distinguish between exocrine & endocrine glands

What are the organs that are not exclusively endocrine glands, but contain cells that secrete hormones? (13)

- the hypothalamus. -thymus. -pancreas. -ovaries. -testes. -kidneys. -stomach. -liver. -small intestine. -skin. -heart. -adipose tissue. -placenta.

Endocrine gland

-A gland that secretes hormones into interstitial fluid and then the blood; a ductless gland.

What is the basic difference between endocrine glands and exocrine glands?

Secretions of endocrine glands diffuse into interstitial fluid and then into the blood; exocrine secretions flow into ducts that lead into body cavities or to the body surface.

are endocrine glands vascular?

-Yes, because of their dependence on the cardiovascular system to distribute their products, endocrine glands are some of the most vascular tissues of the body.

Exocrine glands

-secrete their products into ducts that carry the secretions into body cavities, into the lumen of an organ, or to the outer surface of the body. -include sudoriferous (sweat), sebaceous (oil), mucous, and digestive glands

What are the endocrine glands of the human body? (5)

-the pituitary. -thyroid. -parathyroid. -adrenal. -pineal glands.

What are the functions of hormones?

1. Help regulate: • Chemical composition and volume of internal environment (interstitial fluid). • Metabolism and energy balance. • Contraction of smooth and cardiac muscle fibers. • Glandular secretions. • Some immune system activities. 2. Control growth and development. 3. Regulate operation of reproductive systems. 4. Help establish circadian rhythms.
