Question

how does the endocrine system regulate body functions? it releases enzymes into the blood. it releases hormones into the blood. it releases glands into specific organs. it releases chemicals into specific organs

Explanation:

The endocrine system consists of glands that secrete hormones directly into the bloodstream. These hormones then travel to target cells or organs to regulate various body functions such as growth, metabolism, and reproduction. Enzymes are mainly involved in digestion and chemical reactions in cells (not the main way the endocrine system regulates body functions). Glands are part of the endocrine system structure, not something released. Releasing chemicals into specific organs is too vague compared to the specific role of hormones in the endocrine system's regulation.

Answer:

It releases hormones into the blood.
