When reviewing the musculoskeletal system, the nurse should recall that hematopoiesis takes place where?

A) Liver
B) Spleen
C) Kidneys
D) Bone marrow

The musculoskeletal system functions to encase and protect the inner vital organs, to support the body, to produce red blood cells (hematopoiesis) in the bone marrow, and to store minerals. The other options are not correct. The liver has many functions such as detoxifying the blood, production of bile, and synthesis of proteins needed for blood to clot, but hematopoiesis is not one of its functions. The spleen has many functions such as filtering the blood as part of the immune system, recycling old red blood cells, and storing platelets and white bloods cells but it is not the location of hematopoiesis. The kidney also has many functions such as maintaining fluid balance, filtering minerals, and production of hormones that help stimulate red blood cells production; however, it is not the location of hematopoiesis.
