What is plasma?

Plasma is indeed the liquid portion of blood that plays a crucial role in carrying nutrients, hormones, proteins, and waste products throughout the body. It makes up about 55% of total blood volume and provides a medium in which various cellular components, like red blood cells, white blood cells, and platelets, are suspended. This fluid not only facilitates the transport of essential substances but also helps maintain blood pressure and regulates body temperature. In terms of its composition, plasma contains water, electrolytes, proteins (including albumin and globulins), and other substances that are vital for physiological functions.
