impact of excerise on the Cardio-vascular respiratory system
bigger + stronger heart
larger lung capacity
loser blood pressure
more capillaries in the muscles
more red blood cells
Bigger + stronger heart
heart is a muscle - during excerise it adapts and gets bigger and stronger
a bigger and stronger heart = stronger contraction - pump more blood with each beat
resting stroke volume and maximum cardiac output increases
resting heart rate decreases, beats less often
larger lung capacity
diaphragm and muscles in between ribs, get stronger - makes chest cavity larger
volume of alveoli increases
lung capacity increases - breathe in more oxygen into bloodstream
lower blood pressure
regular exercise = veins and arteries get bigger
muscular walls become more elastic
blood pressure falls
more capillaries in muscles
increases blood supply to muscles
they receive more oxygen
more red blood cells
blood carries more oxygen
