Quiz Notecards

26
Q
  1. What is the endoplasmic reticulum?
A

They transport proteins.

25. Lab-Edible Cell

27
Q
  1. How does skin help maintain body temperature if a person becomes cold?
A

Blood vessels in the skin skin constrict to decrease the amount of blood that flows through them. This allows heat to move from the body into the outside environment. Swear glands in the skin stand up because the arrector pili muscle has contracted which produces goose bumps on the skin reducing skin surface area.
23. Notes- Homeostasis

28
Q
  1. How does skin help maintain body temperature if a person becomes warm?
A

The skin helps maintain body temperature if a person is warm by laying down the hair shafts, producing sweat, and making the blood vessels bigger.
23. Notes- Homeostasis

29
Q
  1. What is the Golgi body?
A

Receives proteins from endoplasmic reticulum
