The fluid found in the circulatory system of humans and other animals that delivers vital substances to the cells like oxygen molecules or nutrients while removing metabolic waste products away from cells is known as blood.
The blood is made up of blood cells suspended in plasma.
Blood corpuscles
Red blood cells (erythrocytes), white blood cells (leukocytes), and platelets are the three main types of blood cells (thrombocytes).
These three types of blood cells account for 45 percent of the volume of blood tissue, with plasma, the liquid component of blood, accounting for the remaining 55 percent.
