which of the following is considered a primary endocrine gland?
○ kidney
○ liver
○ pancreas
○ thyroid
○ heart

Explanation:

Primary endocrine glands are glands whose main function is hormone production. The thyroid gland is a primary endocrine gland that produces hormones like thyroxine which regulate metabolism. The kidney (produces erythropoietin but its main function is filtration), liver (produces some proteins but main function is detoxification etc.), pancreas (has both endocrine - exocrine functions), and heart (produces atrial natriuretic peptide but main function is circulation) are not primary endocrine glands.

Answer:

Thyroid
