Which of the following events can be measured as systolic blood pressure? a) Atrial contraction b) Ventricular contraction c) Pulse pressure d) Cardiac diastole 2. What are the two main factors that determine blood pressure? a) Cardiac output and peripheral resistance b) Peripheral resistance and blood volume c) Blood volume and pulse pressure d) Pulse pressure and cardiac output 3. Which of the following is associated with the moment-to-moment control of blood pressure? a) The renin-angiotensin system b) Control of blood volume c) The baroreceptor reflex d) The Hering-Breuer reflex
Understand the Problem
The questions are asking about physiological concepts related to blood pressure, specifically what can be measured as systolic blood pressure, factors that determine blood pressure, and mechanisms involved in the control of blood pressure.
Answer
1) Ventricular contraction, 2) Cardiac output and peripheral resistance, 3) Baroreceptor reflex
- Ventricular contraction (b), 2) Cardiac output and peripheral resistance (a), 3) The baroreceptor reflex (c)
Answer for screen readers
- Ventricular contraction (b), 2) Cardiac output and peripheral resistance (a), 3) The baroreceptor reflex (c)
More Information
Systolic blood pressure is primarily due to ventricular contraction. Blood pressure is determined by cardiac output and peripheral resistance. The baroreceptor reflex provides rapid changes to maintain stable blood pressure.
