Those who are not whizzes when it comes to the biology of the human body, have probably heard the term adrenal glands, but really have no idea as to what their function is within the body. However, most people do know that they are important.

Adrenal glands are found on top part of the kidneys and are in the shape or triangles. The adrenal gland is comprised of two parts, the adrenal cortex, which is the outside layer of the adrenal gland, and the adrenal medulla, which is the inner region of the adrenal gland. Each part has a specific job within the body that helps the person to be healthy and operate as they should.

The adrenal cortex secretes those hormones that have an effect on metabolism, chemicals in the blood and on certain body characteristics. For example, hormones that the body’s use of fats, proteins and so on. As well as hormones that affect the immune system.

The adrenal medulla is the part that helps the person cope with certain events, which means that it is not as major as the adrenal cortex. However, when you put them together they work as one which explains how people are the way that they are. The adrenal medulla is what is responsible for those stressors that are physical and emotional. For example, when the heart begins to speed up due to fear or excitement, the adrenal medulla is responsible for this action. In addition, this part of the adrenal glands can increase or decrease blood pressure as needed.

Working together, the adrenal glands are responsible for those women who go through a full term pregnancy since it is responsible for releasing hormones to control the pregnancy. In addition, puberty begins with the adrenal glands, as it is what starts the secretion of these hormones during these times. Overall, without the adrenal glands, people would be in a world of hurt, thus the significance of their value.
