Immune system is a system of specialized cells and organs that protects the body from foreign substances, such as bacteria and viruses. The immune system is the body's natural defense against infection and disease. It is made up of a network of organs, tissues, and cells that work together to protect the body from harmful invaders. The immune system is divided into two main parts: the innate immune system and the adaptive immune system. A. The correct answer is "Functions to specifically inhibit cyclooxygenase-2 (COX-2) to decrease pain and inflammation." Corticosteroids, such as dexamethasone, can have a profound effect on the imAine system, which in turn can lead to decreased pain and inflammation. By specifically inhibiting cyclooxygenase-2, corticosteroids can decrease the production of prostaglandins, which are compounds that play a major role in pain and inflammation. Thus, by decreasing the production of prostaglandins, corticosteroids can decrease pain and inflammation. B. Intermediate events of innate immune system inflammation refers to the events that take place between the initial response and the resolution of the response. The main event during this stage is the secretion of cytokines by immune cells. Cytokines are small proteins that coordinate and regulate the immune response. They help to activate other cells and promote healing. One such cytokine is interleukin 2, which regulates the growth and differentiation of T cells. The secretion of IL-2 by immune cells is specific to the intermediate stage of innate immune system inflammation. The correct answer is A.
