Left atrium

This tutorial covers the anatomy and function of the heart's atria, focusing on the left atrium. It explains how the atria facilitate blood circulation, the role of the left atrium in collecting oxygenated blood from the pulmonary veins, and the function of the mitral valve. The video also discusses the blood supply to the left atrium and the significance of the foramen ovale during embryonic development. Additional resources for further learning are provided.

What is the primary function of the atria in the heart?

• To regulate heart rate

• To oxygenate the blood

• To pump blood to the lungs

Which valve is associated with the left atrium?

• Mitral valve

• Pulmonary valve

• Tricuspid valve

• Aortic valve

What is the role of the left circumflex coronary artery?

• To supply blood to the right atrium

• To drain blood from the left atrium

• To supply blood to the left atrium

• To drain blood from the right atrium

What is the foramen ovale?

• A hole in the cardiac wall during embryonic development

• A vein in the left atrium

• A type of heart muscle

• A valve in the left ventricle

What is the oblique vein of the left atrium?

• A vein that supplies the left ventricle

• A vein that arises from the left side of the fetal superior vena cava

• A vein that drains the right atrium
