Here's why:
* Exocrine glands release their secretions through ducts that open onto an epithelial surface, such as the skin, the lining of the digestive tract, or the respiratory tract.
* Endocrine glands, on the other hand, secrete hormones directly into the bloodstream. These hormones then travel throughout the body to reach target cells and tissues.
Examples of exocrine glands include:
* Sweat glands: Secrete sweat to cool the body.
* Sebaceous glands: Secrete sebum (oil) to lubricate the skin and hair.
* Salivary glands: Secrete saliva to aid in digestion.
* Mammary glands: Secrete milk to nourish offspring.
* Lacrimal glands: Secrete tears to lubricate the eyes and wash away debris.
