Labelled Diagram of Heart
The heart has four parts:
- The top two parts are called auricles.
- The bottom two parts are called ventricles.
- The heart wall has three layers:
- The outside layer is called epicardium.
- The middle layer is called myocardium.
- The inner layer is called endocardium.
- There are four valves in the heart:
- The aortic valve stops blood from flowing back when it moves from the left ventricle to the aorta.
- The mitral valve stops blood from flowing back when it moves from the left atrium to the left ventricle.
- The pulmonary valve stops blood from flowing back when it moves from the right ventricle to the pulmonary artery.
- The tricuspid valve stops blood from flowing back when it moves from the right atrium to the right ventricle.
- Arteries carry oxygen-rich blood from the heart to different body parts. But the pulmonary artery is different; it carries deoxygenated blood to the lungs for cleaning.
- Veins carry impure blood from different body parts back to the heart for oxygenation. But the pulmonary vein carries oxygenated blood to the heart.
