Respiratory Mechanics - VentilationFunctions of Respiratory System:Bring in oxygen: fuels cell metabolic activity.Release carbon dioxide: rids body of metabolic waste.Regulate blood pH: via regulation of blood oxygen and carbon dioxide concentrations.Three major components:1. Muscular and skeletal components of the chest wall: the "pump".2. Alveoli = interfaces for gas exchange ("gas exchanger").3. Areas of the brain that stimulate respiratory function (the controller").Boyle's Law and The Respiratory System:Boyle's law describes the relationship between the pressure and volume of a gas → dictates the mechanics of respiration.Boyle's Law Equation: (P1)(V1) = (P2)(V2) Pressure and volume of a gas are inversely related (assume temperature is constant).//d1j63owfs0b5j3.cloudfront.net/media/image/1716485357105.png.Changes in altitude & atmospheric pressure:To show Boyle's law in a real-world example, draw a mountain and then draw a balloon at the base of it. The base of the mountain is a region of high pressure.Next, show that you carried the balloon to the top of the mountain; indicate that this is a region of lower pressure.Assuming temperature is constant, at the base and top of the mountain (which, of course it isn't), what happens to the balloon?It expands because its volume increased as the atmospheric pressure decreased. //d1j63owfs0b5j3.cloudfront.net/media/image/1716487527562.pngKey anatomical/mechanical structuresPair of lungs connected by a trachea.//d1j63owfs0b5j3.cloudfront.net/term/images/605-1644263770509.pngLungs sit within a double-walled pleural sac, which separates lungs from thoracic wall.Pleural space, which is the potential space within sac.Sternum and ribs around pleural sac.
