Study Notes
Exocrine Glands
- Secrete products into ducts that transport secretions to body cavities, organ lumens, or the body's surface.
- Examples include sudoriferous (sweat), sebaceous (oil), mucous, and digestive glands.
Endocrine Glands
- Ductless glands that release hormones directly into interstitial fluid, which then enter the bloodstream.
- Vital for maintaining various physiological processes in the body.
Vascular Nature of Endocrine Glands
- Highly vascular due to a reliance on the cardiovascular system for hormone distribution.
- Among the most vascularized tissues in the body.
Major Endocrine Glands in Humans
- Key glands include:
- Pituitary
- Thyroid
- Parathyroid
- Adrenal
- Pineal
Additional Organs with Endocrine Functions
- Several organs contain hormone-secreting cells, including:
- Hypothalamus
- Thymus
- Pancreas
- Ovaries
- Testes
- Kidneys
- Stomach
- Liver
- Small intestine
- Skin
- Heart
- Adipose tissue
- Placenta
Basic Differences Between Gland Types
- Endocrine glands secrete hormones into interstitial fluid, which then diffuse into blood circulation.
- Exocrine glands utilize ducts to direct secretions into body cavities or onto surfaces.
Functions of Hormones
- Regulate:
- Chemical composition and volume of interstitial fluid
- Metabolism and energy balance
- Contraction of smooth and cardiac muscle fibers
- Glandular secretions
- Immune system activities
- Control growth and developmental processes.
- Manage the functioning of reproductive systems.
- Aid in establishing circadian rhythms.
