Upper respiratory tract

residual capacity and a liquid ventilator is used to generate tidal breathing with perfluorocarbon. During partial liquid ventilation, perfluorocarbon fluids are administered into the lungs to act as artificial surfactant for complications, like respiratory distress syndrome, or as a medium for other types of pulmonary dysfunction…

The respiratory system is a system that deals with how animals receive their oxygen, and not so surprisingly there are many ways different ways animals do this. Humans have an organ called the lungs which helps us inhale oxygen, but fish do not. Fish usually use gills to breathe but there are some exceptions such as the lungfish. The lungfish is one of the only types of fish that have lungs. This is why today we will compare the differences between the lungfish and human respiratory systems. We…

As particles move deeper into the respiratory system, inhaled particles that transverse these barriers continually are filtered down to a size of 1-5 micrometers. The nasal cavity begins the filtration process. It contains physical barriers that can filter particles down to 15 mircons. The…

The oxygen is taken to the muscles during exercise as a result of the circulatory and respiratory systems working together. The heart, blood and the lungs are the…
