Which component of blood is responsible for transporting nutrients?

Plasma is the component of blood responsible for transporting nutrients throughout the body. It is a yellowish liquid portion that makes up about 55% of total blood volume and consists mostly of water, in which various substances are dissolved. This includes nutrients such as glucose, amino acids, hormones, and electrolytes, allowing these essential compounds to be easily transported to tissues and organs where they are needed for metabolic processes.

In addition to nutrients, plasma helps carry waste products, carbon dioxide, antibodies, and proteins, contributing to overall homeostasis and protection. The presence of nutrients in the plasma is crucial for providing energy and building blocks for cells, which maintain the body’s cellular functions. The other blood components play different roles; for instance, red blood cells are primarily involved in oxygen transport, while white blood cells are part of the immune system, and platelets play a critical role in blood clotting.
