Answer

To determine the correct arrangement of cardiac valves from the right side to the left side of the heart, we need to understand the anatomy of the heart and the function of its valves.

### Step-by-Step Solution:

1. **Identify the Heart Chambers**: The heart consists of four chambers: two atria (upper chambers) and two ventricles (lower chambers). The right atrium receives deoxygenated blood from the body, while the left atrium receives oxygenated blood from the lungs.

2. **Understand the Flow of Blood**: Blood flows from the right atrium to the right ventricle, and then from the right ventricle to the lungs via the pulmonary artery. Blood returns from the lungs to the left atrium, flows into the left ventricle, and is then pumped out to the body through the aorta.

3. **Identify the Valves**:
- **Tricuspid Valve**: Located between the right atrium and right ventricle. It prevents backflow of blood into the atrium when the ventricle contracts.
- **Pulmonary Semilunar Valve**: Located between the right ventricle and the pulmonary artery. It prevents backflow of blood into the ventricle after it has been pumped into the pulmonary artery.
- **Bicuspid (Mitral) Valve**: Located between the left atrium and left ventricle. It prevents backflow of blood into the atrium when the ventricle contracts.
- **Aortic Semilunar Valve**: Located between the left ventricle and the aorta. It prevents backflow of blood into the ventricle after it has been pumped into the aorta.

4. **Arrange the Valves from Right to Left**:
- Starting from the right side, we have the **Tricuspid Valve**.
- Next, we have the **Pulmonary Semilunar Valve**.
- Moving to the left side, we have the **Bicuspid (Mitral) Valve**.
- Finally, we have the **Aortic Semilunar Valve**.

5. **Final Arrangement**: Therefore, the correct arrangement of the cardiac valves from the right side to the left side is:
- **Tricuspid Valve → Pulmonary Semilunar Valve → Bicuspid (Mitral) Valve → Aortic Semilunar Valve**.
