form called as thrombosis these lead to heart stroke, blockage of blood in blood mostly in arms and legs. where C.B.C is known as complete blood count is done to know the number of cells in a body these are mainly done by lab technician presently they are been tested by automatic analyzer the high and low amount of cells will lead to many diseases. Decrease of R.B.C  in the body these causes of anemia which leads to weakness, feeling of tired, shortness of breath and person will be noticeably pale. Formation of blood cellular components are called as Hematopoiesis and all the cellular blood components are derived from hematopoiesis stem cells in a healthy individual nearly 10¹¹–10¹²  new blood cells are produced these help in steady peripheral circulation. If there is a increases of R.B.C in the body these causes polycythemia these can be measured through hematocrit level.
