Human Heart Anatomy Worksheet – Label, Color, and Learn Functions

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 into aorta

> Note: The diagram has 8 labels (boxes). Let’s match them:

- Top-left box → Superior Vena Cava
- Middle-left box → Inferior Vena Cava
- Bottom-left box → Pulmonary Artery (or possibly Right Ventricle — depends on arrow)
- But typically:
- Left side (top to bottom): Superior Vena Cava, Inferior Vena Cava, Pulmonary Artery, Right Ventricle
- Right side: Aorta, Pulmonary Veins, Left Atrium, Left Ventricle

But let’s assign based on common layout:

✔ Based on typical diagrams:

| Box Position | Label |
|--------------|-------|
| Top-right | Aorta |
| Middle-right | Pulmonary Vein |
| Bottom-right | Left Ventricle |
| Top-left | Superior Vena Cava |
| Middle-left | Inferior Vena Cava |
| Bottom-left | Pulmonary Artery |
| Bottom-center (arrow pointing to right ventricle) | Right Ventricle |
| Middle-center (pointing to right atrium) | Right Atrium |

So the labels should be:

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

Wait — there are 8 boxes and 9 structures? Let’s count the arrows.

Looking closely at the image (based on standard versions), likely:

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

And the pulmonary veins might be grouped together (often shown as two or four vessels).

So final labels (from top to bottom, left to right):

- Top-left: Superior Vena Cava
- Middle-left: Inferior Vena Cava
- Bottom-left: Pulmonary Artery
- Bottom-center: Right Ventricle
- Middle-center: Right Atrium
- Top-right: Aorta
- Middle-right: Pulmonary Veins
- Bottom-right: Left Ventricle

Wait — that doesn’t align. Let’s use a better method.

Actually, in most such diagrams:

- The large vessel at the top (coming from head/upper body) → Superior Vena Cava
- The large vessel at the bottom (from lower body) → Inferior Vena Cava
- The vessel going from heart to lungs (on right side) → Pulmonary Artery
- The vessels coming from lungs to heart (on left side) → Pulmonary Veins
- The main artery leaving heart (curved up) → Aorta
- The chambers:
- Right side: Right Atrium, Right Ventricle
- Left side: Left Atrium, Left Ventricle

So the 8 labels are:

1. Superior Vena Cava (top left)
2. Inferior Vena Cava (bottom left)
3. Pulmonary Artery (right side, from right ventricle)
4. Right Atrium (top right chamber)
5. Right Ventricle (bottom right chamber)
6. Left Atrium (top left chamber)
7. Left Ventricle (bottom left chamber)
8. Aorta (top curved vessel)

Wait — but Pulmonary Veins are missing? That’s odd.

Ah — perhaps one of the top vessels on the left is Pulmonary Vein?

Yes! On the left side, there are usually two pulmonary veins entering the left atrium.

So likely:

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

But that still misses Left Atrium.

Wait — maybe the label for "Left Atrium" is missing?

No — probably the eight boxes are meant for:

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

And the Pulmonary Veins are not labeled separately? Or maybe one of the boxes points to them.

Looking at standard versions of this worksheet, it's common that:

- One box points to Pulmonary Veins (plural)
- Another to Pulmonary Artery
- So likely:

✔ Final Label Assignments (based on arrow positions):

| Arrow Position | Label |
|----------------|--------|
| Top-left (large vessel) | Superior Vena Cava |
| Middle-left (large vessel) | Inferior Vena Cava |
| Bottom-left (vessel from heart to lungs) | Pulmonary Artery |
| Middle-center (chamber on right) | Right Atrium |
| Bottom-center (chamber on right) | Right Ventricle |
| Top-right (curved vessel) | Aorta |
| Middle-right (vessel from lungs to heart) | Pulmonary Vein |
| Bottom-right (chamber on left) | Left Ventricle |

Wait — Left Atrium is missing!

Ah — so likely the box pointing to the top-left chamber (on the left side) is Left Atrium.

