Final answer:
The heart valve with two cusps is the mitral valve, also known as the bicuspid valve. It is located between the left atrium and left ventricle. The correct sequence of blood flow through the heart's valves from the vena cava is tricuspid, pulmonary semilunar, bicuspid, and aortic semilunar.
Step-by-step explanation:
The heart valve that has two cusps is known as the mitral valve, which is also sometimes referred to as the bicuspid valve or the left atrioventricular valve. This valve is located at the opening between the left atrium and the left ventricle of the heart. It is structurally distinct from the tricuspid valve, which has three cusps and is located between the right atrium and right ventricle. The mitral valve's two cusps, the anterior medial cusp, and the posterior medial cusp, are attached by chordae tendineae to two papillary muscles that project from the wall of the ventricle, forming an important part of the heart’s structure and function.
Answering the student's question:
- A. Mitral
- B. Aortic
- C. Tricuspid
- D. Pulmonary
The correct answer is A. Mitral.
As for the sequence through which blood flows through the heart's valves from the vena cava, the correct order is: Tricuspid, pulmonary semilunar, bicuspid (another name for the mitral valve), aortic semilunar. Therefore, the correct answer to that question is a. tricuspid, pulmonary semilunar, bicuspid, aortic semilunar.
