Update 100% Pass
Cardiorespiratory fitness - CORRECT ANSWER-The ability of the cardiovascular
and respiratory systems to supply oxygen and nutrients to large muscle groups to
sustain dynamic activity
Respiratory system - CORRECT ANSWER-The body system responsible for the
exchange of
gases between the body and atmosphere
Cardiovascular System - CORRECT ANSWER-The body system responsible for
the delivery of oxygen and nutrients to body tissues (via blood within vessels) and
the delivery of carbon dioxide and other wastes back to the heart and lungs
Air passageways - CORRECT ANSWER-Warm/humidify/filter air, promoting
optimal gas exchange (O2 in, CO2 out)
Lungs - CORRECT ANSWER-Facilitate movement of O2 → blood, and
facilitates respiration (exchange of O2 and CO2)
, Heart - CORRECT ANSWER-4 chambers that pump blood through two different
circulatory systems
Pulmonary circuit - CORRECT ANSWER-Blood: heart →Pulmonary artery →
lungs → Pulmonary vein → heart
Systemic circuit - CORRECT ANSWER-Blood: heart → Aorta → rest of body →
Vena Cava → heart
Blood vessels - CORRECT ANSWER-- Transport blood throughout the body via
arteries and veins
- O2/CO2 exchange in capillaries
2 phases of cardiac cycle - CORRECT ANSWER-Systole and Diastole
Systole - CORRECT ANSWER-- top number in blood pressure
- Ventricles contract/eject blood
- Peak force on vessel wall
- Semilunar valves open
Diastole - CORRECT ANSWER-- bottom number in blood pressure
- ventricles relax/blood fills chambers
- Semilunar valves close, AV valves open
Cardiac output variable - CORRECT ANSWER-(Q) = liters/min (blood flow)
