Examples. We could go on and on with great examples of theme, but we won't-I promise. Let's just look at three examples and analyze what gives depth and meaning to these pieces of literature. Take Golding's The Lord of the Flies, for example. We know that Golding taught in a boys' school and later fought in WWII.
The main artery splits into the left pulmonary artery and the right pulmonary artery, each of which directs the blood to the corresponding lung. Along with the umbilical arteries, these are the sole arteries in the body that transport oxygen-depleted blood. The umbilical arteries are located in the uterus.
From lungs, the blood flows into left atrium via pulmonary veins. Finally, the blood in the left atrium is passed into left ventricle and is pumped into aorta which supplies it to the whole body. The most important function of pulmonary veins is to transport oxygen rich blood into the heart.
