Cardiovascular System- Transport Of Oxygen And Blood Flashcards
1
Q
Stroke volume
A
Volume of blood pumped out by the heart ventricles in each contraction
2
Q
Diastole phase
A
When the heart relaxes to fill with blood
3
Q
Ejection fraction
A
Percentage of blood pumped out by the left ventricle per beat
4
Q
Starlings law
A
Increased venous return- greater diastolic filling of the heart- cardiac muscle stretched- more force of contraction- increased ejection fraction
5
Q
Cardiac output
A
Volume of blood pumped out by the heart ventricles per minute
6
Q
Cardiac hypertrophy
A
The thickening of the muscular wall of the heart so it becomes bigger and stronger. Comes as a result if regular aerobic training
7
