In this case, the damper is normally opened by the force of the spring but can be closed by the force of the motor. Removal of electrical power re-opens the damper. This style of damper is advantageous because it is fail safe; if the control to the damper fails, the damper opens and allows air to flow.
The adrenal glands, located on the top of each kidney, are responsible for releasing different classes of hormones. The outer part of the gland, called the adrenal cortex, produces the hormones cortisol (pronounced KAWR-tuh-sohl) and aldosterone (pronounced al-DOS-tuh-rohn). The inner part of the gland, called the adrenal medulla (pronounced muh-DUHL-uh), produces the hormones adrenaline and noradrenaline.
Adrenal glands, triangle-shaped glands located at the top your kidneys, are crucial for the production of hormones your body needs to survive. The outer part of the gland, known as the adrenal cortex, produces hormones involved in regulating a variety of body functions. The inner part, the adrenal medulla, produces hormones that play an important role in stress response. Sufficient intake of certain vitamins can help support adrenal gland health.
