What would happen if surfactant were not present quizlet?

What would happen if surfactant were not present quizlet?

What would happen if surfactant were not present? Small alveoli will collapse, large alveoli will expand.

Why is surfactant important quizlet?

Surfactant reduces surface tension throughout the lung. It is also important because it stabilizes the alveoli. That is, at a constant surface tension, small alveoli will generate bigger pressures within them than will large alveoli.

What would happen to the alveoli of surfactant was not produced?

Without normal surfactant, the tissue surrounding the air sacs in the lungs (the alveoli) sticks together (because of a force called surface tension) after exhalation, causing the alveoli to collapse.

What would happen to the alveoli of surfactant were not produced quizlet?

What would happen to the alveoli if surfactant were not produced? Without surfactant, the alveoli would collapse as a result of surface tension in the thin layer of water that moistens the alveolar surfaces. Trace the path air takes in flowing from the glottis to the respiratory membrane.

What would likely be the effect of reduce surfactant in the respiratory system?

Surfactant reduces surface tension. Without surfactant, the wet surfaces of the alveoli in your lungs would stick together and your lungs would not be able to expand – so, you would not be able to breath.

What is the role of surfactant in respiration?

The main function of surfactant is to lower the surface tension at the air/liquid interface within the alveoli of the lung. This is needed to lower the work of breathing and to prevent alveolar collapse at end-expiration.

What is the purpose of the surfactant?

Function. The main functions of surfactant are as follows: (1) lowering surface tension at the air–liquid interface and thus preventing alveolar collapse at end-expiration, (2) interacting with and subsequent killing of pathogens or preventing their dissemination, and (3) modulating immune responses.

What is the importance of surfactant in the respiratory system?

Pulmonary surfactant is essential for life as it lines the alveoli to lower surface tension, thereby preventing atelectasis during breathing. Surfactant is enriched with a relatively unique phospholipid, termed dipalmitoylphosphatidylcholine, and four surfactant-associated proteins, SP-A, SP-B, SP-C, and SP-D.

What are the three physical factors that influence ventilation?

Three physical factors influence the ease of air passage and the amount of energy required for ventilation.

• Airway resistance.
• Alveolar surface tension.
• Lung compliance.

What would blockage of the trachea do to blood pH?

How would blockage of the trachea affect blood pH? Blockage of hte trachea would interfere with the body’s ability to take in oxygen and eliminate carbon dioxide.
