Question

what do hormones do in the endocrine system? *
filter blood
act as messengers
produce waste
generate heat

Explanation:

In the endocrine system, hormones are chemical messengers. They are secreted by endocrine glands and travel through the bloodstream to target cells or organs, relaying signals to regulate various physiological processes. Filtering blood is done by the excretory system (e.g., kidneys), producing waste is not a function of hormones, and generating heat is related to metabolic processes in cells (not a primary function of hormones). So the correct option is the one stating hormones act as messengers.

Answer:

B. Act as messengers
