Understanding Endocrine Glands

Endocrine glands are specialized organs that secrete hormones directly into the bloodstream. These hormones regulate various bodily functions and maintain homeostasis.

Glands to Consider

1. Salivary Gland: This is an exocrine gland that secretes saliva into the mouth through ducts. It is not classified as an endocrine gland.

2. Sweat Gland: Similar to salivary glands, sweat glands are also exocrine glands. They secrete sweat onto the surface of the skin through ducts, hence not considered endocrine glands.

3. Thyroid Gland: This is a key endocrine gland that produces hormones such as thyroxine, which regulate metabolism and energy levels. It is classified as an endocrine gland.

4. Pituitary Gland: Known as the "master gland," the pituitary gland controls various hormonal functions of other endocrine glands. It releases several hormones directly into the bloodstream, thus it is an endocrine gland.
