Study Notes
Major Vessels
- Superior Vena Cava: Drains deoxygenated blood from the upper body into the right atrium.
- Inferior Vena Cava: Drains deoxygenated blood from the lower body into the right atrium.
- Right Pulmonary Artery: Transports deoxygenated blood from the right ventricle to the right lung for oxygenation.
- Left Pulmonary Artery: Carries deoxygenated blood from the right ventricle to the left lung.
- Pulmonary Trunk: Main vessel splitting into the right and left pulmonary arteries, originating from the right ventricle.
- Aortic Arch: Curved segment of the aorta that distributes oxygenated blood to the body.
- Ascending Aorta: The portion of the aorta that rises from the heart, supplying blood to the coronary arteries.
- Descending Aorta: Carries oxygenated blood down through the thorax and into the abdomen.
Valves
- Pulmonary Valve: Located between the right ventricle and pulmonary trunk, prevents backflow into the ventricle.
- Aortic Valve: Positioned between the left ventricle and the aorta, ensures unidirectional flow of blood to the body.
- Tricuspid Valve: Situated between the right atrium and right ventricle, has three leaflets that prevent backflow.
- Bicuspid/Mitral Valve: Between the left atrium and left ventricle, featuring two leaflets that maintain directional blood flow.
Chambers of the Heart
- Right Atrium: Receives deoxygenated blood from the superior and inferior vena cavae.
- Left Atrium: Collects oxygenated blood from the lungs via the pulmonary veins.
- Right Ventricle: Pumps deoxygenated blood to the lungs for oxygenation through the pulmonary arteries.
- Left Ventricle: Responsible for pumping oxygenated blood to the entire body via the aorta.
Structural Components
- Septum: The wall dividing the right and left sides of the heart, preventing mixing of oxygenated and deoxygenated blood.
- Chordae Tendineae: Fibrous cords connecting the valves to the papillary muscles, preventing valve inversion during contraction.
- Apex: The pointed end of the heart, located at the bottom of the left ventricle.
Additional Vessels
- Right Pulmonary Arteries: These are the branches of the right pulmonary artery leading to the right lung.
- Left Pulmonary Veins: Transport oxygenated blood from the lungs back to the left atrium.
- Brachiocephalic Trunk: Major artery that branches into the right common carotid and right subclavian arteries.
- Left Common Carotid Artery: Supplies blood to the left side of the head and neck.
- Left Subclavian Artery: Provides blood to the left arm and parts of the thorax.
