Question 1

What precentage of inhalation goes to the alveoli?

Answer 1

30% on normal and 40 percent on large breath

Question 2

What is normal stroke volume?

Answer 2

0.075 L or 75 ml

Question 3

What is normal HR?

Answer 3

65-85 beats per minute

Question 4

What is normal CO?

Answer 4

4-8 L/min

Question 5

When we breathe more and take in more oxygen we can supply to the mitochondria of our cells which produces more of what?

Answer 5

ATP

Question 6

Ventilation-Perfusion ratio definition

Answer 6

Each alveolus must be ventilated with oxygen-rich gas and the surrounding capillary bed be perfused with oxygen-poor blood at the same time.

Question 7

What is ventilation perfusion?

Answer 7

It describes the pairing of pulmonary blood supply to alveolar gas volume

Question 8

What would the ratio be for blood to pass through lung to alveolar air ventilation?

Answer 8

1L of blood to pass through the lung for every 0.8 liters of alveolar air ventilation

Question 9

How do you find MRV?

Answer 9

Breath rate multiplied by TV. should be around 6 or 5
