**Labeling Pre-Lab: Valves of the Heart**

**Image Description:**

The image displays an anatomical model of the heart from an anterior view, showcasing its internal structures and major valves.

- **Labels and Structures:**
  - **A**: This label points to the aortic valve, which regulates blood flow from the left ventricle into the aorta.
  - **B**: This label indicates the pulmonary valve, which controls blood flow from the right ventricle into the pulmonary artery.
  - **C**: This label identifies the tricuspid valve, situated between the right atrium and right ventricle, ensuring one-way blood flow.
  - **D**: This label marks the mitral valve, located between the left atrium and left ventricle, facilitating proper blood flow.

**Diagrams:**

The model demonstrates the heart's internal anatomy with a focus on the valves, illustrating their positions and roles in directing blood flow through the heart chambers and into major arteries. Each labeled part highlights specific valves critical for maintaining circulatory efficiency.
