What are the components, and their functions, used to measure blood pressure

A sphygmomanometer has three parts: a cuff that can be inflated with air, a pressure meter (manometer) for measuring air pressure in the cuff, and. a stethoscope for listening to the sound the blood makes as it flows through the brachial artery (the major artery found in your upper arm)

Explanation:

when the displaced particles are perpendicular to the direction the wave travels, is called a transverse wave, whereas in longitudinal wave the displace practices are parallel to the direction of the wave.

in the given image:

first image shows - longitudinal wave

second image shows - transverse wave

third image shows - longitudinal wave

fourth image shows - longitudinal wave

since there are no options posted i'll give you a few examples.
