-Diffusion transports nutrients from blood vessels in the dermis into the epidermis.
-Solute pumping transports nutrients into the epidermis. Diffusion transports nutrients from blood vessels in the dermis into the epidermis.
Which of the following describes the effector response of sweat glands and blood vessels?
-Sweat glands stop releasing sweat and blood vessels constrict.
-Sweat glands stop releasing sweat and blood vessels dilate.
-Sweat glands release sweat and blood vessels constrict.
-Sweat glands release sweat and blood vessels dilate. Sweat glands release sweat and blood vessels dilate.
What is the role of the cutaneous membrane in thermoregulation when body temperature is elevated?
-Sweat glands are thermoreceptors that release sweat when body temperature is elevated.
-Blood vessels act as effectors and undergo vasodilation when body temperature is elevated.
-The thermoreceptors can directly stimulate sweat glands to release sweat and remove excess heat from the body.
-The thermoreceptors contact the blood vessels and cause vasoconstriction in order to lower body temperature. Blood vessels act as effectors and undergo vasodilation when body temperature is elevated.
