ANATOMY AND PHYSIOLOGY UNIT 1 TEST REVIEW homeostasis The body maintains stable internal conditions through feedback control mechanisms. Lymphatic/immune removes fluid from tissues, protects the body; destroys bacteria and tumor cells. endocrine controls the body with chemicals called hormones. skeletal provides muscle attachment cor movement; protects/supports body organs; sight of blood cell formation muscular moves limbs, allows facial expressions respiratory delivers oxygen...

MUSCLE PHYSIOLOGY TEST Skeletal Muscle Voluntary, striated muscle attached to bones multi nucleated Atrophy a decrease in muscle size due to disuse Hypertrophy excessive development of an organ or part Tendon end of muscles links muscle to bone Muscle contracts to produce movement Fascicle bundle of muscle fibers Muscle Fiber a single muscle cell Myofibril long structures inside muscle fibers made of sarcomeres Actin interacts with myosin for muscle contraction thin ...

PHYSIOLOGY TEST What happens to stroke volume during exercise as you increase you intensity from 20 to 40% of your VO2max? from 60 to 80%? As the intensity increases so does the SV because your body need more oxygen and nourishment - between 60-80 it will plateau What is the effect of body positioning on stroke volume and heart rate? Stroke volume during max exercise only slightly higher than supine stroke volume. What will the effect of a low blood pressure be on stroke volume? Why? ...

TEST REVIEW: PHYSIOLOGY OF CELLS IN ANATOMY AND PHYSIOLOGY Cell Membrane Boundary that encloses the cell and contains its contents; also called plasma membrane; regulates the movement of substances in and out of the cell; selectively permeable. Components of Cell Membrane Composed mainly of lipids and proteins, and some carbohydrates; consists of a double layer (bilayer) of phospholipids, with fatty acids turned inward and the water-soluble heads facing the surfaces. Structure of Cell Mem...
