4. The two functions of the muscular system are to exert power to move objects. 5. The muscles are attached to the bones to enable them to move to extend the power of the muscle to transfer over a greater distance. Respiratory System 1. the stages of inspiration in the breathing cycle is the diaphragm and intercostals muscles contract lifting the ribs upwards and outwards, then the volume of chest cavity is larger, after this the pressure decreases and finally the air is sucked in. 2. The functions of the respiratory system are to make sure that we are breathing and getting oxygen into our body and helping blood be carried around the body. 4. Strenuous exercise has the effect on your rate of breathing by preventing as much oxygen getting into the lungs and the carbon dioxide level in the blood rises. 5. By the term anaerobic it is meant that energy is produced except that it has no oxygen contained within it. 6. The body works anaerobically during swimming. When someone dives under and is swimming along there is no oxygen entering their body but energy is still there. ...read more.
