Verified step by step guidance

Understand the definition of a purely endocrine organ: These are organs whose primary function is to produce and secrete hormones directly into the bloodstream.

Review the functions of the thyroid gland: It is a purely endocrine organ that produces hormones like thyroxine, which regulate metabolism.

Examine the pituitary gland: Known as the 'master gland,' it is purely endocrine and controls various other endocrine glands by releasing hormones.

Consider the adrenal gland: It is a purely endocrine organ that produces hormones such as adrenaline and cortisol, which help regulate metabolism, immune response, and stress.

Analyze the kidney: While it does have endocrine functions, such as producing erythropoietin and renin, its primary role is excretory, filtering blood to produce urine. Therefore, it is not a purely endocrine organ.
