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.
