Functions
The 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 Terms
Oxygen 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, |

Mechanism 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) |
