Air is conducted through smaller and smaller bronchioles for about 15-20 generations, and collectively they're known as conducting bronchioles, receiving O2 from bronchial arteries.

Plaque building up in the coronary arteries, so the ones that transport oxygen-rich blood around the heart, can over time cause a blood clot to form, which cuts off some of the heart muscle and causes it to die.

斑块在冠状动脉中堆积，所以将富含氧气的血液运送到心脏周围的冠状动脉，随着时间的推移，会导致血块的形成，从而切断分心肌，导致心肌死亡。

Sexual arousal triggers the parasympathetic reflex that causes arterioles in the external genitalia to dilate and fill with blood, which is actually one of the only times the parasympathetic system controls any arteriole action.

性唤起触发副交感神经反射，导致外生殖器中的小动脉扩张并充满血液，实际上是副交感神经系统控制任何小动脉动作的唯一时间之一。

Many scientists believe oxidized cholesterol to be the real problem as it initiates the process leading to the buildup of plaque in the arteries.

许多科学家认为，被氧化的胆固醇才是问题所在，因为它会导致血小板在动脉中堆积。

This usually occurs in the deep veins of the legs or in the pulmonary arteries that carry deoxygenated blood from the heart to the lungs.

经发生在腿的深静脉或从心脏通往肺、携带缺氧血的肺动脉中。

The surface of the brain is supplied by numerous arteries in the subarachnoid space that provides oxygen rich blood to the brain.

The researchers also tested to see whether calcium, formed in the arteries of the heart. Calcium build-up can lead to heart attacks.

研究者还化验了心脏动脉中是否有钙形成，钙累积可导致心脏病。

They carefully fed the Merci device into an artery. They guided it up to the affected area of the brain.

他们小心翼翼地把血栓拔除器放进动脉中。然后，他们把血栓拔除器放到大脑受影响的区域。

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

水的存留就会使得动脉中的血液量变多，使血管更充盈，最终会导致高血压。

There's evidence that people with microplastics in particular arteries can be more likely to die of heart disease.

The blood in the arteries is under a lot of pressure because it needs to reach every little nook and cranny of the body.

动脉中的血液处于大量压力之下，因为它需要到达身体的每一个角落和缝隙。

In this form, the great arteries still connect to the wrong ventricle, but it's just that the ventricles are the one's that switch places along with their atrioventricular valves.

在种构造中，大动脉仍然连接着错误的心室，只是心室和房室瓣是一起交换位置的。

This is because the part of the occipital lobe in charge of the macula gets blood from both the posterior cerebral artery as well as the medial cerebral artery.

是因为负责黄斑功能的枕叶分同时由大脑后动脉和大脑中动脉供血。

Plus, if you have cholesterol plaques in your arteries, then you probably have them in your coronary arteries, which carry oxygen and nutrients to the heart muscle itself.

另外，如果你的动脉中有胆固醇斑块，那么你的冠状动脉中可能有胆固醇斑块，将氧气和营养输送到心肌本身。

Most neural responses like this use baroreceptors, special nerve endings found in the carotid arteries, the aorta, and other larger arteries in the neck.
