The pituitary gland sits at the base of the brain. It is a small sized gland that is divided into three components: the anterior, intermediate, and posterior lobes. In humans, however, the intermediate lobe is essentially negligible, thus leaving the anterior and posterior and giving rise to the notion of the pituitary as two separate glands. Both lobes are responsible for secreting different sets of hormones that regulate various body functions like growth, blood pressure, and sexual gland functions. The anterior lobe produces eight hormones and the posterior lobe produces two hormones.
