Document Summary
Laws: of pekn 1p90: all or none principle. 1 contracts, they all contract (all or nothing: frank starling law. Stretch of a ventricle controls the contracting force. Contracts more forcefully with systole when greater filling happens during diastole: poiseuille"s law. Think flow rate formula: boyle"s law. Pressure of a gas proportional to its volume. Ex: pressure goes up, volume goes down. Think of high to low air when breathing in and out (atmospheric to alveolar air: dalton"s law. Total pressure of gases = sum of pressure each gas would exert. Relate to 3 gases and partial pressure formulas. Total pressure = 760 (normal atmospheric air changes below sea level/ sky level: henry"s law. Amount of gas that dissolves in water determined by solubility in water and partial pressure in the air. Some gases can dissolve in water better than others. Ex: co2 dissolves easier than o2 (more soluble in water: fick"s law.
