What is the opposite of constrict?

How do capillaries help control the amount of heat lost from the body?
They dilate at the surface of the skin to release heat into the atmosphere, and they can also constrict to reduce heat loss through the skin.
Does adrenaline constrict pupils of the eyes?

Histamine
Why are capillaries not open all the time?
Capillaries are not open all the time to regulate blood flow and maintain blood pressure. By being able to constrict or dilate, they can control the amount of blood flowing through the tissues according to the body's demand, whether it be during rest or when more oxygen and nutrients are needed during physical activity.
How do the capillaries adjust to changes in temperature?
Capillaries adjust to changes in temperature primarily through the process of vasodilation and vasoconstriction. In response to increased temperatures, capillaries dilate, allowing more blood to flow to the surface of the skin, facilitating heat loss through radiation and convection. Conversely, in colder temperatures, capillaries constrict to reduce blood flow to the skin, helping to conserve body heat. This dynamic adjustment helps maintain overall body temperature homeostasis.
What happens to both pupils when light enters?
