PE anatomy

-
respiratory system
-
Alveoli is where gaseous exchange happens, o2 into blood stream and co2 diffuses out of blood and to the alveoli
At rest the diaphragm and intercostal muscles relax, rib cage moves in and down.
-
-
-
Aerobic -with oxygen, jogging, carbon dioxide and water produced
Anaerobic - without oxygen, high intensity act, sprint, latin acid produced,
Blood
Arteries - carries oxygenated blood at high pressure, thick walls. no valves
veins - carry blood at low pressures, carry deoxygenated blood, have valves
Capillaries - single cell think for gaseous change,

MUSCULAR SYSTEM
create movement, generate force by contracting which transfers to the bones and tendons
Muscle groups
Elbow - bicep, flexion, eg in the upward phase of bicep curl. tricep then extends when shoot ball in netball
Agonist - the working musle, shorter + contracts
Antagonist - co-ordinates the movement, lengthens and relaxes.
fixator, sygernist - stabilises the movement
Bicep curl upward phase - agonist bicep, antagonist tricep, fixator scapula.
-
SKELETAL SYSTEM
-
Synovial joint
freely movable, where 2 or more bones articulate
-
-
Joints
-
ball and socket joint - allows a wide range of movement- shoulder and hip - flexion, extension, adduction, abduction, rotation
hinge joint - allows movement in one plane, flexion, extension - elbow and knee
Short term effects
-
Cardio vascular - inc heart rate- more blood flow inc removal of waste. inc distribution of blood flow to the muscles
Respiratory - inc breathing rate, for gaseous exchange, inc oxygen availability
lONG TERM
Skeletal - inc bone density, muscle hypertrophy, inc muscular endurance
Cardio vascular - hypertrophy of heart, dec resting heart rate, in cardiac output
respiratory - inc aerobic capicity, inc tidal volume
Cardiovascular system
systemic circuit - transports oxygenated blood, from heart to body deoxygenated back to heart delievers oxygen and nutrients.
Pulmonary - Deoxygenated blood to the lungs and oxygenated blood back to the heart. removes carbon dioxide from blood
RISKS
Use personal protective equipment, correct clothing, appropriate level of comp, warm up and cool down
damage equipment, wet floor, hazard on playing surface, technique
