What is the hormone that signals the kidneys to regulate the amount of water in the body?
antidieuritc
- Notes - Homeostasis notability
- When the body temperature becomes abnormally high, thermoregulatory homeostasis is maintain by what?
an increase in sweat gland activity and an increase in blood flow to the skin
- Notes - Homeostasis notability
What do sweat glands do?
aid in cooling the body
- CLF - SKIN Diagram notability
- What is the protein that helps protect the skin and underlying tissue?
keratin
- Notes - Homeostasis notability
- Mary has finished eating 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?
Her pancreas will secrete insulin. Insulin will cause the sugar to convert tissue glycogen to be stored in the liver
- Notes - Homeostasis notability
- Which of the following will help cool the body?
decreased blood flow to the skin
absorption of excess sweat
evaporation of sweat from the skin’s surface
absorptions of ultraviolet light rays by the skin
evaporation of sweat from the skin’s surface
- Notes - Homeostasis notability

positive feedback
- Notes - Homeostasis notability
- How many layers of skin cells are found in the epidermis?
5

85. Which of these illustrates an example of positive feedback? blood vessels dilating and you sweat urine production a woman nursing a baby a dog panting in the hot sun
a woman nursing a baby
- Notes - Homeostasis notability
- What do light skinned races such as Caucasians have?
approximately the same number of melanocytes as races with darker skins.

- Your dead skin cells make up what percentage of the dust in your house?
80%
- BP - Skin notability
- Fat is one type of what tissue?
connective tissue
- Notes - Histology notability
- What is the layer of skin that contains nerves and blood vessels?
dermis
- CLF - SKIN Diagram notability
- Describe how skin helps maintain body temperature if a person becomes too warm AND too cold.
If a person is too warm-
sweat is produced. sweat glands produce the sweat. Also the hairs on your skin lie flat. When a person is too hot, their blood vessels widen
When a person is too 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.
