Learn about how the blood flows through our heart, the organ that pumps and transport blood from and to our body, with the help of these printable heart diagrams. These free and printable Heart Diagrams Blood Flow are available with and without labels. The labeled ones are available in the following images and you can use the unlabeled version for review purposes.
The diagram below summarizes the flow of blood through the heart, including all arteries, veins, and valves that are passed along the way.
Observe in the Heart Diagram Blood Flow above that the human heart is connected with blood vessels that pump blood from and to our body. The blood is pumped into the blood vessels through the heart. Our 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. The blue arrows represent un-oxygenated blood flowing into the heart and the red arrows represent oxygenated blood flowing out of the heart to the organs and brain. You can check out the parts with the labels to understand more about the functions.
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. There are several different blood flow system diagrams, with or without labels.
The diagrams above are for educational review or quiz on blood flow lessons. Print our blood flow through the heart diagrams to help you study more about the function of the heart!
