Answer: The basic unit of structure and function is the CELL.
Explanation: All living organisms are made up of cells. Each cell is specialized in it's structure to support the function it is intended for. Groups of specialized cells make up tissue (also specialized for a particular function), this group of specialized tissue makes up an organ, which forms part of a system, and then part of the organism as a whole.
There is no video but I found an image that has the steps to be put in the correct order. Attached is the image.
In taking the blood pressure of the patient, it is best to put the patient on seated position with his or her arms at heart level. The cuff should be placed at least 2 fingerbreadths above the cubital fossa. In using the stethoscope, it is better to use the bell of the stethoscope rather than the diaphragm as we need to hear low pitched sounds.
The first step after all the preliminary steps are done is to wrap the cuff around the arm just above the elbow. Then place the stethoscope over the brachial artery which is in the medial side of the cubital fossa. Next is to squeeze the bulb and inflate the cuff above the systolic pressure. Next is to slowly release the pressure valve. Record the number when the first Korotkoff sound appears (systolic blood pressure). Then record the number when the last Korotkoff sound disappears (diastolic blood pressure). Lastly, is to deflate the cuff.
