Blood is composed of four main components: red blood cells, white blood cells, platelets, and plasma. Red blood cells (RBCs) carry oxygen from the lungs to the rest of the body and return carbon dioxide to the lungs for exhalation. White blood cells (WBCs) are part of the immune system, helping fight infections and diseases.

Composition of Blood PPT: RBC, WBC, Platelets, Plasma
Platelets are responsible for blood clotting, preventing excessive bleeding when injuries occur. Plasma, the liquid portion of blood, makes up about 55% of its volume and carries nutrients, hormones, and waste products. Together, these components work to maintain overall health and body function.
