Air tends to flow out of the lungs when the internal pressure of the lungs is higher than the atmospheric pressure. This pressure difference is created by the contraction of the diaphragm and intercostal muscles during exhalation, which reduces the volume of the lungs and forces air out.
Under what internal conditions does air tend to flow into lungs?
in the lungs.
All of the rivers in Siberia tend to flow north. These rivers flow north as they being pulled to drain into the Arctic Ocean.
When a glacier moves by internal plastic flow, the basal layers, particularly those close to the glacier bed, tend to move faster than the upper layers. This is due to the increased pressure and heat at the base, which causes the ice to deform more readily. Additionally, the flow is often faster in the center of the glacier compared to the edges, as friction with the valley walls slows down the flow.
Anemics tend to have a lack of blood flow. They often tend to be cooler than most other people in their core body temperatures. They could also be paler in skin-tone or more easily tired doing everyday things.
In the atmosphere, to different areas of pressure
Not necessarily, but in general, yes.
Men generally have larger lung function because they tend to be more active then women, although it varies extremely between people.
Their skeletons tend to be on the outside
Yes it is true. When evaluating projects using internal rate of return projects having higher early year cash flows tend to be preferred at higher discount rates.
Gene flow tends to reduce diffences between populations.
