Exocrine System:
1. Secretes substances outside the body through ducts.
2. Includes glands such as sweat glands, salivary glands, and digestive glands.
3. Secretions are released into the external environment or onto a surface within the body.
4. Functions include digestion, cooling the body, and lubricating surfaces.
Endocrine System:
1. Secretes hormones directly into the bloodstream.
2. Includes glands such as the pituitary gland, thyroid gland, and adrenal glands.
3. Hormones travel through the bloodstream to target organs or tissues.
4. Functions include regulating metabolism, growth and development, and maintaining homeostasis.

Exocrine System
- Definition: Consists of glands that secrete substances into ducts or tubes that transport the secretions to specific target sites.
- Types of Glands:
- Salivary glands
- Sweat glands
- Mammary glands
- Pancreas
- Liver
- Key Features:
- Secretions are not released directly into the bloodstream.
- Effects are localized to specific tissues or organs.
- Examples:
- Salivary glands secrete saliva into the mouth.
- Sweat glands secrete sweat onto the skin.
Endocrine System
- Definition: Consists of glands that secrete hormones directly into the bloodstream, which transports the hormones to target cells throughout the body.
- Types of Glands:
- Pituitary gland
- Thyroid gland
- Adrenal glands
- Ovaries
- Testes
- Key Features:
- Secretions are released into the bloodstream.
- Effects can be widespread and systemic, affecting multiple organs and functions.
- Examples:
- Pituitary gland secretes hormones that regulate growth, metabolism, and reproduction.
- Thyroid gland secretes hormones that regulate metabolism.
Comparison Table:
| Feature | Exocrine System | Endocrine System |
|---|---|---|
| Type of secretion | Ductal | Non-ductal |
| Target site | Specific tissues or organs | Many organs and tissues throughout the body |
| Mode of secretion | Through tubes or ducts | Directly into the bloodstream |
| Effects | Localized | Systemic |
| Examples | Salivary glands, sweat glands | Pituitary gland, thyroid gland |
