If the value of the intrapleural pressure decreases, then the elastic recoil of the chest wall will proportionally decrease O lung volume will decrease O magnitude of the transpulmonary pressure will increase O value of the alveolar pressure becomes positive

In a normal healthy person breathing ambient air at sea level which one of the following will be true  less than 10mmHg difference between PAO2 (alveolar) and PzO2 (systemic)PaCO2(alveolar) has no effect on PaO2(systemic)more the 40mmHg difference between PACO2(alveolar) and PaCO2(systemic)PACO2(alveolar) is nearly 0mmHgAlveolar PACO2 is 100mmHg

What is the pressure of gas within the alveoli at the peak of inspiration, just before expiration, relative to atmospheric pressure? Less than atmospheric pressure Greater than atmospheric pressure O Equal to atmospheric pressure O Unable to be determined

The major function of the alveoli is to Select one: O a. moisten the air O b. filter dust and bacteria out of the air Ос. secrete mucus to trap foreign particles O d. provide a greater surface area for gas exchange May 9 Unproctored Jump to...

Normal, resting breaths are called: O Vital capacity O Functional residual capacity O Residual volume O Inspiratory reserve volume O Tidal volume

During expiration, the intra-alveolar pressure isa. lower than the pleural pressure.b. greater than the barometric pressure.c. lower than the barometric pressure.d. unchanged.

The rise of plasma hydrogen ions will cause O Hyperventilation O Has no effect on the respiratory system O Neither hyperventilation or hypoventilation O Both hyperventilation and hypoventilation Hypoventilation

Atmospheric pressure is less than Sam's alveolar pressure. Which of the following is TRUE? Sam's intrapleural pressure is decreasing. Sam's diaphragm is relaxed. Sam is inhaling.

Which of the the following will increase bronchiolar resistance? increased mucous  decreased alveolar elastin increased bronchial branching  increased smooth muscle tone

Why is it SO much harder to ventilate the lungs in a patient with pulmonary disease? Compared to ahealthy patient, what anatomical changes cause the difficulty in inspiration, and what anatomicalchanges cause the difficulty in expiration?
