The Structure of a Heart with Transposition of the Great Arteries (TGA) 大动脉转位(TGA)心脏的结构 In transposition, the pulmonary artery and the aorta are switched, or transposed. So they come off the opposite pumping chamber. What that means is that the blue blood comes back to the right atrium, to the right ventricle.大动脉转位是肺动脉和主动脉位置互换或换位。们来自对侧的泵血腔。这表示缺氧血液流回右心房,再到右心室。 But now, instead of going to the lungs, it goes back out to the body. So you have blue blood going in a circle. It never picks up oxygen.但是现在,它没有进入肺,而是流回身体。所以,缺氧血液循环流动。它从不与氧气结合。 Oxygenated blood from the lungs then returns to the left side of the heart, comes from the left side of the heart out to the pulmonary artery, goes to the lungs in a separate circulation.来自肺的含氧血液随后返回心脏左侧,从心脏左侧流出,进入肺动脉,在单独的循环中进入肺。 This creates what we call a "parallel circulation."这就产生了我们所说的“平行循环”。 相关单词学习
