#1

The primary function of the respiratory system supplies the oxygen to the blood, maintains the acid base of the blood, ventilates the lungs and excretes carbon dioxide and water vapor.  When we breathe in we inhale oxygen an exhales the carbon dioxide and this is all goes on in the alveoli.  So when we inhale oxygen it enters though our mouth or nose and then goes through the larynx and the trachea. When our diaphragm contracts oxygen is being pulled into the lungs and when the diaphragm relaxes the carbon dioxide is pumped out of the lungs.

When you exercise it causes your heart to pump more blood to meet the demands of an increased work load. Your heart pumps faster and your lungs respire faster and this increases your respiratory rate. After exercising for a while the increased blood flow brings vasodilatory metabolites to the blood vessels around the working muscles. The blood vessels dilate and then there is more blood flow and this decreases the blood pressure and initial heart rate and the heart is not working as hard and the respiratory rate decreases. After stopping exercising your respiratory rate will remain the same because your body has compensated for the increased heart rate changes by dilating the blood vessels to increase flow. If your respiration rate stays high during exercise then this probably means that you are obese, diabetic, asthmatic, or have a serious lung or heart problem. If the respiration rate stayed low after exercise generally this could be normal because your body is trained to do this and you are an athlete or you have low blood pressure.  Usually after exercise it is normal for breathing to be slightly faster or normal depending on how long or how intensely you've have been exercising.
