Correct Answer(s)
A. 10 000 nerve endings
C. 12 million cells
D. 200 sudoriferous glands

Explanation
The skin is made up of various components, including nerve endings, cells, and sudoriferous glands. Nerve endings are responsible for transmitting signals to the brain, allowing us to feel sensations such as touch, temperature, and pain. The skin contains approximately 10,000 nerve endings, enabling us to have a sense of touch and perceive our surroundings. Additionally, the skin is composed of millions of cells, which play a crucial role in protecting the body from external factors and maintaining its overall health. Lastly, sudoriferous glands are responsible for producing sweat, which helps regulate body temperature. The skin contains around 200 sudoriferous glands, allowing us to perspire and cool down when necessary.

The skin acts to maintain homeostasis by the regulation of body temperature.

A.

True
B.

False

Correct Answer
A. True

Explanation
The skin plays a crucial role in maintaining homeostasis by regulating body temperature. When the body gets too hot, the skin helps cool it down through the process of sweating. Sweat is produced by sweat glands in the skin, and as it evaporates, it cools the body. On the other hand, when the body gets too cold, the skin helps to conserve heat by constricting blood vessels and reducing blood flow to the skin's surface. This helps to keep the body warm. Therefore, the statement "The skin acts to maintain homeostasis by the regulation of body temperature" is true.
