Human Anatomy Worksheets and Study Guides - Free Printable

Let's solve this step-by-step. This is a human heart labeling and function worksheet. We need to:

1. Label the parts of the heart in the diagram.
2. Color the parts:
- Red for oxygenated blood
- Purple or deep red for deoxygenated blood
3. Complete the chart with:
- Whether the structure carries oxygenated or deoxygenated blood
- Its function

🔹 Step 1: Labeling the Heart Diagram

Here are the labeled parts based on standard anatomy (from top to bottom, left to right):

From the top right, going clockwise:

1. Superior Vena Cava → brings deoxygenated blood from upper body
2. Inferior Vena Cava → brings deoxygenated blood from lower body
3. Pulmonary Artery → carries deoxygenated blood to lungs
4. Pulmonary Veins (usually 4) → carry oxygenated blood from lungs to heart
5. Aorta → main artery carrying oxygenated blood to body
6. Right Atrium → receives deoxygenated blood from vena cavae
7. Right Ventricle → pumps deoxygenated blood to lungs via pulmonary artery
8. Left Atrium → receives oxygenated blood from pulmonary veins
9. Left Ventricle → pumps oxygenated blood to body via aorta

Now, label the blanks accordingly.

> Note: The image has 8 labels pointing to structures. Based on typical diagrams:
>
> - Top left: Superior Vena Cava
> - Bottom left: Inferior Vena Cava
> - Middle left: Right Atrium
> - Lower left: Right Ventricle
> - Upper right: Aorta
> - Middle right: Pulmonary Artery
> - Upper middle right: Pulmonary Veins
> - Lower right: Left Atrium

But since it’s a simplified diagram, we’ll use the most common labeling pattern.

Let’s assume the lines point to:

1. Superior Vena Cava
2. Inferior Vena Cava
3. Right Atrium
4. Right Ventricle
5. Pulmonary Artery
6. Pulmonary Vein
7. Left Atrium
8. Left Ventricle
9. Aorta

Wait — there are 8 blank boxes, so likely these are the main vessels and chambers:

- Superior Vena Cava
- Inferior Vena Cava
- Right Atrium
- Right Ventricle
- Pulmonary Artery
- Pulmonary Vein
- Left Atrium
- Left Ventricle
- Aorta

But only 8 boxes? Let's count:

There are 8 boxes around the diagram. Likely:

1. Superior Vena Cava (top left)
2. Inferior Vena Cava (bottom left)
3. Right Atrium (middle left)
4. Right Ventricle (lower left)
5. Pulmonary Artery (upper right)
6. Pulmonary Vein (middle right)
7. Left Atrium (upper right)
8. Left Ventricle (lower right)
9. Aorta (top right)

Wait — actually, 9 structures but only 8 boxes?

Looking at the image layout (based on common versions), it's likely:

- 8 labels total:
1. Superior Vena Cava
2. Inferior Vena Cava
3. Right Atrium
4. Right Ventricle
5. Pulmonary Artery
6. Pulmonary Vein
7. Left Atrium
8. Left Ventricle
9. Aorta

But only 8 boxes shown? Hmm.

Actually, looking closely at the diagram, there are 8 arrows pointing to structures. Most likely:

- Top left: Superior Vena Cava
- Bottom left: Inferior Vena Cava
- Middle left: Right Atrium
- Lower left: Right Ventricle
- Top right: Aorta
- Upper right: Pulmonary Artery
- Middle right: Pulmonary Vein
- Lower right: Left Atrium
- Bottom right: Left Ventricle

Wait — that’s 9.

Possibly one box is missing, or some are grouped.

But in many versions of this worksheet, the aorta and pulmonary artery are both labeled separately.

Let’s go by the chart below, which includes:

- Vena cava (singular, but refers to both superior and inferior)
- Aorta
- Pulmonary Artery
- Pulmonary Vein
- Right Atrium
- Right Ventricle
- Left Atrium
- Left Ventricle

So the 8 structures to label are:

1. Vena cava (either superior or inferior — usually both are shown, but labeled as "Vena cava")
2. Aorta
3. Pulmonary Artery
4. Pulmonary Vein
5. Right Atrium
6. Right Ventricle
7. Left Atrium
8. Left Ventricle

We can now proceed.

🔹 Step 2: Color Coding

- Oxygenated blood (color in RED):
- Pulmonary Veins
- Left Atrium
- Left Ventricle
- Aorta

- Deoxygenated blood (color in PURPLE/DEEP RED):
- Vena cava (superior & inferior)
- Right Atrium
- Right Ventricle
- Pulmonary Artery

> Remember: The pulmonary artery carries deoxygenated blood to the lungs; the pulmonary vein carries oxygenated blood from the lungs.

🔹 Step 3: Complete the Chart

| Structure | Oxygenated/Deoxygenated Blood | Function |
|---------|-------------------------------|----------|
| Vena cava | Deoxygenated | Carries deoxygenated blood from the body to the right atrium |
| Aorta | Oxygenated | Carries oxygenated blood from the left ventricle to the rest of the body |
| Pulmonary Artery | Deoxygenated | Carries deoxygenated blood from the right ventricle to the lungs |
| Pulmonary Vein | Oxygenated | Carries oxygenated blood from the lungs to the left atrium |
| Right Atrium | Deoxygenated | Receives deoxygenated blood from the vena cava and pumps it into the right ventricle |
| Right Ventricle | Deoxygenated | Pumps deoxygenated blood to the lungs via the pulmonary artery |
| Left Atrium | Oxygenated | Receives oxygenated blood from the pulmonary veins and pumps it into the left ventricle |

> Note: The Left Ventricle is not in the table, but it should be included if there was a row for it. But the chart stops at Left Atrium.

Wait — let's check the table again:

It lists:

- Vena cava
- Aorta
- Pulmonary Artery
- Pulmonary Vein
- Right Atrium
- Right Ventricle
- Left Atrium

No Left Ventricle — that’s odd. But perhaps it's implied.

But based on what’s given, we complete the seven rows.

Let’s fill them:

✔ Final Completed Chart:

| Structure | Oxygenated/Deoxygenated Blood | Function |
|---------|-------------------------------|----------|
| Vena cava | Deoxygenated | Receives deoxygenated blood from the body and delivers it to the right atrium |
| Aorta | Oxygenated | Carries oxygenated blood from the left ventricle to the systemic circulation |
| Pulmonary Artery | Deoxygenated | Transports deoxygenated blood from the right ventricle to the lungs |
| Pulmonary Vein | Oxygenated | Returns oxygenated blood from the lungs to the left atrium |
| Right Atrium | Deoxygenated | Receives deoxygenated blood from the vena cava and pumps it into the right ventricle |
| Right Ventricle | Deoxygenated | Pumps deoxygenated blood to the lungs through the pulmonary artery |
| Left Atrium | Oxygenated | Receives oxygenated blood from the pulmonary veins and passes it to the left ventricle |

> Note: The Left Ventricle is missing from the chart, but it’s a key chamber. If you have space, add it:
>
> - Left Ventricle – Oxygenated – Pumps oxygenated blood into the aorta to supply the body.
