Problem: During granulopoiesis, roughly half of the neutrophils produced will enter into circulating pool, while the other half will remain in the marginating pool. Which of the following best describes the difference between the circulating and marginating granulocyte pools? The circulating pool contains immature granulocytes, while the marginating pool consists only of mature granulocytes. Neutrophils in the circulating pool move freely in the bloodstream, while those in the marginating pool adhere to the vessel walls in spaces such as the liver and spleen, ready to respond to inflammation or infection. The marginating pool consists of granulocytes in the lymphatic system, and the circulating pool includes granulocytes in the spleen and liver. The circulating pool consists of neutrophils stored in the bone marrow, while the marginating pool is the total number of neutrophils in circulation. Need Assignment Help?
