5 5 5 5 5 5 5 5 5 5 5
responses, arise from red bone marrow?(intraepidermal macrophages) are
5 5 5 5 5 5 5 5
active in the immune response. help other immune cells recognize and
5 5 5 5 5 5 5 5 5 5 5
destroy a antigen. They are produced in bone marrow.

sexual excitement.

5They function in thermoregulation and emotional sweating. Note: glands
5 5 5 5 5 5 5 5 5
empty onto the skins surface.

stratum basale (germinativum) - Correct answer ✔-always undergoing
5 5 5 5 5 5 5 5
mitosis, pushing toward the surface
5 5 5 5
Vitamin D synthesis and activation - Correct answer ✔-Vitamin D is
5 5 5 5 5 5 5 5 5 5 5
synthesized in the skin in response to ultraviolet radiation and is also
5 5 5 5 5 5 5 5 5 5 5 5
absorbed from the diet. 5 5 5
-It is then transported to the liver, where it undergoes 25-hydroxylation. This
5 5 5 5 5 5 5 5 5 5 5 5
metabolite is the major circulating form of vitamin D.
5 5 5 5 5 5 5 5
-The final step in hormone activation, 1-hydroxylation, occurs in the kidney to

Formation of a fracture- hematoma begins 6-8 hours after injury when broken
5 5 5 5 5 5 5 5 5 5 5
blood vessels leak blood into the surrounding tissue and blood clotting
5 5 5 5 5 5 5 5 5 5 5 5
occurs. Swelling and inflammation occur. Phagocytic cells (neutrophils and
