Question

Explain three effect of exercise of respiratory system 2

Answer 1

$\huge \bf \underline \red{answer} \:$

Would be increased use of oxygen (because muscles will require more oxygen in order to work) for heart to supply enough oxygen it has to increase its rate and stroke volume, so cardiac output will be high enough for all systems to get oxygen. Because body systems takes oxygen and gives carbon dioxide, lungs will have to work harder in order to remove carbon dioxide from blood and replace it with oxygen, so it will make breathing rate higher than normal.
