Answer:
1. Acidic secretions from skin glands also stop the growth of fungi on the skin. ... The hypothalamus also causes dilation of the blood vessels of the skin, allowing more blood to flow into those areas, causing heat to be released from the skin surface.
2. Blood vessels supplying blood to the skin can swell or dilate - vasodilation. This causes more heat to be carried by the blood to the skin, where it can be lost to the air. Blood vessels can shrink down again - vasoconstriction. This reduces heat loss through the skin once the body's temperature has returned to normal.
3. "The takeaway"
If your internal temperature drops or rises outside of the normal range, your body will take steps to adjust it. This process is known as thermoregulation. It can help you avoid or recover from potentially dangerous conditions, such as hypothermia.
4. Skin. Sweat glands in the skin secrete a fluid waste called sweat or perspiration; however, its primary functions are temperature control and pheromone release. ... Sweating also maintains the level of salt in the body. In mammals, the skin excretes sweat through sweat glands throughout the body.
5. The integumentary system consists of the skin, hair, nails, glands, and nerves. Its main function is to act as a barrier to protect the body from the outside world. It also functions to retain body fluids, protect against disease, eliminate waste products, and regulate body temperature.
