Residual Volume
Residual volume is the amount of air left in the lungs after a maximal exhalation
residual volume
The residual volume is the volume of air remaining in the lungs after the most powerful expiration.
Tension pneumothorax which is where the lung cavity fills with air and crushes the remaining good lung.
Alveolar volume is lung capacity. Alveoli are the air sacs in the bronchioles. How much air the lungs hold during both inspiration and expiration is lung capacity which is alveolar volume. Hope this helps
Expiratory reserve volume is decreased in a patient with emphysema. This patient will struggle to breathe out because air is getting trapped within the lungs. There is also an increase of co2 in the blood because of the inability for the patient to exhale.
Inspiration, as called inhalation, moves air into the lungs. Expiration, as called exhalation, moves air out of the lungs.
Contraction of the rib cage causes an increase in internal lung pressure that results in the expiration of air from the lungs.
Inspiration happens when the pressure inside the lungs is lower than the atmospheric pressure (outside) and air rushes into the lungs. Expiration is when the air inside the lungs is higher than the atmospheric pressure and the air rushes out of the lungs. If the intrapleural pressure (pressure within the pleura of the lungs) isn't maintained then the pressure in the lungs can't differentiate between inspiration and expiration and so the lung collapses.
Vital Capacity
The air that can not be exhaled is called residual volume.TV = the amount of air displaced during normal breathing.IRV = The amount of air that can be taken in forcibly beyond tidal volumeErv= The amount of that can be expelled forcibly.Vital capacity = the total amount of exchangeable air.Total Lung capacity = TV + IRV + ERV + RESIDUAL VOLUME
Lung cells are little bubbles that take in air and take out air
