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.
High - each branch inside the lungs sub-divides many, many times. This dramatically increases the surface area in relation to the actual volume.
The volume of the chest increases due to the decrease in pressure in the lungs.
due to surface area. if you are taller your lungs will have a greater surface area which will raise the volume.
Lungs can rupture due to a buildup of pressure and the ost common cause of this is holding your breath when ascending. Due to Boyle's law, as the pressure decreases when you ascend, the volume increases. And if you do not exhale, the lungs will increase in volum to a point where one might rupture.
By providing a large area in the lungs.
What happens is that the air volume entering the alveoli also decreases. Tidal volume is the quantity of air that enters and leaves the lungs during quiet breathing.
The skin surface is not large enough for big creatures such as humans; therefore we have structures in our lungs that greatly increase the surface area.
Lungs can not and does not excrete salts from its surface.
If the surface area of the organism is small, then there is no problem with getting all the oxygen needed. If the surface area of the organism is large, therefore a special respiratory surface is needed. An example is lungs, gills. The ratio of surface area to volume in a small organism is greater than the ratio in a large organism.
The size of the cell is limited because of surface to volume ratio. It has limits such as environmental factors. Small animal have no trouble exchanges gases but the extremely large King Kong would not have enough surface area in the lungs to function at all.
what happens when you inhale is that air goes into your lungs and your lungs get bigger ...Actually, your diaphragm moves to expand the volume of your thoracic cavity, which pulls a partial vacuum on your lungs, causing them to expand FIRST...and THEN the partial vacuum created by your expanded lungs causes air to move into them. When you breath out, it causes the reverse to occur.
Air in your lungs is compressed by the pressure of the water. As the pressure of the water goes down (as you go up) then the air will expand. If you allow it to expand while trapped in your body, you can damage your ears and lungs. ascending means starting from least and moving towards highest
