LE Endocrine System Review 2022

What is the main function of the endocrine system?

• It creates chemicals, or hormones, that are sent around the body to maintain homeostasis.

• It creates electrical messages that are sent around the body to maintain homeostasis.

• It maintains the correct level of oxygen in the body to maintain homeostasis.

• It releases waste from the body to maintain homeostasis.

The process by which an organism’s internal environment is kept stable in spite of changes in the external environment.

• True

• False

Can a hormone affect any cell?

• Yes, they affect all cells

• No, the cell has to have a matching receptor

• Maybe

• Depends on the situation

How does a hormone identify its target cell?

• protein receptors on the cells surface

• it is only sent to its target cell

• neurons transmit the hormone signal

• glands are the target cell

How do hormones get to their target cells?

• nerve impulses

• floating in the blood stream or lymph fluid between the organs

• electric and chemical signals

• respiration
