Understanding Blood and Its Components

The video explains the vital role of blood in the body, highlighting its components: red blood cells, white blood cells, platelets, and plasma. Red blood cells, or erythrocytes, transport oxygen and nutrients, while white blood cells, or leukocytes, fight infections. Platelets help in clotting and healing, and plasma carries these components, regulating bleeding and clotting. The video emphasizes the importance of each component in maintaining health and body function.
