Interactive worksheet to identify parts of the human heart.

The task is to label the parts of the human heart in the provided diagram. Below is the solution with explanations for each part:

Labeling the Parts of the Human Heart

1. Aorta: The large artery that emerges from the top of the left ventricle and carries oxygenated blood to the body.
- Location: Top center of the heart, emerging from the left ventricle.

2. Pulmonary Artery: The artery that carries deoxygenated blood from the right ventricle to the lungs.
- Location: Emerging from the right ventricle, just below the aorta.

3. Pulmonary Vein: The vein that carries oxygenated blood from the lungs back to the left atrium (auricle).
- Location: Entering the left atrium at the top left side of the heart.

4. Left Auricle (Atrium): The upper chamber on the left side of the heart that receives oxygenated blood from the pulmonary veins.
- Location: Upper left chamber of the heart.

5. Left Ventricle: The lower chamber on the left side of the heart that pumps oxygenated blood into the aorta.
- Location: Lower left chamber of the heart.

6. Right Auricle (Atrium): The upper chamber on the right side of the heart that receives deoxygenated blood from the body via the superior and inferior vena cava.
- Location: Upper right chamber of the heart.

7. Right Ventricle: The lower chamber on the right side of the heart that pumps deoxygenated blood into the pulmonary artery.
- Location: Lower right chamber of the heart.

8. Septum: The muscular wall that separates the left and right sides of the heart.
- Location: The vertical wall dividing the left and right chambers of the heart.

9. Superior Vena Cava: A large vein that returns deoxygenated blood from the upper body to the right atrium.
- Location: Entering the right atrium at the top right side of the heart.

10. Inferior Vena Cava: A large vein that returns deoxygenated blood from the lower body to the right atrium.
- Location: Entering the right atrium at the bottom right side of the heart.

Final Labeling

Here is how the labels should be placed on the diagram:

- Top Center: Aorta
- Just Below Aorta: Pulmonary Artery
- Top Left Side: Pulmonary Vein
- Upper Left Chamber: Left Auricle
- Lower Left Chamber: Left Ventricle
- Upper Right Chamber: Right Auricle
- Lower Right Chamber: Right Ventricle
- Vertical Wall Between Chambers: Septum
- Top Right Side: Superior Vena Cava
- Bottom Right Side: Inferior Vena Cava

Explanation

Each part of the heart has a specific function:
- Atria (Auricles): Receive blood returning to the heart.
- Ventricles: Pump blood out of the heart.
- Arteries: Carry blood away from the heart.
- Veins: Carry blood toward the heart.
- Septum: Ensures that oxygenated and deoxygenated blood do not mix.

By understanding these functions and their locations, you can accurately label the parts of the heart.
