Linker Ventrikel

The video tutorial provides an in-depth look at the heart's anatomy, focusing on the left ventricle. It explains the heart's structure, including the ventricles and atriums, and the function of the atrio-ventricular and aortic valves. The heart's position in the thorax and the differences between the left and right ventricles are discussed, highlighting the left ventricle's thicker wall due to its role in systemic circulation. The tutorial also covers cardiac output, emphasizing the heart's performance in both average individuals and athletes.

What is the primary function of the atrioventricular valves in the heart?

• To regulate heart rate

• To supply oxygen to the heart muscle

• To separate the ventricles from the atria

• To pump blood into the ventricles

During which phase does the mitral valve close?

• Diastole

• Systole

• Atrial contraction

• Ventricular filling

Where is the apex of the heart typically located?

• At the level of the third rib

• At the level of the fifth space between ribs

• At the base of the heart

• Near the right atrium

Why is the wall of the left ventricle thicker than that of the right?

• It is closer to the heart's apex

• It pumps blood to the lungs

• It stores more blood

• It requires more strength to pump blood into the systemic circulation

What is the average cardiac output of a healthy adult at rest?

• 5 liters per minute

• 10 liters per minute

• 15 liters per minute

• 3 liters per minute
