Mitralklappe

The video tutorial explains the anatomy and function of heart valves, focusing on the mitral valve. It describes how the mitral valve, located between the left atrium and ventricle, ensures unidirectional blood flow. The mitral valve's structure, including its leaflets and associated muscles, is detailed. The video contrasts the mitral valve with the tricuspid valve and explains the mitral valve's role during systole and diastole. The tutorial also covers how heart valve function is influenced by pressure changes in the heart chambers.

What is the primary function of the mitral valve in the heart?

• To pump blood into the lungs

• To regulate heart rate

• To oxygenate the blood

• To ensure blood flows in one direction

Where is the mitral valve located in the heart?

• Between the right atrium and right ventricle

• Between the left atrium and left ventricle

• Between the left ventricle and aorta

• Between the right ventricle and pulmonary artery

How many leaflets does the mitral valve have?

• One

• Two

• Three

• Four

What is the role of the papillary muscles in relation to the mitral valve?

• To pump blood through the valve

• To open the valve during systole

• To close the valve during diastole

• To prevent the valve leaflets from inverting

During which phase of the cardiac cycle does the mitral valve prevent backflow of blood?

• Diastole

• Systole

• Atrial contraction

• Ventricular filling
