question 24 of 25
how does the endocrine system affect the excretory system?
a. it provides the enzymes that allow for digestion.
b. it filters the blood that is used by the excretory system.
c. it adds oxygen to the bloodstream through diffusion.
d. it tells the excretory system when the blood is out of balance.

Explanation:

The endocrine system releases hormones. For example, the adrenal gland releases aldosterone which acts on the kidneys (part of the excretory system). Hormones from the endocrine system signal the excretory system (like the kidneys) to adjust processes (such as re - absorption of water and ions) when the blood composition (e.g., ion levels, water balance) is out of balance. Option A is incorrect as enzymes for digestion are mainly from the digestive system. Option B is about the function of the excretory system itself (like the kidneys filtering blood). Option C is a function related to the respiratory system (adding oxygen to the bloodstream).

Answer:

D. It tells the excretory system when the blood is out of balance.
