Coronary Circulation Coronary Arteries & Cardiac Veins

The video provides a detailed explanation of coronary circulation, focusing on the aorta, major arteries, coronary arteries, and cardiac veins. It highlights the importance of these vessels in supplying blood to the heart and draining it back to the right atrium. The video uses a schematic approach to simplify the understanding of these complex structures.

What is the primary purpose of the schematic approach to learning coronary circulation?

• To learn about systemic circulation

• To focus on heart diseases

• To simplify understanding of coronary circulation

• To memorize anatomical pictures

Which artery is the first to branch off from the aorta?

• Left subclavian artery

• Right coronary artery

• Left common carotid artery

• Brachiocephalic artery

What does the anterior interventricular artery supply?

• Both ventricles

• Left atrium

• Right atrium

• Only the left ventricle

Which artery is responsible for supplying the left atrium and left posterior ventricle?

• Circumflex artery

• Right marginal artery

• Anterior interventricular artery

• Posterior interventricular artery

What is the first branch of the right coronary artery?

• Anterior interventricular artery

• Right marginal artery

• Left marginal artery

• Circumflex artery

Which artery runs down the posterior interventricular septum?

• Right marginal artery

• Posterior interventricular artery

• Circumflex artery

• Anterior interventricular artery

What is the correct term for the veins that drain the heart?

• Cardiac veins

• Coronary veins

• Pulmonary veins

• Aortic veins

Which cardiac vein is the largest?

• Coronary sinus

• Great cardiac vein

• Small cardiac vein

• Middle cardiac vein

Where does the coronary sinus drain blood into?

• Left atrium
