Frage 3
Frage
In hot conditions the blood vessels [blank_start]dilate[blank_end] (or vasodilation occurs), so the vessels carry more [blank_start]blood[blank_end] and therefore carry more [blank_start]heat[blank_end]. Sweat [blank_start]glands[blank_end] produce more sweat which [blank_start]evaporates[blank_end] which takes energy. Therefore more energy / heat is [blank_start]lost[blank_end].
