Which body system is responsible for producing red and white blood cells in bone marrow?
A
Endocrine system
B
Skeletal system
C
Integumentary system
D
Nervous system
Verified step by step guidance1
Understand that the production of red and white blood cells occurs in the bone marrow, which is found inside certain bones.
Recall that the skeletal system includes all the bones in the body, and the bone marrow within these bones is responsible for hematopoiesis (the formation of blood cells).
Recognize that the endocrine system involves hormone secretion, the integumentary system includes skin and related structures, and the nervous system controls body functions via nerve signals, none of which directly produce blood cells.
Identify that the skeletal system's role extends beyond structural support to include the production of blood cells in the bone marrow.
Conclude that the correct body system responsible for producing red and white blood cells in bone marrow is the skeletal system.
