    Study Notes

    Hormones and Endocrine System

    • Protein-based hormones exert their effects through second messengers
    • Hormones are chemical substances secreted by cells that regulate metabolic function in other cells
    • The pituitary gland is the master gland of the endocrine system
    • Hormone secretion in response to changing blood ion levels is known as humoral stimulus
    • PTH (parathyroid hormone) controls reabsorption of phosphate in the kidneys
    • Aldosterone is involved in regulating sodium and water reabsorption in the kidneys
    • ADH (antidiuretic hormone) is released by the pituitary gland in response to thirst center signals

    Thirst Center and Osmoregulation

    • The thirst center is located in the hypothalamus
    • The thirst center signals the pituitary gland to release ADH

    Buffer Systems

    • The most plentiful and powerful intracellular buffer system is protein
    • The respiratory system eliminates carbonic acid by eliminating carbon dioxide
    • The lungs and kidneys are the most important physiological buffer systems

    Vitamins and Nutrition

    • Vitamins are coenzymes needed to help the body utilize essential nutrients
    • Lipids are important for forming cell membranes and providing energy
    • Fiber is not one of the major nutrients the body needs to survive

    Immunity and Inflammation

    • Passive immunity occurs when antibodies are passed from a pregnant mother to her fetus
    • Inflammation is characterized by localized increased capillary filtration, hyperemia, and swelling

    Reproductive System

    • Estrogen and progesterone maintain the integrity of the uterine lining and prepare the mammary glands to secrete milk
    • The corpus luteum is responsible for maintaining the uterine lining during the first two months of pregnancy
    • The correct sequence of preembryonic structures is zygote, morula, blastocyst
