Endocrine System and Hormonal Functions Quiz: Can You Ace It?

Questions: 15 | Attempts: 60 | Last updated: Oct 19, 2025

Sample Question
Choose the correct statement about ADH. (Antidiuretic Hormone)

It is a hormone that helps blood vessels constrict and helps the kidneys control the amount of water and salt in the body. A high ADH causes the body to produce less urine.

A hormone that helps blood vessels constrict and helps the kidneys control the amount of water and salt in the body. A high ADH causes the body to produce more urine.

Low ADH causes the body to produce less urine and ADH is released by the adrenal gland.

ADH doesn't controls the formation of urine in kidneys.
