After oxygen is inhaled, air containing carbon dioxide (waste for humans, though nutrient for plants) is reflexively exhaled. It is in this manner that air tends to flow out of the lungs.
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.
Pulmonary atresia is a congenital heart defect where the pulmonary valve does not form properly, leading to a blockage of blood flow from the heart to the lungs. This condition can result in low oxygen levels in the blood and may require surgical intervention to improve blood flow to the lungs.

Rocks will flow under extreme heat and pressure, causing them to deform and behave like a viscous fluid over long periods of time. This process is known as rock deformation and occurs deep within the Earth's crust where temperatures and pressures are high.
There are no nerves located within the lungs themselves. However, the lungs are innervated by the pulmonary plexus, which consists of autonomic nerves that regulate functions such as breathing, blood flow, and airway constriction.
Inhalation. Breathing.

when pressure inside the lungs is lower then outer atmosphere
Under what internal conditions does air tend to flow into lungs?
Air tends to flow into the lungs when thoracic volume increases and pressure decreases. When the opposite is true, air leaves the lungs.

There is no gene flow.
There are no muscles in the lungs that help inhale or exhale, this is the job of the diaphragm.
it stunts blood flow from getting to the lungs
The flow of blood from the heart to the lungs and back to the heart is called pulmonary circulation.
