FunctionsThe Respiratory | The Circulatory | To get oxygen into the body and to remove Carbon Dioxide out of the body. | To transport nutrients, oxygen and other products as well as dispose of wastes like Carbon Dioxide |
| | Key TermsOxygen Debt: Shortfall of oxygen to the body after maximal effort/ anaerobic exercise, resulting in deep and shallow breathing (Running short distance, very fast, once you stop you breath heavily to gather more oxygen.) | Heart rate: The amount of beats per minute. | Vital Capacity: The maximum amount of air that can be forcibly exhaled after breathing in as much as possible. | Stroke Volume: The amount of blood pumped by the heart in one beat. | Tidal Volume: Amount of air breathed in and or out at rest. | Cardiac Output: The amount of blood pumped by the heart in one minute | | | To get Cardiac Output: Stroke volume TIMES (X) Heart rate, |
| | Breathing 101Mechanism of breathing | What happens when we breath in? | What happens when we breath out? | Lungs are not muscles therefore they can't move on their own accord. They are helped by the diaphragm and the intercostal muscles between the ribs. | INSPIRATION HAPPENS | EXPIRATION HAPPENS | | | Our diaphragm pulls down | Our diaphragm relaxes | | | Our intercostal muscles contract as air pressure is reduced (to make room for all the new air) | Our intercostal muscles relax and the pressure increases in our lungs as the air is forced out (releasing the air like squeezing a balloon) | | | Air is sucked through the tubes into the lungs | Our chest then becomes smaller (as all the air is gone now) | | | Our chest then expends (as air is in it now) |
