Question

Which valve sep arates the left atrium from the left ventricle? a. mitral b. tricuspid c. pulmonary d. aortic

Short answer

Answer: (a) Mitral valve

Step-by-step solution

Review the structure of the human heart

In order to answer this question, it is important to have a good understanding of the basic structure of the human heart. The heart is divided into four chambers: the left atrium, the left ventricle, the right atrium, and the right ventricle. Blood flows between these chambers through various valves, which ensure that blood moves in the correct direction.

Identify the four heart valves

There are a total of four valves in the human heart, each with a specific location and function: a. Mitral valve (also known as the bicuspid valve) - located between the left atrium and the left ventricle b. Tricuspid valve - located between the right atrium and the right ventricle c. Pulmonary valve - located between the right ventricle and the pulmonary artery d. Aortic valve - located between the left ventricle and the aorta

Select the appropriate valve

Now that we have identified the location and function of each valve, we can easily select the valve that separates the left atrium from the left ventricle: a. Mitral valve (also known as the bicuspid valve) - located between the left atrium and the left ventricle

Conclusion

The correct answer to the question "Which valve separates the left atrium from the left ventricle?" is (a) the mitral valve.
