Study Notes

Exocrine and Endocrine Glands

The nervous and endocrine systems work together to regulate organ activities and maintain homeostasis.
Endocrine glands secrete hormones directly into the bloodstream without the use of ducts.
Exocrine glands release enzymes through ducts to specific sites in the body.

Differences between Exocrine and Endocrine Glands

Ducts: Exocrine glands have ducts for secretion; endocrine glands are ductless.
Secretions: Exocrine glands produce enzymes, while endocrine glands produce hormones.
Location: Exocrine glands are localized near their action sites; endocrine glands can be distant from their target organs.
Examples: Exocrine glands include salivary and gastric glands; endocrine glands include the thyroid and adrenal glands.

Hormones

Hormones are produced by endocrine glands, also known as ductless glands.
They are released directly into the bloodstream and circulated throughout the body.
Hormones exert their effects on organs or tissues that are different from where they are produced.
Each hormone has specific target organs that regulate their function.
Imbalances in hormone levels, whether deficiency or excess, can lead to various disorders in the body.
