TESTE DEIN WISSEN

What enables good thermoregulation of the skin in warm weather and cooler conditions?

What mediates this?

Lösung anzeigen
TESTE DEIN WISSEN

Good perfusion (flow) in warm weather allows greater heat loss, while blood supply to the skin is reduced via vasoconstriction to preserve body heat in cooler conditions. 


This is mediated by arteriovenous anastomoses (connections between small arteries and veins).
