The correct Answer is:
To solve the question regarding the correct arrangement of cardiac valves from the right side to the left side of the heart, we can follow these steps: ### Step-by-Step Solution: 1. **Identify the Valves on the Right Side of the Heart:** - The first valve we encounter on the right side is the **tricuspid valve**. This valve is located between the right atrium and the right ventricle. It allows blood to flow from the atrium to the ventricle. 2. **Next Valve on the Right Side:** - After the right ventricle, the blood is pumped into the pulmonary arteries through the **pulmonary valve** (also known as the pulmonary semilunar valve). This valve prevents backflow of blood into the right ventricle after it has been pumped into the pulmonary arteries. 3. **Identify the Valves on the Left Side of the Heart:** - Moving to the left side, the first valve we encounter is the **bicuspid valve** (also known as the mitral valve). This valve is located between the left atrium and the left ventricle, allowing blood to flow from the atrium to the ventricle. 4. **Next Valve on the Left Side:** - Finally, the blood is pumped from the left ventricle into the aorta through the **aortic valve** (also known as the aortic semilunar valve). This valve prevents backflow of blood into the left ventricle after it has been pumped into the aorta. 5. **Summarize the Arrangement:** - Therefore, the correct arrangement of the cardiac valves from the right side to the left side is: - Tricuspid valve (right atrium to right ventricle) - Pulmonary valve (right ventricle to pulmonary arteries) - Bicuspid valve (left atrium to left ventricle) - Aortic valve (left ventricle to aorta) ### Final Answer: The correct arrangement of cardiac valves from the right side to the left side is: **Tricuspid valve → Pulmonary valve → Bicuspid valve → Aortic valve.**
