Structure of Heart
Left Ventricle
This ventricle collects the blood and contracts the same time as the right ventricle. Blood is then passed through the aortic semilumar valve to the aorta.
Aorta
The aorta, the largest artery, carries the blood to the rest of the body. Some of the blood branches off into the coronary artery. The heart itself requires blood to sustain itself; hence, the coronary artery supplies the heart muscle with this necessary oxygen.
Layers of the Heart
Pericardium
Surrounds heart
- A double layered sac often characterized as tough tissue
- Outer layer serves to hold the heart in place support of the heart by attaching to various structures in chest cavities
- The inner layer is also known as the epicardium
- Located directly on top of the heart muscle
