Resumo de Recurso
Short term effects of exercise (Respiratory)
Minute Volume = Amount of breath in one minute
Expired MV = Amount of air breathed out in one minute
Inspired MV = Amount of air breathed in, in one minute
MV goes up when exercising
Respiratory rate goes up when exercising
TV = Volume of air in one breath x RR
Rest: RR = 12 breaths per min, Volume = 0.5l per breath
Moderate: RR = 30 breaths per min, Volume = 2.5l per breath
Maximal: RR = 48 breaths per min, Volume = 4l per breath
Diffusion
Diffusion is when molecules move from high concentration to low concentration
Gaseous exchange - occurs at the alveoli. Thin walls mean easy diffusion. Oxygen will leave the alveoli and enter the capillaries
Diffusion occurs at the muscles. Capillaries touch the muscles and oxygen will move across into the muscle
