Document Summary

If there is greater stiffness, there is higher frequency. Equations: wavelength = v/f (wavelength = velocity/frequency, frequency f = 1/t, period t = 1/f. Breathing: boyle"s law states that pressure and volume have an inverse relationship. Pressure of a gas in a closed container is inversely proportional to the volume of that container. Ic (inspiratory capacity) total amount you can inhale. 60 100% high lung volume: relaxation curve shows that relaxation pressure is positive during (maximum vital capacity) inspiration and it is negative during (low vital capacity/ minimal vital capacity) expiration. When we inhale significantly, lung pressure drops up until a certain point. The pressure rises because there is too much air coming in and the pressure will need to relax and go back to equilibrium. There is positive pressure to get back to the resting state. There is negative pressure when the pressure goes beyond vital capacity.
