In this lesson, we'll discuss the functions of the anterior and posterior portions of the pituitary gland, the hormones they release and the relationship with the hypothalamus.

The Thyroid Gland: Functions, Calcitonin & TSH

3. The Thyroid Gland: Functions, Calcitonin & TSH

Your thyroid gland produces the hormones T3 and thyroxine (T4), which play a role in metabolism. Your thyroid also produces calcitonin, which helps regulate blood calcium levels. In this lesson, you will learn about the thyroid gland and its hormones, including how they are regulated by TSH.

Pancreas: Functions, Anatomy & Insulin Production

4. Pancreas: Functions, Anatomy & Insulin Production

The islets of Langerhans within your pancreas produce the hormones insulin and glucagon. In this lesson, you will learn how these hormones regulate your blood sugar level in opposite ways.

Adrenal Glands: Function, Cortex & Medulla

5. Adrenal Glands: Function, Cortex & Medulla

The adrenal glands sit on top of your kidneys and are comprised of an inner medulla region that is enclosed by the outer adrenal cortex. Both portions of the adrenal gland secrete hormones that regulate body functions and help maintain internal balance.

Hormones of the Testes and Ovaries: Functions & Anatomical Features

6. Hormones of the Testes and Ovaries: Functions & Anatomical Features

The testes and the ovaries secrete steroid hormones that help you grow and develop. In this lesson, we will learn about the female hormones, estrogen and progesterone, and the male hormone, testosterone, and how these hormones influence the development of secondary sex characteristics.
