Answer:

The main components of plasma are water, proteins, electrolytes, hormones, and waste products.

Plasma is the fluid portion of the blood that makes up about 55% of the total blood volume. It is a vital component that carries nutrients, gases, hormones, and waste products throughout the body. The main components of plasma include water, proteins, electrolytes, hormones, and waste products.

Water in plasma helps maintain blood volume, while proteins play a crucial role in clotting, immune defense, and transport of substances. Electrolytes such as sodium, potassium, and calcium are essential for nerve function and muscle contraction. Hormones carried by plasma regulate various processes in the body, and waste products are transported to organs like the kidneys for excretion.

Understanding the composition of plasma is crucial for maintaining overall health and ensuring proper bodily functions.
