1
Q
List 5 ways the Cardiovascular and Respiratory systems adapt/change due to endurance training.
(5 marks) (TIPS)
A
- Increased heart and blood volume
- stroke volume at rest
- taking less breaths
- body can use oxygen more
- lover overall heart rate
2
Q
Explain the pathway of Electrical Conduction System of the heart. (5 Marks) (TIPS)
A
SA node > atrial muscles contract > AV node > bundle of HIS> bundle of branches > purkinje fibers> ventricles contract
