Blood Pressure Regulation Quiz

Blood Pressure and Cardiac Output

• The maximum pressure in the arteries during one heartbeat is known as systolic pressure.
• The minimum pressure in the arteries between two heartbeats in the cardiac cycle is known as diastolic pressure.
• Blood pressure can be calculated using the formula: Blood Pressure = Cardiac Output (CO) x Systemic Vascular Resistance (SVR).
• Blood pressure is measured in units of millimeters of mercury (mmHg).
• Cardiac output can be increased through various mechanisms, such as increasing heart rate or increasing the volume of blood pumped by the heart with each beat.
• The role of blood pressure in the body is to ensure that oxygen and nutrients are delivered to tissues and organs.
• Systolic pressure represents the force exerted by the blood on the walls of the blood vessels when the heart beats.
• The unit of measurement for blood pressure is millimeters of mercury (mmHg).
• The force of blood pushing against the walls of blood vessels is created by the contraction of the heart, which pumps blood through the circulatory system.
