Final answer:
The adrenal glands are endocrine glands located above the kidneys. They produce hormones such as adrenaline and cortisol which are important for the body's stress response and metabolism. The adrenal glands consist of the adrenal cortex and the adrenal medulla, each producing different types of hormones.
Step-by-step explanation:
The adrenal glands are endocrine glands that produce a variety of hormones. The two adrenal glands are located on both sides of the body, just above the kidneys. Each gland has two layers: an outer layer called the adrenal cortex and an inner layer called the adrenal medulla.
The adrenal cortex produces steroid hormones called corticosteroids, such as cortisol and aldosterone. Cortisol helps control metabolism and suppresses the immune system, while aldosterone helps regulate mineral balance in the body. The adrenal medulla produces non-steroid hormones called catecholamines, including adrenaline and noradrenaline, which are involved in the fight-or-flight response.
So, the correct answer is option 1) Glands that produce adrenaline.
