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 ]
Lung volumes and lung capacities refer to the volume of air associated with different phases of the respiratory cycle. Lung volumes are directly measured. Lung capacities are inferred from lung volumes.
