Quick Answer: What Physiological Function Does The Systolic Pressure Represent?

There are two pressures measured: (1) the systolic pressure (the higher pressure and the first number recorded), which is the force that blood exerts on the artery walls as the heart contracts to pump the blood to the peripheral organs and tissues, and (2) the diastolic pressure (the lower pressure and the second

What does systolic blood pressure represent physiologically?

Systolic pressure refers to the maximum pressure within the large arteries when the heart muscle contracts to propel blood through the body. Diastolic pressure describes the lowest pressure within the large arteries during heart muscle relaxation between beating.

What is the function of systolic blood pressure?

Your systolic blood pressure is the top number on your reading. It measures the force of blood against your artery walls while your ventricles — the lower two chambers of your heart — squeeze, pushing blood out to the rest of your body.

What does systolic pressure measure specifically?

Systolic blood pressure (the first and higher number) measures pressure inside your arteries when the heart beats. Diastolic blood pressure (the second and lower number) measures the pressure inside the artery when the heart rests between beats.

What are the two major physiological factors that systolic BP measures?

Systolic blood pressure is mainly determined by:

• Arterial elastance and compliance (major influence)
• Stroke volume, insofar as it affects elastance and compliance.
• Total arterial peripheral resistance.

What is the physiology of blood pressure?

blood pressure, force originating in the pumping action of the heart, exerted by the blood against the walls of the blood vessels; the stretching of the vessels in response to this force and their subsequent contraction are important in maintaining blood flow through the vascular system.

What is the significance of systolic and diastolic blood pressure?

Systolic blood pressure indicates the amount of pressure being exerted on the walls of your arteries when your heart beats. Diastolic blood pressure indicates the amount of pressure being exerted on the walls of your arteries in between heartbeats.

What does the systolic blood pressure reading represent quizlet?

The top number refers to the amount of pressure in your arteries during the contraction of your heart muscle. This is called systolic pressure. The bottom number refers to your blood pressure when your heart muscle is between beats. This is called diastolic pressure.

Where does systolic blood pressure occur?

Systolic: The blood pressure when the heart is contracting. It is specifically the maximum arterial pressure during contraction of the left ventricle of the heart. The time at which ventricular contraction occurs is called systole.

What is the significance of blood pressure measurement?

It’s important to get an accurate blood pressure reading so that you have a clearer picture of your risk for heart disease and stroke. A reading that says your blood pressure is lower than it actually is may give you a false sense of security about your health.

What causes korotkoff?

Korotkoff sounds are produced underneath the distal half of the blood pressure cuff. The sounds appear when cuff pressures are between systolic and diastolic blood pressure, because the underlying artery is collapsing completely and then reopening with each heartbeat.

Why is blood pressure important for physiological function and survival?

It is an important force because oxygen and nutrients would not be pushed around our circulatory system to nourish tissues and organs without blood pressure. Blood pressure is also vital because it delivers white blood cells and antibodies for immunity, and hormones such as insulin.

What is are the physiological purposes of Vasoreflexes?

Two physiological purposes vasoreflexes serve are? Raising or lowering blood pressure throughout the body, and selectively modifying the perfusion of a particular organ and rerouting blood from one region to another.

What is BP anatomy and physiology?

Blood pressure is the force that blood exerts upon the walls of the blood vessels or chambers of the heart. The components of blood pressure include systolic pressure, which results from ventricular contraction, and diastolic pressure, which results from ventricular relaxation.
