Ronda: The adrenal gland is the most important, let me begin by explaining to you, what this gland is all about. Adrenal Gland What are adrenal glands? No bigger than a walnut and weighing less than a grape, each of your two adrenal function glands sits like a tiny pyramid on top of a kidney ("ad" "renal" means "over" the "kidneys"). But don't let their small size fool you; these powerful little hormone producing glands manufacture and secrete almost 50 different hormones, including steroid hormones such as adrenalin, cortisol, aldosterone, estrogen and testosterone that are absolutely essential to your health and vitality. They not only significantly affect the functioning of every single tissue, organ and gland in your body; they also have important effects on the fluid balance control and blood sugar regulation. They even regulate how you think and feel and determine how effective your immune system functions (Wilson, L., J. M.D.,2001).

What do the adrenal glands do? The adrenal glands have two layers: the cortex and the medulla. The adrenal gland is like a peanut butter sandwich where the peanut butter is the medulla and the cortex is the bread. Each layer in this sandwich makes different hormones. The medulla is located in the center of the gland and makes adrenaline. Adrenaline - the hormone that helps control the "fight or flight" response and puts the body on "high alert" (also known as epinephrine) and noradrenaline. These hormones are also known as epinephrine and norepinephrine. These hormones control the "fight or flight response" i.e. put your body on "high alert." These hormones increase the heart rate, increase blood pressure, increase the amount of oxygen you breathe in, and temporarily improve the eyesight. Adrenaline also causes the liver to release extra glucose, Glucose - sugar used by the body as energy

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
