  2. Endocrine system • Endocrine system - all the endocrine (hormones) glands of the body. • Endocrine glands - glands that produce hormones - also known as 'ductless' glands. • Hormones - chemical substances that act as messengers in the body - slow acting and long term effects - unlike nerves which are fast acting. • Pituitary gland - the endocrine gland that controls the activities of other endocrine glands; it is often called the "master gland". • Hypothalamus - a portion of the brain that constantly checks the internal environment of the body and has both neural and hormonal roles.

  3. Endocrine system • Target cells - the cells on which a hormone acts. • Thyroid gland - large gland in the front of the neck, it secretes hormones which regulate growth and metabolism • Thymus - a ductless glandular organ at the base of the neck that produces lymphocytes and aids in producing immunity

  4. Endocrine system • Pancreas - located partially behind the stomach in the abdomen, and it functions as both an endocrine and exocrine gland. It produces digestive enzymes as well as insulin and glucagon • Adrenal gland - one of a pair of ductless glands, located above the kidneys, which produce adrenaline (epinephrine) • Ovaries - The female sex glands that store the ova and produce female sex hormones • Testes - The male gonads, which produce sperm and secrete male sex hormones.

  5. Endocrine system • Homeostasis - the process of maintaining a constant internal environment eg 37 degrees body temp. • Endothermic - able to maintain a constant body temperature. • Metabolism - all the chemical reactions occurring in the cells.
