Which hormone causes dilation of blood vessels, increased oxygen consumption and glycogenolysis?
ACTH
Insulin
Adrenalin
Adrenalin
C.
Adrenalin
Adrenaline (epinephrine) is a hormone produced by adrenal medulla and is secreted in great amounts during emotional states. It elevates the glucose level in blood stream (by glucogenesis) which is accompanied by an increase in oxygen consumption, body temperature, heat production. Adrenaline also causes an increase in the flow of blood by dilating the blood vessels.
Insulin regulates the glucose level in blood.
ACTH (Adreno Corticotropic Hormone) is secreted by the anterior pituitary and stimulates the adrenal cortex.
Glucagon is a polypeptide hormone secreted by the alpha cells of islets of langerhans of pancreas. It acts to promote glycogenolysis.
