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
|
|
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)
