Physiology of the Cardiorespiratory System

Question 1

cardiovascular endurance

Answer 1

the capacity of the heart to deliver blood and oxygen to working muscles during exercise

Question 2

pulmonary ventilation

Answer 2

getting oxygen into the blood

Question 3

Cardiac output

Answer 3

delivery oxygen to active tissues

Question 4

this process helps provide adequate blood and nutrients to the body

Answer 4

pulmonary ventilation
Cardiac output
extracting oxygen from the blood to complete the metabolic production of ATP

Question 5

Tidal volume

Answer 5

rate and depth of breathing

Question 6

when exercise starts

Answer 6

tidal rate and breathing rate increases

Question 7

Cardia output

Answer 7

= HRxSV ( heart rate x stroke volume)

Question 8

Storke volume

Answer 8

= quatity of blood pumped per heart beat

Question 9

Cardiac output at rest and during excercise

Answer 9

at rest 5 ltrs / minute
during excercise 20 to 25 ltrs /. minute
Highly trained 30 to 40 ltrs / minute

Question 10

Increase in Cardiac output is caused by

Answer 10

increase in HR and SV
