Cardiac Anatomy for Dummies
A Quick and Easy Way to Touch Your Heart
This is the front side of your heart, if you want to make it complicated, it's the ventral side.Notice how the big jagged line runs diagonally down from the top and away from the apex. This is called the ventricular septum.
This is the back side of the heart, or as the doctors say, the dorsal side. On this side, the ventricular septum is running directly through the middle of the heart.
The External Anatomy
This is what the outside of the heart looks like. On it, you can see that there are four main parts; the right atrium, which collects bad blood from the rest of the body and delivers it to the right ventricle, the right ventricle, which collects the bad blood from the right atrium and sends it to the lungs for oxygenation, the left atrium, which collects clean blood from the lungs through the pulmonary vein and sends it to the left ventricle, and lastly, the left ventricle which collects clean blood from the left atrium and sends it to the aorta.
The Top View
This is the top view of the heart. The purple represents the Aorta, which is the largest artery in the body and collects pure blood from the left ventricles and delivers it to the rest of the body. The red represents the pulmonary vein, which brings pure blood to the left atrium from the lungs . The blue represents the vena cava, which brings bad blood into the heart and empties it into the right atrium. The green represents the pulmonary artery, which carries bad blood from the right ventricle to the lungs.
The Internal Anatomy
This is the inside of the heart. Everything is exactly the same as the outside of the heart, but you can see the chambers more clearly than from the outer view. However, on the inside, you can see the two main valves which coordinate the movement of blood between the chambers; the tricuspid valve and the bicuspid/mitral valve. The green represents the mitral valve which regulates the blood flow between the left atrium and left ventricle. The blue represents the tricuspid valve which regulates the blood flow between the right atrium and right ventricle.
The Autopsy Report
This is an autopsy report, it's basically a cause of death form. It's used to identify what the problem was that caused the person or being to pass away.
