One cubic centimetre of blood is equal to one “cc” of blood. One millilitre is equal to one cubic centimetre. The average person’s blood volume is about 5,000 cubic centimetres.
Blood is a vital component of the human body because it transports nitrogen, oxygen, and other nutrients to the body’s vital organs. Plasma and blood cells are the two components of blood. Plasma contains proteins that help blood clot in the event of an injury. Blood cells make up about half of the volume of blood. White blood cells fight infections, and platelets aid in blood clotting. Red blood cells transport oxygen to tissues and organs, while white blood cells fight infections.
In the United States, the American Red Cross collects approximately 15.7 million blood donations each year. During the donation, approximately 1 pint (473 cubic centimetres) of blood is collected. One blood donation, according to the American Red Cross, can save up to three lives because red blood cells, platelets, and plasma can all be used separately from the blood.
