In total, the average mans lungs can contain 5800ml of air and an average womans lungs can contain 4050ml of air, however, it is only possible for a man to forcefullly exhale 4600ml of this air, and a woman can only forcefuly exhale 3150ml. If the remaining air were to be removed from the lungs they would collapse.

In normal rested breathing, an average male breaths in and out 500ml of air, and an average women breaths in and out 350ml of air. This volume is called the tidal volume.
If an average man were to forcefully inspire as much as possible, he could breath in an additional 3000ml of air. An average women could forcefully breath in an additional 2000ml. This additional volume that can be inspired is called the inspirational reserve volume.
If an average man were to forcefully expire as much air as possible, he could push out about 1100ml of air in addition to the normal 500ml. An average women could forcefully push out an additional 800ml. This additional volume that can be exspired is called the exspirational reserve volume.
There is an additional 1200ml of air in an avergae mans lungs, and an additional 900ml of air in an avergae womens lungs that they cannot blow out. This volume is called the residual volume.
What else can I help you with?
What type of air is residual volume?
Residual volume is the air that remains in the lungs after a maximal exhalation. It is considered a type of "stale" or stagnant air that cannot be voluntarily expelled and helps keep the lungs inflated.
What is residual volume of air?
Residual volume of air is the volume of air remaining in the lungs after maximal exhalation. It is not possible to voluntarily exhale this air, as it helps to keep the lungs inflated and prevents them from collapsing. Residual volume plays a key role in maintaining the oxygen-carbon dioxide exchange in the lungs.
What is the air left in your lungs after you exhale called?
The air left in your lungs after exhaling is called "Expiratory Reserve".
What muscle allows the lungs to fill the lungs with air?
The diaphragm. (located beneath the lungs) When it contracts it moves down, thus expanding the volume of the lungs. This causes the pressure in the lungs to decrease and air to flow in to the lungs. (pressure is inversely proportional volume- Boyle's law) This is inhaling. When the diaphragm relaxes it moves back up, decreasing the volume of the lungs and increasing the pressure which forces the air out. This is exhalation.
What is the difference between functional residual capacity and residual volume in the context of pulmonary physiology?
Functional residual capacity (FRC) is the volume of air remaining in the lungs after a normal exhalation, while residual volume (RV) is the volume of air remaining in the lungs after a maximal exhalation. FRC includes both the expiratory reserve volume and the residual volume, while RV is the volume of air that cannot be exhaled from the lungs.
The amount of air that can no be exhaled is called?
The residual volume is the volume of air remaining in the lungs after the most powerful expiration.
The lungs contain a certain amount of air that cannot be forced out the volume of air is known as what?
this is called residual volume.
Under what conditions does air tend to flow into the lungs?
Air tends to flow into the lungs when thoracic volume increases and pressure decreases. When the opposite is true, air leaves the lungs.
What happens to the volume of air in your lungs when you ascend to the surface of the ocean?
The air in your lungs expands in volume as you get closer to the surface of any water you swim in. This is because the air was compressed when deeper due to the pressure of the water around you. This is why when scuba divers always exhale while ascending to avoid rupturing their lungs as the air expands.
Explain what the term TIDAL volume means?
The volume of air moved into or out of the lungs during quiet breathing.
Air exhaled after normal exhalation is?
known as residual volume, which is the air that remains in the lungs even after a complete exhalation. It helps to keep the lungs open and prevents lung collapse. Residual volume cannot be expelled from the lungs voluntarily.
What is the difference between tidal volume and residual volume and pulmonary?
Tidal volume is the volume of air that moves in and goes out in asingle stroke, and is abut 500ml.
