The gland located at the top of the kidney is the ________ gland.
Elza [17]

Answer:

adrenal

Explanation:

The adrenal glands are two endocrine glands in the human body. They are located above the kidneys.  Members of the endocrine system, the adrenal glands are very important to the human body because they make hormones essential for their functioning.

These glands are also responsible for the production of hormones that act on the transformation of fat into glucose by the liver. An example of this hormone is glucocorticoid known as cortisol, which also acts on the degradation of triglycerides. These functions are also performed by the region of the adrenal cortex.

The adrenal glands also produce in the adrenal medulla two other important hormones: adrenaline (also known as epinephrine) and norepinephrine (also known as norepinephrine). These two hormones act on psychic and physical reactions generated by strong emotional situations (mainly related to emotional stress).
