Circulatory System Flashcards
1
Q
Heart Rate
A
How many times your heart beats per minute.
2
Q
Stroke Volume
A
Volume of blood pumped from the left ventricle per beat.
3
Q
Cardiac Output
A
Amount of blood pumped by the heart per minute.
4
Q
Short Term Effects of Exercise
A
1) Heart rate, stroke volume and cardiac output all increase
2) Body temperature increase so heat can be lost by radiation (vasodilation)
5
Q
Long Term Effects of Exercise
A
1) Resting heart rate decreases (bradycardia)
2) Cardiovascular muscles will strengthen meaning endurance is better and will increase stroke volume
3) Heart more effective
4) Heart will get bigger (hypertrophy)
5) Better ability to tolerate lactic acid
