Explanation:

TYPES OF GLANDS;

Gland :-

• It is an organ or tissue that secretes specific chemical substance for performing a particular function.

There are three types of glands

1. Endocrine glands
2. Exocrine glands
3. Heterocrine glands (Mixed glands)

Classification;

• On the basis of presence or absence of ducts, glands are classified into endocrine glands and exocrine glands.

Exocrine gland;

• It is a gland that pours its secretion on the surface or into a particular region.
• By means of ducts for performing a metabolic activity.
• Example, sebaceous glands, sweat glands, salivary glands, intestinal glands.

Endocrine gland;

• It is an isolated gland (separates even from epithelium forming it).
• Which secretes hormones that are poured into venous blood or lymph for reaching the target organ.
• Because the gland is not connected with the target organ by any duct.
• Example, hypothalamus, pituitary, thyroid, parathyroids, etc.

Heterocrine gland (Mixed gland);

• It is a gland that has both exocrine and endocrine regions.
• The former pouring their secretion through ducts,
• While the latter pouring their secretion directly into blood/lymph,
• Examples, pancreas, testes, ovaries, etc.
