What bodily fluid helps protect from infection and bacteria?

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

Answer: (C)

Blood plays a vital role in the immune response and helps protect the body from infection and bacteria. It is a complex fluid that circulates throughout the body, transporting essential components such as red blood cells, white blood cells, and platelets. White blood cells, or leukocytes, are a key part of the immune system and are critical for defending against infections. They identify and destroy pathogens, including bacteria and viruses. Additionally, blood contains antibodies that specifically target and neutralize harmful microorganisms as part of the adaptive immune response. While plasma and serum are components of blood, they primarily serve as mediums for transporting nutrients, hormones, and waste products, and do not play as direct a role in the immune response. Lymph, on the other hand, is involved in immune function and fluid balance but is distinct from blood itself. Blood, as a whole, encompasses various protective mechanisms and is essential for maintaining overall health and combating infections.
