− | + | The Frank-Starling mechanism describes how the [[cardiac]] Ejection volume depends on the changes of pulse, [[preload]] and [[postload]]. If, for example, a person stands up, the preload is reduced in the short term, which is automatically answered with a lower pumping capacity. However, if, for example, physical exercises lead to a higher [[venous]] supply, i.e. more venous blood in front of the [[atrium, atrium|aphoria]], the heart reacts accordingly with a stronger [[ejection performance]]. | |
