What is one function of plasma?

• A. Carries nutrients, vitamins, minerals and hormones
• B. Pumps blood
• C. Clots blood
• D. Produces red blood cells

Answer: (A)

Plasma acts as the liquid transport system of the blood, carrying dissolved substances around the body. It is mostly water, making it the medium in which nutrients, vitamins, minerals and hormones travel from where they’re absorbed or produced to the tissues that need them. It also helps move waste products to the organs that will process or excrete them. Because of this transporting role, describing plasma as carrying nutrients, vitamins, minerals and hormones best captures its main function. Pumping blood is done by the heart, not plasma. Producing red blood cells happens in the bone marrow. While plasma contains clotting factors that help blood to clot, clotting is a function of platelets and the coagulation cascade, not the primary job of plasma.
