Mitral valve

The video tutorial explains the role of heart valves in the cardiovascular system, focusing on the mitral valve. It covers the anatomy, function, and location of the mitral valve, also known as the bicuspid valve, which is one of the atrioventricular valves. The tutorial describes how the mitral valve is connected to the ventricular walls via the cordi tenderoni and papillary muscles, forming the subvalvular apparatus. It highlights the importance of the mitral valve in preventing backflow during cardiac systole and its contribution to the heart's 'Lub' sound.

What is the primary role of heart valves in the cardiovascular system?

• To store blood

• To increase blood pressure

• To decrease heart rate

• To control the direction and timing of blood flow

What is the mitral valve also known as?

• Aortic valve

• Bicuspid valve

• Pulmonary valve

• Tricuspid valve

Where is the mitral valve located?

• Between the right atrium and right ventricle

• Between the left atrium and left ventricle

• Between the right ventricle and pulmonary artery

• Between the left ventricle and aorta

What prevents the cusps of the mitral valve from inverting into the atria?

• Pulmonary veins

• Aortic pressure

• Ventricular contraction

• Cordi tenderoni and papillary muscles

What sound is associated with the closure of the atrioventricular valves?

• Dub

• Lub

• Thump

• Swoosh
