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.

Answer:
Blood, fluid that transports oxygen and nutrients to the cells and carries away carbon dioxide and other waste products. It is a tissue because it is a collection of similar specialized cells that serve particular functions. These cells are suspended in a liquid matrix (plasma), which makes the blood a fluid.
