Expiration: flow of gases out of lungs Inspiration and expiration: Mechanical processes caused by contraction of respiratory muscles Cause volume changes in thoracic cavity Volume changes lead to gas movement according to Boyle’s law (pressure varies inversely with volume): Volume changes cause ...

The device for forced deepening of the breathing and increasing the tidal volume of the lungs comprises the breathing tube with the valve providing for the resistance to the expired air. The inspired and expired air goes through the breathing tube. The valve represents the fragment of the wall ...
The purpose of this study is to analyse sexual dimorphism in human lungs during forced respiration using 3D geometric morphometrics. Eighty computed tomographies (19 males and 21 females) were taken in maximal forced inspiration (FI) and expiration (FE), and 415 (semi)landmarks were digitized ...
lowering the pressure inside the lungs and drawing air in from outside. Exhaling involves relaxation of the diaphragm and intercostal muscles, reducing the volume of the chest cavity and this, combined with the lungs' natural elasticity, serves to increase the pressure inside the lungs and move ...

The results are consistent with the idea that mechanical mixing within the tidal air and between the tidal and reserve air takes place only in the anatomical dead space of the lungs. Experiments with constant reserve volume on the ... J Heyder,CN Davies - 《Journal of Aerosol Science》 被引...
