There are a number of factors that can cause confusion, from serious health problems to vitamin deficiencies. Alcohol intoxication is a common cause of confusion. Other causes include: A concussion is a brain injury that occurs as a result of head trauma.
The space under the lungs can be called as Lung Volume whereas force exerting by the atmosphere over an area is known as Air Pressure When Contraction occurs in lungs, Volume of lung decreases, and as we know, volume is inversely proportional to Pressure, pressure inside lung increases, and expiration occurs [ Removal of gas from lungs to atmosphere ] Now, when relaxation occurs, volume increases, pressure decreases, and inspiration occurs [ air travels from atmosphere to lungs ]
Alveolar pressure decreases to a sub-atmospheric level and. the pressure gradient for the flow of air into the lungs is established. Air flows into. the lungs and lung volume increases until the alveolar pressure rises to the. atmospheric level [0 cm H 2O] when the pressure gradient for flow of air into the.
