Discriminate between endocrine, exocrine, paracrine, and autocrine.
- Correct Answer - Endocrine glands secrete hormones directly into the
bloodstream and have no ducts. Exocrine glands secrete hormones into
the epithelium and parade of the body through ducts. Paracrine secrete
into interstitial fluid to effect bear by cells. Autocrine glands secretion
effects the cell it secretes from.
Choose one of the endocrine glands and tell what hormone the gland
secretes. Explain the function of each hormone and how the gland is
regulated.
- Correct Answer - I choose the parathyroid gland. The parathyroid gland
secretes parathyroid hormone (PTH). Parathyroid hormone stimulates
the release of calcium by bones into the bloodstream, absorption of
calcium from food by the intestines, and the conservation of calcium by
the kidneys. The parathyroid gland is regulated by the negative feedback
of calcium levels in the blood to the parathyroid glands.
