The structures that prevent backflow of blood between the chambers of the heart are:
- Atrioventricular valves
- Ventricoatrial valves
- Ventricoarterial valves
- Atrioarterial valves
Atrioventricular valves
The valsalva manoeuvre:
- Has no effect on blood pressure
- Decreases blood pressure
- Increases blood pressure
- Decreases diastolic pressure
Increases blood pressure
Which of the following is a cardiovascular benefit of aerobic training?

- Higher lactic acid
Improved myocardial contractility
Optimal systolic blood pressure is considered to be:
- 90 mmHg
- 120 mmHg
- 150 mmHg
- 180 mmHg
120 mmHg
The myelin sheath is vital for:
- Sensing heat and pain
- Releasing acetylcholine
- Generating an action potential
- Fast transmission of impulses
Fast transmission of impulses
Calcium release in muscle tissue to stimulate actin and myosin interaction flows from the:
