Immunity
Immunity ( 54 Questions)
Directly attacking and killing infected cells is the role of cytotoxic T cells during cell-mediated immunity, but it is not the primary purpose of the overall immune response.
Antigens are foreign substances that trigger the immune response. They are not produced by the immune response itself but rather recognized by immune cells and antibodies.
The immune response is not involved in regulating the body's metabolism. Metabolism regulation is primarily controlled by other systems in the body, such as the endocrine system.
The immune response is a complex system of defense mechanisms that aim to protect the body from pathogens, such as bacteria, viruses, and other foreign substances. It involves the activation of various immune cells, production of antibodies, and other immune components to recognize and eliminate the invading pathogens.
