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
