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.
