Anatomy The study of structure. Physiology The study of the functions of anatomical structures. All specific functions (physiology) are... performed by specific structures (anatomy). The chemical or molecular level of organizaton includes Atoms, proteins (arranged in molecules and filaments) What are the 6 levels of body organization? Chemical/molecular, cellular, tissue, organ, organ system, and organism. These organs are part of the Integumentary system skin, hair, sweat glands, and nails These organs are part of the Skeletal system bones, cartilage, associated ligaments, bone marrow These organs are part of the Muscular system skeletal muscles and associated tendons These organs are part of the nervous system brain, spinal cord, peripheral nerves, sense organs These organs are part of the Endocrine system pituitary gland, thyroid gland, pancreas, adrenal glands, gonads, endocrine tissues in other systems These organs are part of the Cardiovascular system hear, blood, blood vessels These organs are part of the Lymphatic system spleen, thymus, lymphatic vessels, lymph nodes, tonsils These organs are part of the respiratory system nasal cavities, sinuses, larynx, trachea, bronchi, lungs, alveoli These organs are part of the Digestive system Teeth, tongue, pharynx, esophagus, stomach, small and large intestine, liver, gallbladder, pancreas These organs are part of the Urinary system kidneys, ureters, urinary bladder, urethra These organs are part of the Male reproductive system testes, epididymides, ductus deferentia, seminal vesicles, prostate gland, penis, scrotum These organs are part of the Female reproductive system ovaries, uterine tubes, uterus, vagina, labia, clitoris, mammary glands 3 functions of the integumentary system protect against environment, regulate body temperature, provide sensory info 3 functions of the skeletal system support and protect other tissues, store calcium and other minerals, forms blood cells 3 functions of the muscular system provide movement, provide protection and support for other tissues, generate heat to maintain body temperature 3 functions of the nervous system direct immediate responses to stimuli, coordinate activities of other organ systems, provide and interpret sensory info 3 functions of the endocrine system direct long-term changes in activities of other organ systems, adjust metabolic activity and energy used by the body, controls structural and functional changes during development 2 functions of the cardiovascular system distribute blood, water, dissolved materials, distribute heat 2 functions of the lymphatic system defend against infection and disease, return tissue fluids to the bloodstream 4 functions of the respiratory system deliver air to the alveoli, transfer oxygen to the bloodstream, remove carbon dioxide from the bloodstream, produce sounds for communication 4 functions of the digestive system process and digest food, absorb and conserve water, absorb nutrients, store energy reserves 4 functions of the urinary system excrete waste from the blood, control water balance, store urine prior to elimination, regulate blood ion concentration and pH 2 functions of the male reproductive system produce sperm, suspending fluids, and hormones, sexual intercourse 4 functions of the female reproductive system produce oocytes, and hormones, support a developing embryo until delivery, provide milk to a newborn, sexual intercourse Homeostasis all systems working together to maintain a stable internal environment, or maintain a 'set point' Goldilocks principle a way of describing how everything must be 'just right' in homeostasis 2 mechanisms of Homeostatic regulation autoregulation and extrinsic regulation autoregulation Also known as intrinsic regulation. An automatic response in a cell, tissue, or organ to environmental change. Extrinsic Regulation: Responses controlled by nervous and endocrine systems and used to maintain homeostasis the two major control systems of the body the nervous and endocrine systems which system of control is faster, the nervous or the endocrine system? nervous stem the 3 parts of homeostasis regulation 1) receptor 2) control center 3) effector Receptor The part of homeostasis regulation that receives/senses the stimulus Control center The part of homeostasis regulation that processes the information, and sends a response message.
