What are the main components of blood?

Blood is a vital fluid that plays a crucial role in the functioning of the human body. Composed of various elements, the main components of blood are red blood cells, white blood cells, platelets, and plasma. Red blood cells, shaped like biconcave discs, carry oxygen from the lungs to different organs and tissues and transport carbon dioxide back to the lungs for elimination. White blood cells are an integral part of the immune system that helps defend the body against pathogens and infections. Platelets aid in blood clotting, preventing excessive bleeding when injuries occur. Finally, plasma, a yellowish fluid, serves as the carrier for all blood cells, hormones, waste products, and nutrients throughout the body, maintaining the overall balance and homeostasis.
