This vein then carries the blood back into the systemic circulation.

然后，这条静脉将血液运回体循环。

These conducting bronchioles receive oxygenated blood from the bronchial arteries of the systemic circulation.

这些传导性细支气管接受来自体循环的支气管动脉血液；动脉血含氧量丰富。

Now, deoxygenated blood is escaping out to the systemic circulation, and being pumped out to the whole body via the aorta.

这时，含氧少的血液逃到体循环去了，并且通过主动脉泵到全身各部位。

This is because as arterial pressure increases in the systemic circulation, it gets harder for the left ventricle to pump blood out into that hypertensive systemic circulation.

这是因为随着体循环的动脉压力增加，左心室更难泵血进入高压体循环。

This essentially means that d-TGA leads to death unless there is some way for blood between the pulmonary and systemic circulations to mix.

这就意味着，除非有一种方法可以将肺循环和全身循环的血混合，否则d-TGA会导致死亡。

With right-sided failure, blood gets backed up to the body, and so patients have congestion in the veins of the systemic circulation.

右侧心力衰竭时，血液在体内其它组织积聚，因此，病人的体循环静脉会有拥堵状况。

The greater the pulmonary obstruction, the more deoxygenated blood enters the systemic circulation, the more severe the symptoms.

肺动脉梗阻越严重，越多低氧的血进入全身循环，症状越严重。

Total peripheral resistance is defined as the total resistance to flow of blood in the systemic circulation.

总外周阻力是指全身循环中对血液流动的总阻力。

We also learned that total peripheral resistance is the total resistance to flow of blood in the systemic circulation.

我们还了解到，总外周阻力是对全身循环中血液流动的总阻力。

So this trip from the left ventricle of the heart, to the body, and back to the right atrium of the heart is called the systemic circulation.

血液从左心室到身体，再回到心脏的右心房的行程，被称为体循环。

What we don't have is any deoxygenated blood escaping into the systemic circulation and causing a baby to appear cyanotic, so we call this acyanotic, which means " not blue" .

这时不会有缺氧血流入体循环而引起婴儿出现发绀，所以我们称之为不发绀，即无青紫。

From there, the blood is carried around the body through the systemic circulation before returning to the heart and starting the process all over again.

自此，血液通过全身循环被带到全身，然后返回心脏，并重新开始整个过程。

When deoxygenated blood mixes into the systemic circulation, it'll often present as cyanosis, a bluish-purple discoloration of the skin, which can be seen in a baby within the first days after birth.

当无氧血混入体循环，会表现为发绀，一种皮肤变为青紫色的症状，在出生后几天便可发现。
