33. Loose connective tissue (adipose, areolar) is found in the subcutaneous layer. It serves as

insulation and an energy source. Elastic connective tissue is found in the dermis and

between the subcutaneous tissue and the dermis. This elasticity permits skin to stretch

without injury. Circulating connective tissue (blood) is found in the dermis and

subcutaneous tissue. The blood transports nutrients and gases to and from skin cells and

helps maintain constant body temperature.

34. The eccrine sweat glands release a watery solution onto the skin, which evaporates and

thereby cools the body. The blood vessels in the dermis can dilate to increase heat loss to

the environment (under hot conditions) or constrict to minimize heat loss from the body

(under cold conditions).

Page 535. The main skin pigment is melanin from melanocytes. Blood pigments also provide skin

color. Hemoglobin gives skin a reddish color, but when hemoglobin is deficient or blood

flow is abnormally low, the skin has a bluish appearance. Circulating bile pigments from

the liver can give the skin a yellowish color. Some dietary pigments can also give color to

the skin. For instance, the carotene in some vegetables can give skin a yellow to orange

color.
