Respiratory system: Minute ventilation is the quantity of oxygen which is taken in by your lungs per minute. When we exercise there is a higher oxygen intake per minute due to a higher breathing rate‚ we will also need more oxygenated blood cells to go round to the muscles in use to help try and prevent muscular injuries. The reason why when minute ventilation increases is positive to an athlete is because there is a higher intake of oxygen and nutrients needed. This will mean that the athlete

body affect the respiratory system. As individuals age‚ bones of the body become thin‚ weak‚ and change shape. The ribcage is affected by this change and can alter a person’s breathing as it becomes unable to expand and contract the way it used to. Muscles in the body also become weak. If the muscle that supports breathing‚ called the diaphragm‚ becomes weak‚ individuals may have difficulty breathing enough air in and out of the body‚ which could not only lower the body’s oxygen level but also remove
