3. You tell the patient to breathe normally when they have exhaled normally you instruct them to Exhale as much air as possible you measured this volume. This volume is known as the select any appropriate answers
inspiratory capacity
residual volume
expiratory Reserve volume
vital capacity
tidal volume
4. which of the following statements are accurate select any appropriate answers
during inspiration to diagram will contract to move in inferiorly this will decrease the thoracic volume and allow gas to enter the lungs
during inspiration ribs and sternum will elevate this causes the volume to increase and allows air to be pulled into the lungs.
During inspiration to diagram with contract to move Superiorly. this will decrease the thoracic volume and allow gas to enter the lungs
during inspiration muscles contract to decrease intrapulmonary pressure
during inspiration and ribs and sternum will depress this causes the thoracic volume to decrease and allows air to be pulled into lungs
5.Boyles law can be written as P1V1 equals p2v2 what must happen for air to enter the lungs select any appropriate answers
the pressure of gas in the lungs must be higher than atmospheric pressure
the pressure of gas in the lungs must be lower than the atmospheric pressure
the volume of gas in the lungs must be higher than ever the atmospheric volume
answer not listed
the volume of gas in the lungs must be equal to atmospheric volume
6.Which of the following muscles contract to promote exhalation are forced expiration breathing out
select any appropriate answers

the soft tissue that hangs at the end of the soft palate
the opening or slit in the trachea through which air will pass before it can enter the lungs
Explanation / Answer
The answers are
1. alveoli.
Alevoli is the ends of the respiratory tree, it ends either sacs or ducts. These are the responsible for the direct gas transfer.
2. The answer is Larynx
The pathway is Nose > Pharynx > Larynx > Trachea > Bronchi >Bonchioles > Alveoli
