Which component of blood is responsible for transporting nutrients and waste through the body?

Plasma is a crucial component of blood that acts as the medium for transporting nutrients, waste products, hormones, and other substances throughout the body. It makes up about 55% of total blood volume and is primarily composed of water, but it also contains proteins, electrolytes, and nutrients. The water in plasma allows it to flow easily, carrying dissolved substances to cells and tissues that require them while simultaneously collecting waste products to be eliminated from the body.

Red blood cells primarily function to transport oxygen from the lungs to the tissues and carbon dioxide from the tissues back to the lungs for exhalation. White blood cells play an essential role in the immune response, helping to defend the body against infections. Platelets are integral to the clotting process, aiding in the repair of damaged blood vessels. While all these components are vital for the overall functioning of the circulatory system, it is plasma that specifically facilitates the movement of nutrients and waste throughout the body.
