Final answer:
The adrenal glands are the endocrine glands associated with the kidneys, including regions that secrete different hormones and contribute to endocrine function.
Step-by-step explanation:
The endocrine glands that are associated with the kidneys are the adrenal glands. Each adrenal gland sits on top of a kidney; this includes both an outer adrenal cortex and an inner adrenal medulla, which secrete various hormones. While the adrenal glands are major endocrine structures associated with the kidneys, the kidneys themselves also have endocrine function, releasing hormones like renin in response to certain physiological triggers.
