Question

at which site does hematopoiesis occur? a) bone marrow b) periosteum c) liver d) cartilage e) capillaries

Explanation:

Hematopoiesis, the formation of blood cellular components, mainly occurs in the bone marrow in adults. The periosteum is a membrane covering bones and not involved in hematopoiesis. The liver is involved in fetal hematopoiesis but not the main site in adults. Cartilage is a connective - tissue and not related to blood - cell formation. Capillaries are blood vessels and not sites of hematopoiesis.

Answer:

A. Bone marrow
