thermophile.
ascospore.
3.
Vasoconstriction of skin arterioles when cold:
Increases heat loss by radiation
Reduces blood flow to the skin surface, reducing heat loss
Causes sweating
Raises metabolic rate
4.
Which statement best describes Thermoregulation?
Narrowing of arterioles supplying skin capillaries, reducing blood flow near the skin surface.
The maintenance of a relatively constant core body temperature.
Filtration of blood under high pressure in the glomerulus, forcing small molecules into Bowman's capsule.
The functional unit of the kidney, where blood is filtered and urine formed.
5.
Skin works with the circulatory and nervous systems in homeostasis. True or false?
False
True
False, it works alone
True only in cold
