The colorless liquid, rich with white blood cells that attack bacteria in the blood is known as:

• A. Plasma
• B. Serum
• C. lymph
• D. Interstitium

Answer: (C)

The correct answer is lymph, which is a clear fluid that is a vital part of the body's immune system. Lymph contains a high concentration of white blood cells, particularly lymphocytes, which are crucial in the body’s defense against infections. These white blood cells actively seek out and attack bacteria and other pathogens, helping to maintain the overall health of the body. Plasma, the fluid component of blood, contains nutrients, hormones, and proteins but does not specifically refer to the colorless liquid rich in immune cells. Serum is derived from plasma after the blood has clotted and is mostly devoid of clotting factors; it contains antibodies and other proteins, but does not have the same immune response role as lymph. Interstitium refers to the space between cells in tissues, which is not primarily associated with the immune response or the specific function of attacking bacteria. Understanding these distinctions clarifies why lymph is the appropriate term for the clear liquid rich in white blood cells.
