Study Notes

Brachiocephalic Trunk

Major artery branching from the aortic arch, supplying blood to the right arm and head.

Superior Vena Cava

Large vein that carries deoxygenated blood from the upper body to the right atrium of the heart.

Right Pulmonary Artery

Transports deoxygenated blood from the right ventricle to the right lung for oxygenation.

Ascending Aorta

Portion of the aorta that rises from the heart, supplying oxygenated blood to the body.

Pulmonary Trunk

Major vessel that splits into the right and left pulmonary arteries, carrying deoxygenated blood to the lungs.

Right Pulmonary Veins

Four veins (two from each lung) returning oxygenated blood from the right lung to the left atrium.

Right Atrium

Upper right chamber of the heart, receiving deoxygenated blood from the body via superior and inferior venae cavae.

Right Atrioventricular Groove

Groove marking the boundary between the right atrium and right ventricle; also known as the atrioventricular sulcus.

Anterior Cardiac Vein

Drains blood from the right ventricle directly into the right atrium, bypassing the coronary sinus.

Right Ventricle

Lower right chamber of the heart, pumping deoxygenated blood into the pulmonary trunk toward the lungs.

Marginal Artery

Artery that provides blood supply along the margin of the heart, formed by the anastomosis of the terminal branches of the right and left coronary arteries.

Small Cardiac Vein

Drains blood from the right ventricle and empties into the coronary sinus, assisting venous return.

Inferior Vena Cava

Large vein carrying deoxygenated blood from the lower body to the right atrium of the heart.

Left Common Carotid Artery

Main artery supplying blood to the left side of the head and neck, arising from the aortic arch.

Left Subclavian Artery

Supplies the left arm and part of the thorax; branches from the aortic arch.

Aortic Arch

Curved portion of the aorta, giving rise to major arteries that supply the head, neck, and arms.

Ligamentum Arteriosum

Fibrous remnant of the ductus arteriosus, a fetal blood vessel that closes after birth.

Left Pulmonary Artery

Carries deoxygenated blood from the right ventricle to the left lung for oxygenation.

Left Pulmonary Veins

Return oxygenated blood from the left lung to the left atrium; there are typically two veins.

Left Atrium

Upper left chamber of the heart, receiving oxygenated blood from the lungs via pulmonary veins.

Circumflex Artery

Branches from the left coronary artery, supplying blood to the lateral and posterior aspects of the left ventricle.

Left Atrioventricular Groove

Groove separating the left atrium from the left ventricle, important for vascular structures.

Left Ventricle

Lower left chamber of the heart, responsible for pumping oxygenated blood to the body via the aorta.

Great Cardiac Vein

Drains blood from the anterior aspect of the heart and empties into the coronary sinus.

Anterior Interventricular Artery

Also known as the left anterior descending artery, supplies blood to the anterior walls of both ventricles.

Apex

The tip or pointed end of the heart, primarily composed of the left ventricle; important in the heart's orientation and function.
