The skin has many important functions. One of them is thermoregulation. In response to feeling cold, the body will retain heat by _____ the vessels in theskin. In response to feeling hot, the body will loose heat by _____ the vessels in the skin.
- Dilating; constricting
- Constricting; dilating
Correct Answer

A. Constricting; dilating

Explanation

The skin plays a crucial role in thermoregulation, which involves maintaining the body's internal temperature. When feeling cold, the body will constrict the vessels in the skin to conserve heat. This narrowing of blood vessels helps to reduce blood flow near the skin's surface, minimizing heat loss. Conversely, when feeling hot, the body will dilate the vessels in the skin. By widening the blood vessels, more blood is brought to the skin's surface, allowing for increased heat dissipation through sweating and radiation.

In the Houston humidy, Ashley notices that she sweats a lot when she runs 3 miles in the late afternoon. There are different mechanisms that the body does to maintain the internal temperature from rising too high. Afterall, homeostasis keeps us alive. Which gland is responsible for the watery perspiration that helps cool the body?
- Apocrine (Sweat) Glands
- Merocrine (Eccrine) Sweat Glands
Correct Answer

A. Merocrine (Eccrine) Sweat Glands

Explanation

Merocrine (Eccrine) Sweat Glands are responsible for the watery perspiration that helps cool the body. These glands are distributed all over the body and produce sweat in response to an increase in body temperature. When we exercise or are in a hot environment, these glands secrete sweat onto the skin's surface, which then evaporates and cools the body. The sweat produced by these glands is mostly water and helps regulate body temperature by dissipating heat. Apocrine glands, on the other hand, are not involved in temperature regulation and produce a thicker, odorless sweat in response to emotional or stressful stimuli.
