Endocrine System and Feedback Review

If the environment gets cold, we will often shiver in order to:

• keep body temperature the same as the external temperature
• decrease body temperature
• increase body temperature
• regulate blood pressure

The body system that controls the functioning of the glands

• endocrine

• nervous

• blood stream

• digestive

Negative feedback is when changes occurring,

• return the body to the original condition

• return the body to a different condition

The diagram provides information about some of the digestive enzymes produced by the human pancreas. Another important molecule not shown in the diagram is also produced by the pancreas. It functions to decrease glucose levels in the blood. This molecule is

• progesterone

• insulin

• testosterone

• ATP

The end products resulting from the action of amylase would most likely be

• starches and proteins

• carbon dioxide and water

• amino acids

• simple sugars

Insulin is a molecule, produced by the endocrine system, which regulates sugar concentration in the blood. Most likely, insulin is a
