The Anatomy Of The Heart

This video tutorial makes biology engaging by exploring the anatomy of the human heart. It covers the heart's chambers, valves, and blood flow, explaining the right and left sides, atrioventricular and semilunar valves, and major vessels like the vena cava and pulmonary trunk. The video also delves into the heart's septa and advanced details like chordae tendineae and papillary muscles, emphasizing their roles in preventing backflow. The tutorial concludes with a call to action for viewers to subscribe and access additional resources.

Which chamber of the heart receives deoxygenated blood from the body?

• Left atrium

• Right ventricle

• Right atrium

• Left ventricle

What is another name for the left atrioventricular valve?

• Pulmonary valve

• Tricuspid valve

• Mitral valve

• Aortic valve

Which valve prevents backflow of blood from the aorta into the heart?

• Mitral valve

• Pulmonary valve

• Aortic valve

• Tricuspid valve

What is the function of the superior vena cava?

• Carries blood from the heart to the lungs

• Carries blood from the lungs to the heart

• Carries deoxygenated blood from the body to the heart

• Carries oxygenated blood to the body

Which vessels carry oxygenated blood from the lungs to the heart?

• Vena cava

• Pulmonary arteries

• Pulmonary veins

• Aorta

What is the role of the chordae tendineae in the heart?

• They open the heart valves

• They anchor the heart valves to the papillary muscles

• They separate the left and right ventricles

• They carry blood to the heart

What would happen if the chordae tendineae were absent?

• Blood would flow backward into the atria

• Valves would remain open

• Blood would not reach the lungs

• Heart would stop beating
