QuestionSBA
QuestionChoice
This is correct. Countercurrent exchange is a mechanism to conserve heat. Heat from warm blood in arteries travelling towards to skin is transferred to veins travelling back towards the trunk. This maintains the trunk temperature while preventing heat loss from the skin.

a
Transfer heat from arteries to adjacent veins
QuestionChoice
This is incorrect. Countercurrent exchange helps with heat conservation, not oxygen transfer. Heat from warm blood in arteries travelling towards to skin is transferred to veins travelling back towards the trunk. This maintains the trunk temperature while preventing heat loss from the skin.

c
Transfer oxygen from arteries to adjacent veins
QuestionChoice
This is incorrect. Countercurrent exchange helps with heat conservation, not blood pressure regulation. Heat from warm blood in arteries travelling towards to skin is transferred to veins travelling back towards the trunk. This maintains the trunk temperature while preventing heat loss from the skin.

QuestionChoice
This is incorrect. Countercurrent exchange helps with heat conservation, not oxygen transfer. Heat from warm blood in arteries travelling towards to skin is transferred to veins travelling back towards the trunk. This maintains the trunk temperature while preventing heat loss from the skin.
