The heart is a beating muscle that pumps oxygen-rich blood to the body through a network of arteries and veins. What we commonly call "blood pressure" is the measurement taken when the heart's left ventricle contracts, and blood is forced through the arteries. As the blood travels from the heart, it exerts pressure against the walls of the arteries. This is referred to as blood pressure.
心臟是一個肌性（器官），將富含氧氣的血液通過動靜脈網(wǎng)泵到全身。我們通常所說的血壓測的是左心室收縮將血液射入動脈時的血壓。當(dāng)血液從心臟射出后，血液對血管壁施加壓力。這就是血壓。
Blood pressure is used to evaluate the force and amount of blood being pumped from the heart as well as the flexibility and condition of the arteries.
血壓被用來評估從心臟射出的血液的量和力度，也用來評估動脈的彈性和健康狀況。
There are two components of a blood pressure measurement. The first is the systolic pressure, which is recorded when blood pressure is at its maximum during contraction of the left ventricle. The second component is diastolic pressure. This measurement is obtained when the blood pressure is at its lowest point when the heart is at rest between beats.
血壓的測量包含兩個內(nèi)容。第一是收縮壓的測量。左心室收縮時當(dāng)血壓達(dá)到最高值時測得收縮壓。第二是舒張壓的測量。心臟在心動周期休息時當(dāng)血壓達(dá)到最低值時測得舒張壓。
