When the mitral valve opens, from where does blood flow?

From the left ventricle to the left atrium
From the left atrium to the left ventricle
From the right atrium to the left ventricle
From the right ventricle to the lungs

The correct answer is: From the left atrium to the left ventricle

When the mitral valve opens, blood flows from the left atrium to the left ventricle. This is the correct sequence in the cardiac cycle. The mitral valve, which is located between the left atrium and the left ventricle, serves the crucial function of allowing blood to move in one direction during the heart's filling phase known as diastole. In this phase, the left atrium receives oxygen-rich blood from the lungs via the pulmonary veins. As the left atrium fills with blood, the pressure within it increases, prompting the mitral valve to open. This allows the blood to flow passively into the left ventricle, preparing it for the next phase of the cardiac cycle when the ventricle will contract and pump blood out to the rest of the body. Understanding the anatomy and function of the heart valves is key to grasping how blood circulates through the heart. The mitral valve's role is critical in ensuring that blood flows efficiently and prevents backflow, which is essential for maintaining proper circulation and oxygenation of the blood.
