The liquid portion of the blood without its cellular elements is known as ______.

• A. Plasma
• B. Serum
• C. Urine
• D. Lymph

Answer: (A)

The liquid portion of blood that remains after removing the cellular elements is plasma. Plasma is the watery matrix of blood, making up about 55% of blood volume, and it contains water, proteins (including albumin, globulins, and fibrinogen), electrolytes, nutrients, hormones, gases, and waste products. When blood is allowed to clot and the clot is removed, the liquid that remains is serum, which lacks clotting factors like fibrinogen. Urine is the filtrate produced by the kidneys, not a component of blood, and lymph is fluid from the lymphatic system. So the term for the liquid part of blood without its cells is plasma.
