What physiology measures blood pressure?

Blood pressure is traditionally measured using auscultation with a mercury-tube sphygmomanometer. It is measured in millimeters of mercury and expressed in terms of systolic pressure over diastolic pressure.

Is blood pressure a physiological measure?

In addition, blood pressure can be measured by tracking changes in blood volume relative to a constant level of pressure applied to forearm, wrist, or index finger. As a general class of physiological measurement, these techniques are called plethysmography.

What are the two physiological components of blood pressure?

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 …

How is blood pressure measured in the arteries?

In general, an individual’s “blood pressure,” or systemic arterial pressure, refers to the pressure measured within large arteries in the systemic circulation. This number splits into systolic blood pressure and diastolic blood pressure. Blood pressure is traditionally measured using auscultation with a mercury-tube sphygmomanometer.

What kind of device is used to measure blood pressure?

Arterial blood pressure is measured by a sphygmomanometer. This consists of: A rubber bag surrounded by a cuff. A manometer (usually a mechanical gauge, sometimes electronic, rarely a mercury column). An inflating bulb to elevate the pressure.

Why is the regulation of blood pressure important?

Regulation of the blood pressure is a vital physiological process enabling the body to respond to immediately changing demands such as ‘fight or flight’, or resting The physiology of blood

What to know about blood pressure and exercise?

Background This lab will build on the class material we have covered on blood flow and pressure and cardiac contraction. It will also introduce some ideas we still have to cover on control of the cardiovascular system in response to exercise and the electrocardiogram.
