How does hypertension affect vessels
WebHypertension is abnormally high blood pressure in the arteries, which are the blood vessels that carry blood from the heart to the rest of the body. As the heart beats, it forces blood through the arteries to deliver nutrients and oxygen to the rest of the body.

WebAs shown in Figure 20.2.1, the difference between the systolic pressure and the diastolic pressure is the pulse pressure. For example, an individual with a systolic blood pressure (BP) of 120 mm Hg and a diastolic BP of 80 mm Hg would have a pulse pressure of 40 mmHg. Pulse pressure = systolic BP – diastolic BP.
