Endocrine Gland
Endocrine glands are ductless glands that secrete hormones directly into the bloodstream. These hormones then travel to target organs or tissues where they regulate various physiological processes.
- Example: The pituitary gland is an endocrine gland located at the base of the brain. It secretes hormones that control growth, metabolism, and reproduction.

Exocrine Gland
Exocrine glands have ducts that carry their secretions to specific locations, such as the skin or digestive tract. These glands secrete substances like sweat, saliva, and digestive enzymes.
- Example: The salivary glands are exocrine glands located in the mouth. They produce saliva, which helps in the digestion of food.

Differences
- Endocrine glands secrete hormones directly into the bloodstream, while exocrine glands use ducts to release their secretions.
- Endocrine glands regulate physiological processes throughout the body, while exocrine glands usually have localized effects.
- Endocrine glands are involved in long-term and systemic regulation, whereas exocrine glands are more focused on immediate responses and local functions.
In conclusion, endocrine and exocrine glands play different roles in the body by secreting substances through different mechanisms and affecting various physiological processes. Understanding these differences is crucial in studying the functions of the endocrine and exocrine systems.
