- 23. arterial circle: a complete circle of connecting blood vessels
- 24. valve: guards the bases of the two large arteries leaving the ventricular chambers

- 2. is a rapid heart rate, over 100 beats per minute
- 4. pressure: the pressure in the arteries at the peak of ventricular contraction
- 5. a rapid, uncoordinated quivering of ventricles
- 6. pressure: the pressure the blood exerts against the inner walls of the blood vessels
