What two medical terms are synonymous with immunosuppression?

Agranulocytosis and neutropenia are both terms used to describe a significant decrease in specific types of white blood cells—granulocytes, particularly neutrophils, which are critical components of the immune system. When an individual experiences either agranulocytosis or neutropenia, their immune response is compromised, making them more susceptible to infections and illnesses. This condition aligns with the concept of immunosuppression, where the body's ability to fight infections is weakened.

Leukopenia, as mentioned in the first choice, refers to a reduced white blood cell count in general, but it is not specific to the types of cells crucial for combating infections. Thrombocytopenia refers to low platelet levels, which does not pertain to the immune response directly. Hypotension, the state of abnormally low blood pressure, and its association with infection does not specifically indicate immunosuppression either. Thus, agranulocytosis and neutropenia clearly describe conditions where the body's immune defenses are compromised, making this the correct answer.
