Exocrine gland

Endocrine gland

Exocrine glands discharge their secretions through ducts.

These glands are ductless glands.

Their secretions reach body surface (internal or external).

Their secretions directly pour into the bloodstream and reach their target organ/cells.

Exocrine glands are mostly composed of enzymes and salts.

Endocrine glands are composed of hormones.

Examples: sebaceous glands, lacrimal gland, salivary gland, etc.

Examples: thyroid gland, pituitary gland, adrenal gland, pineal gland, etc.
