With every heartbeat the arterial blood pressure swings between a maximum and a minimum. What are those two values called?
ADiastolic maximum and systolic minimum
BSystolic maximum and diastolic minimum
CArterial maximum and venous minimum
DAbsolute maximum and gauge minimum
Answer & Solution
Correct answer: B. Systolic maximum and diastolic minimum
1. The pumping action of the heart makes arterial pressure pulsate rather than hold steady.
2. The maximum reached with each beat is the systolic pressure.
3. The minimum between beats is the diastolic pressure.
4. Swapping the two names reverses which one represents the heart's peak output.
5. In a reading quoted as 120 over 80, the first number is systolic and the second diastolic.
