- How many layers of skin cells are found in the epidermis?
Billions
1 million
5
None of these
5
- Notes- Skin Brainpop
- How does the skin help regulate body temperature?
By enabling excess heat from the body
By blocking info about the environment
By allowing body temperatures set point to change when the weather is cooler or warmer
By removing wastes from the body
By enabling excess heat to escape from the body
- Notes- homeostasis
- Sweat glands:
Are not involved in the homeostasis of body temperature
Aid in cooling the body
Produce a secretion that oils hair and skin
Serve as anchors for the arrector pili muscle
Aid in cooling the body

- Mary has finished a large meal. Her blood is being flooded with sugar from this meal. How does her body prevent her blood sugar from going to high?
Glucagon will cause glucose that is stored in the liver to enter her blood
Her pancreas will secrete glucagon. Glucagon will cause the sugar to move into the body cells from the blood.
Insulin will cause glucose that is stored in the liver to enter her blood
Her pancreas will secrete insulin. Insulin will cause sugar to convert into glycogen to be stored in the liver.
Her pancreas will secrete insulin. Insulin will cause the sugar to convert into glycogen to be stored in the liver.

Adrenaline

- Describe how skin helps maintain body temperature if a person becomes warm/cold
Blood vessels in the skin constrict to decrease the amount of blood that flows through them. This allows heat to stay inside the body. Sweat glands in the skin reduce perspiration to none. Hairs on the skin stand up because the arrector pili muscle has contracted which produces goose bumps on the skin reducing skin surface area.
Blood vessels in the skin enlarge to increase the amount of blood that flows through them. This allows heat to movefrom the body into the outside environment. Sweat glands in the skin produce perspiration.
- Which of the following help cool the body?
Evaporation of sweat from the skins surface
Decreased blood flow to the skin
Abslrbsion of excess sweat
Abslrbsion of ultra violet rays
Evaporation of sweat from the skin surface
- Notes- homeostasis
