When you are hot, blood vessels in the dermis in order to maintain homeostasis?

When a person is hot, the blood vessels in the dermis dilates, in order to maintain the homeostasis. When the temperature is increased, it becomes necessary to lose the body heat. This increased heat is lost by rushing the blood to the vessels present in the dermis layer. These blood vessels dilates so that more blood can flow inside these and the heat can be lost.

hence, the blank can be filled with 'dilate'.

stress fractures occur largely in the feet and legs and are common in sports that require repetitive impact, primarily running/jumping sports such as gymnastics or track and field.
