The liquid portion of the blood is called plasma.

A. True

B. False

The liquid part of blood is called plasma. It is a protein–salt solution composed of more than 90% water and makes up over half of the blood’s volume. Plasma appears as a light yellow fluid when separated from blood.

Plasma contains proteins, inorganic salts, nutrients, gases, hormones, enzymes, wastes, antibodies, and clotting factors. Its main function is to transport nutrients, hormones, and proteins to different parts of the body, while also carrying waste products from cells.

Plasma suspends blood cells (like white blood cells) and serves as the body’s transport system. It is formed largely from water and salts absorbed through the digestive tract. Plasma is used medically for treating many diseases and can be collected from healthy donors through plasmapheresis.
