Question

Which one of the following statements is true for both macrophages and neutrophils?

1) They are both types of white blood cells.
2) They are both involved in the immune response.
3) They are both phagocytic cells.
4) They are both found in the bone marrow.

Answer 1

Both macrophages and neutrophils are phagocytic cells that partake in the immune response, with neutrophils acting as rapid responders and macrophages serving as both scavengers and activators of the adaptive immune response.

Step-by-step explanation:

The correct statement that is true for both macrophages and neutrophils is that they are both phagocytic cells. Neutrophils are a type of white blood cell classified as granulocytes, containing cytoplasmic granules and exhibiting a multilobed nucleus. They rapidly respond to sites of infection and are known for their phagocytic capabilities, engulfing and digesting pathogens. Macrophages, on the other hand, arise from monocytes and are classified as agranulocytes. They are large phagocytic leukocytes with a more prominent role in both the innate and adaptive immune responses, acting as scavengers in tissues and also as antigen-presenting cells that can activate other immune cells. Both neutrophils and macrophages can be found in the bloodstream and tissues and are critical in defending the body against infections.
