Answer 1

Answer: (D)

Blood pressure is the arterial pressure of blood exerted on the walls of arteries with each heartbeat. It is measured from the brachial artery and expressed as systolic pressure/ diastolic pressure (i. e. $120/80mmHg$). Blood pressure is affected by atherosclerosis (caused by deposits if calcium, fats, cholesterol, and fibrous tissue which make lumen narrow). Diastolic pressure is lower than systolic pressure. It refers to as arterial pressure of the systemic circulation
