Document Summary

2 types of glands: endocrine and exocrine glands. Endocrine glands are made of secretory cells that release their products called hormones. Hormones move from the cells that produces them and diffuse into the bloodstream. Endocrine system consists of endocrine glands and of organs that contain some endocrine tissues and have functions other than hormone secretion. Major endocrine glands are pituitary, thyroid, parathyroid, adrenal and pineal glands. Organs with endocrine tissues include hypothalamus, thymus, pancreas, ovaries, testes, heart and placenta as well as stomach, small intestines, kidneys. They affect only the target cell which has receptors to bind to the specific hormones. Lipid soluble hormones include steroid hormones: move easily through any cell"s plasma membrane, inside the target cell, they combine with receptor molecules in the cytoplasm, moves into the dna which activates certain genes. Stimulates that activate endocrine glands include signals from the nervous system, changes in the levels of certain ions or nutrients in the blood.
