| Description: | Four diagrams showing the hearts and systems of blood circulation. The text that accompanies this illustration describes blood circulation and the heart in different systems. Figure 1 shows 'the most simple form of the heart' and the system of circulation, with a vein (a), an auricle (now called atrium, b), a ventricle (c), and an artery (d). No connection to lungs is shown, and the blood from the veins flows into the atrium, is forced into the ventricle, and is pumped to the rest of the body through the artery, before it rejoins the veins. Figure 2 is a frogs heart. It is similar to figure 1 except that the artery splits and (d) goes to the body and (e) to the lungs. Figure 3 illustrates the system of circulation in a breathing creature. The vena cava (a) carry blood from the body to the right auricle (now the right atrium, b). The blood is then pushed into the right ventricle (c), which pumps it through the pulmonic artery (pulmonary artery, d) to the lungs. This oxygenated blood is then carried through the viens of the lungs (pulmonary veins, e) to the left auricle (left atrium, f). This forces it into the left ventricle (g) which pumps it through the aorta (h) to the rest of the body. Figure 4 shows how both of these systems fit together in the human body. |
