But the arteries have/has/has have a muscular lining which resist/resists/have resisted this pres-
sure, and thus the blood is squeezed out of them into the smaller vessels of the body. Blood
pressure is/has/has been the amount of pressure on the blood as a result of the heart's pumping
and the resistance of the arterial walls.
There has/are/have been two kinds of pressure: maximum and minimum. The maximum pressure
occur/occurs/have occurred when the left ventricle contract/contracts/has contracted; it is called
the systolic pressure. The minimum pressure occur/occurs/has occurred just before the heartbeat

Answer 1

Answer:

But the arteries have have a muscular lining which resist this pressure, and thus the blood is squeezed out of them into the smaller vessels of the body. Blood  pressure is the amount of pressure on the blood as a result of the heart's pumping  and the resistance of the arterial walls.

There are two kinds of pressure: maximum and minimum. The maximum pressure  occurs when the left ventricle contracts; it is called  the systolic pressure. The minimum pressure occurs just before the heartbeat  which follows; it is called the diastolic pressure.

When your doctor checks your blood pressure, he uses an instrument which measures it in terms of a column of mercury, which rise s and falls under the pressure. He reads it in millimetre rather than in inches. The average systolic pressure in a young man is abou t 120 milimetres (about 5 inches) of mercury. The diastolic pressure is about 8  millimetres of mercury. These figures are usually stated as 120/80, or 120 over 80.​
