The part of the immune system that cleans up damaged cells is called:

Correct option is C

Ans: (c) Complement system Sol. The complement system is part of the immune system that helps clear damaged cells, microbes, and other pathogens from the body. It is a group of proteins that work together to enhance the ability of antibodies and phagocytic cells to clear out infections, damaged cells, and pathogens. The complement system also aids in inflammation and immune response regulation.
Explanation of each option:
· (a) Excretory system: The excretory system is responsible for eliminating waste products from the body, such as urine, but it is not directly involved in cleaning up damaged cells from the immune system's perspective.
· (b) Digestive system: The digestive system processes food for nutrients and eliminates waste, but it does not specifically focus on clearing damaged cells from the body.
· (c) Complement system: Correct answer. The complement system plays a crucial role in cleaning up damaged cells, as it enhances immune responses and promotes the removal of pathogens and dead cells.
· (d) Cell-based immune system: The cell-based immune system, including T-cells, B-cells, and phagocytes, helps defend the body against infections, but the complement system is specifically responsible for clearing dead cells and pathogens from the system.
