Blood:-
Blood is essential to life. Blood circulates through our body and delivers essential substances like oxygen and nutrients to the body’s cells. It also transports metabolic waste products away from those same cells. There is no substitute for blood. It cannot be made or manufactured. Generous blood donors are the only source of blood for patients in need of a blood transfusion.
The normal white cell count is usually between 4 × 109/L and 1.1 × 1010/L. In the US, this is usually expressed as 4,000 to 11,000 white blood cells per microliter of blood.
Blood is a red liquid which has various kinds of cells spended in it. It flows through our body.
The number of white blood cells in human body are between 4,000 to 10,000 cells per microlitre of blood.
