Blood is a bodily fluid in animals that delivers necessary substances such as nutrients and oxygen to the cells and transports metabolic waste products away from those same cells. The components of blood include plasma (the liquid portion, which contains water, proteins, salts, lipids, and
glucose), red blood cells and white blood cells, and cell fragments called platelets. -
It is a specialized bodily fluid that supplies essential substances and nutrients, such as sugar, oxygen, and hormones to our cells, and carries waste away from those cells. This waste is eventually flushed out of the body in urine, feces, sweat, and lungs (carbon dioxide). Blood also contains clotting agents.
