Terms in this set (32)
1. sensors, in the body to detect change and send info
2. integrating enter (CNS), which assesses change around a set point
3. Effectors, which can make the appropriate adjustments to counter the change from the set point
Ex. laying down to standing up. blood pressure falls, blood pressure receptors respond (sensors), brain(CNS) tells heart rate to inc.(effector), rise in blood pressure
contractingWhat is the function of muscle tissue-Skeletal -Cardiac -SmoothWhat are the types of muscle tissue (3)-Attached to bones at both ends by means of tendons; hence contraction produces movement -Striated muscle tissue -Hypertrophy -voluntary movementSkeletal muscle-Striated muscle tissue ( like a woven basket) -myogenic -involuntary contractionsCardiac muscle-Do not have striations -found in digestive tract, blood vessels, bronchioles, ducts or urinary and reproductive systems -involuntary movementSmooth muscle-conduct electrical signals to other cells -consists of neurons & neuroglia -Each neuron consist of cell body, dendrites, and axon -neuroglia serve to bind neurons together -Nervous tissue makes up the brain, spinal cord, and nervesWhat is the function of the Nervous tissue-linings and coverings of organs and cavities -specialized for: secretion and absorption(single layer simple epithelium) -protectionWhat is function of Epithelial tissue-connect, anchor, and support structures in the bodyWhat is the function of Connective tissue-connective tissue proper ( ECF matrix consists of protein/collagen fibers) -bone -cartilage -bloodWhat is a part of connective tissue-intracellular fluids(cytosol) -Extracellular fluids (plasma-blood vessels)(interstitial fluids -cell)What are the two compartments for body fluid-Integumentary: Protection, Thermoregulation -Nervous: Regulation of other body systems -Endocrine: Secretion of regulatory molecules (hormones) -Skeletal: Movement and Support -Muscular: Movements of the skeleton -Circulatory: Movement of blood and lymph -Immune: Defense of the body against invading pathogens -Respiratory: Gas exchange -Urinary: Regulation of blood volume and composition -Alimentary: Breakdown of food into molecules that enter the body -Reproductive: Continuation of human speciesList the 11 organ systems & their primary functionsProtection & ThermoregulationIntegumentary systemRegulation of other body systemsNervous sysemSecretion of regulatory molecules (hormones)Endocrine systemSupport and MovementSkeletal systemMovement of the skeletonMuscular systemMovement of blood and lymphCirculatory systemDefense of the body against invading pathogensImmune systemGas exchangeRespiratory sysemRegulation of blood volume and compositionUrinary systembreakdown of food into molecules that enters bodyAlimentary systemcontinuation of human speciesReproductive system
