adrenal gland

each of the two KIDNEYS within the body bears an adrenal GLAND on its upper surface. The adrenal glands are important ENDOCRINE organs, producing HORMONES that regulate various body functions. Each adrenal gland has two parts, an outer cortex and an inner medulla, which secrete a variety of hormones. Two of the most important ones are ADRENALINE and CORTISONE .
