In fact, blood volume consists of two parts: plasma volume and blood cells, and most of the plasma is water, including proteins and low-molecular substances in addition to water. Plasma can effectively maintain the colloidal osmotic pressure of the body, and can also effectively regulate the water distribution inside and outside the cell; Blood cells are divided into three main categories: red blood cells, white blood cells, and platelets.

    Red blood cells are the most important component of blood cells, and red blood cells also contain hemoglobin, which plays a vital role in blood transportation.
