During vasoconstriction, the artery gets smaller and offers increased resistance.

在血管收缩程，脉变小，阻力增加。

In the procedure, doctors implanted two small metal mesh stents in a coronary artery to aid bloodflow.

在手术程，医生在冠状脉植入了两个小金属网支架以促进血液。

That water contributes to more blood in the arteries, making them more full, which leads to higher pressures.

水的存留就会使得脉的血液量变多，使血管更充盈，最终会导致高血压。

Can you feel blood moving through the artery?

你能感觉到血液在脉吗？

The blood moving through your arteries.

血液在你的脉。

The second reading is your diastolic blood pressure, which is the pressure in your arteries when the ventricles are relaxed.

第二个读数是你的舒张压，这是心室放松时脉的压力。

The blood spraying from the severed artery in Caravaggio's looks stilted and artificial by comparison.

The average arterial blood pressure during a single cardiac cycle is called the mean arterial pressure (MAP).

单个心周期的平均脉血压称为平均脉压（MAP）。

Therefore, right after ventricular systole occurs, the pressure is passed along and rises in these arteries.

因此，在心室收缩发生后，压力在这些脉传递并上升。
