29.The hormone that signals the kidneys to regulate the amount of water in the body is
Antidiuretic
- Notes- homeostasis
- For a cell to move from the basal layer to top layer of the epidermis takes approximately
2 weeks
- WKST- the skin
- Which of the following animals is homeothermic?
Cat
Turtle
Snake
Shark
Cat
- Notes- homeostasis
- 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
- In the lab, what did we put the water with different temperatures in?
Beaker
- Lab- temperature and enzyme
- Skin is NOT made of which of the following tissues?
Nervous
Connective
Smooth
Epithelial
Smooth
- Notes- histology
- BP- skin
- Light-skinned races such as Caucasians have
Approximately the same number of melanocytes as races with darker skins
- BP- skin
- Your dead skin cells make up what percentage of dust in your house?
80%
- BP- skin
- The dependent variable in our experiment is illustrated by the
Height of column of bubbles
- Lab- temperature and enzyme
- Limiting sun exposure helps to prevent skin _______, a disease in which cells divide uncontrollably.
Cancer
iBooks: cell cycle
- The layer of skin that contains nerves and blood vessels is the
Dermis
- CLF- skin diagram
- What organelle in the cell distributes proteins?
Golgi Body
- Lab - edible cell
- Describe how skin helps maintain body temperature if a person becomes cold.
Blood vessels in the skin construct to decrease the amount of blood that flows through them. This allows heat to stay inside body. Sweat glands in the skin reduce perspiration to none. Hairs stand up because the arrestor pili muscle has contracted which produces goose bumps on the skin reducing skin surface area.
- Notes- homeostasis
- Describe how skin helps maintain body temperature if a person becomes warm.
Blood vessels in the skin enlarge to increase the amount of blood that flows through them. This allows heat to move from the body into the outside environment. Sweat glands in the skin produce perspiration. As the perspiration evaporates, it carries heat into the air. Hairs on the body lie flat. Skin smoothes out to allow heat out.
- Notes- homeostasis
- What are the two fibers of the dermis?
Collagen and Elastin
- BP- skin
