Glands

Glands are organs in the human body that secrete substances such as hormones and enzymes. There are several types of glands, each with different functions and structures.

Types of Glands

1. Sweat Glands: These are found in the skin and are responsible for producing sweat, which helps regulate body temperature.
2. Salivary Glands: These glands produce saliva, which aids in digestion by breaking down food.
3. Endocrine Glands: These glands secrete hormones directly into the bloodstream. Examples include the pituitary gland, thyroid gland, and adrenal glands.
4. Exocrine Glands: These glands secrete substances through ducts. Examples include the pancreas, which produces digestive enzymes, and the sebaceous glands, which produce oil for the skin.
5. Sex Glands: Also known as gonads, these glands include the testes in males and the ovaries in females, and are responsible for producing sex hormones and gametes.

Functions of Glands

Glands play vital roles in maintaining homeostasis, regulating metabolism, and facilitating growth and development. They are also involved in the reproductive system and immune response.
