Coronary Arteries and Veins

The video by Armando Hasudugan explores the coronary arteries and cardiac veins, focusing on the coronary blood supply to the heart. It examines the right and left coronary arteries from both anterior and posterior views, detailing their branches and the areas they supply. The video also covers the cardiac veins, emphasizing their role in returning deoxygenated blood to the right atrium via the coronary sinus. Key veins like the small cardiac vein, middle vein, and great cardiac vein are discussed, along with the unique anterior vein that drains directly into the right atrium.

What is the primary function of coronary arteries?

• To supply blood to the liver

• To supply blood to the lungs

• To supply blood to the heart muscles

• To supply blood to the brain

Which artery branches into the right posterior descending artery?

• Circumflex artery

• Right coronary artery

• Left anterior descending artery

• Left coronary artery

What does the acute marginal artery supply?

• Right ventricle

• Left ventricle

• Right atrium

• Left atrium

Which artery supplies blood to the left atrium and left ventricle?

• Acute marginal artery

• Right coronary artery

• Left anterior descending artery

• Circumflex artery

From the posterior view, which artery wraps around to supply the left atrium?

• Acute marginal artery

• Left anterior descending artery

• Right coronary artery

• Circumflex artery

What is the role of the coronary sinus?

• To drain deoxygenated blood from the heart

• To drain blood from the brain

• To supply blood to the lungs

• To supply oxygenated blood to the heart

Which vein does not join the coronary sinus but drains directly into the right atrium?

• Great cardiac vein

• Small cardiac vein
