If you find any difficulty in understanding how blood flows through the heart, try to learn using these printable heart flow diagrams. These diagrams show you simple illustration of the blood flow that you can remember easily.
As you can see in the above heart flow diagram, heart consists of various parts. You can check out the parts with the labels to understand the functioning of its different parts. The following is a basic drawing of the heart. Heart pumps pure blood to different parts of the body and then takes the deoxygenated blood from all the parts to the lungs for oxygenation. Note on the drawing are blue arrows which represent un-oxygenated blood flowing into the heart, and red arrows which represent oxygenated blood flowing out of the heart to the organs and brain.
Beginning with the superior and inferior vena cavae and the coronary sinus, the flowchart below summarizes the flow of blood through the heart, including all arteries, veins, and valves that are passed along the way. The blood first enters the right atrium of the heart and then flows into the right ventricle. The tricuspid valve present between the right atrium and right ventricle controls this flow. For better illustration, look at the diagram below.
