Blood

Blood is a continually flowing fluid that provides nourishment, oxygen, and waste elimination to the body. Blood is essentially liquid, yet it contains countless cells and proteins that make it “thicker” than pure water. The typical person’s blood volume is roughly 5 litres. Plasma is a liquid that makes up around half of blood. Plasma is made up of proteins that aid in blood clotting, the movement of chemicals through the bloodstream, and other processes.