So reassign:

Let’s assume:

- Top-left: Superior Vena Cava
- Middle-left: Inferior Vena Cava
- Bottom-left: Pulmonary Artery
- Top-right: Aorta
- Middle-right: Pulmonary Vein
- Bottom-right: Left Ventricle
- Middle-center (right side): Right Atrium
- Bottom-center (right side): Right Ventricle

Still missing Left Atrium.

Wait — perhaps the box pointing to the top-left chamber is Left Atrium?

But that chamber is on the left side, above the left ventricle.

So if the arrow from the middle-right box points to Left Atrium, then:

- Middle-right box: Left Atrium
- Bottom-right box: Left Ventricle

Then:

- Top-right box: Aorta
- Middle-right box: Left Atrium
- Bottom-right box: Left Ventricle

But what about Pulmonary Veins? They enter the Left Atrium, so likely the arrow pointing to the vessels near the left atrium is Pulmonary Veins.

So the middle-right box might be Pulmonary Veins, not Left Atrium.

This is ambiguous without seeing the exact image.

But since the chart below includes Pulmonary Vein, we must label it.

So let’s go by standard diagram logic:

✔ Correct Labels (assuming 8 boxes):

1. Superior Vena Cava – top-left large vessel
2. Inferior Vena Cava – bottom-left large vessel
3. Pulmonary Artery – vessel from right ventricle to lungs
4. Right Atrium – top chamber on right
5. Right Ventricle – bottom chamber on right
6. Left Atrium – top chamber on left
7. Left Ventricle – bottom chamber on left
8. Aorta – large curved vessel from left ventricle
9. Pulmonary Veins – vessels entering left atrium

But only 8 boxes. So likely Pulmonary Veins are included in one box.

Most likely:

- One box points to the two vessels entering the left atrium → Pulmonary Veins
- Another points to the single vessel from left ventricle → Aorta
- One points to the two vessels from right ventricle → Pulmonary Artery

So final labels:

| Box | Label |
|-----|-------|
| Top-left | Superior Vena Cava |
| Middle-left | Inferior Vena Cava |
| Bottom-left | Pulmonary Artery |
| Top-right | Aorta |
| Middle-right | Pulmonary Veins |
| Bottom-right | Left Ventricle |
| Middle-center | Right Atrium |
| Bottom-center | Right Ventricle |

But Left Atrium is not labeled? That’s strange.

Unless the middle-right box points to Left Atrium, and Pulmonary Veins are unlabeled?

No — the chart includes Pulmonary Vein, so it must be labeled.

So likely:

- Box pointing to the vessels entering the left atrium → Pulmonary Veins
- Box pointing to the chamber above left ventricle → Left Atrium

Therefore, the eight boxes must include:

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

And Pulmonary Veins are not among the 8 labeled parts? But they are in the chart.

Wait — the chart has 8 rows:

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

So 8 items, including Pulmonary Vein.

Therefore, the diagram must have 8 labels, one for each.

So the labeled parts are:

1. Vena cava (both superior and inferior often grouped)
2. Aorta
3. Pulmonary Artery
4. Pulmonary Vein
5. Right Atrium
6. Right Ventricle
7. Left Atrium
8. Left Ventricle

So the 8 boxes correspond to these.

Now, color code:

🔹 Step 2: Color Coding

- Oxygenated blood → Red
- Deoxygenated blood → Purple or dark red

Which parts carry which?

| Structure | Blood Type | Color |
|---------|------------|-------|
| Vena cava (superior & inferior) | Deoxygenated | Purple |
| Aorta | Oxygenated | Red |
| Pulmonary Artery | Deoxygenated | Purple |
| Pulmonary Vein | Oxygenated | Red |
| Right Atrium | Deoxygenated | Purple |
| Right Ventricle | Deoxygenated | Purple |
| Left Atrium | Oxygenated | Red |
| Left Ventricle | Oxygenated | Red |

Note: Pulmonary artery carries deoxygenated blood from heart to lungs; Pulmonary vein carries oxygenated blood from lungs to heart.

🔹 Step 3: Complete the Chart

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

✔ Final Answer Summary

#### 🔹 Labeled Parts (in order of boxes):

Assuming the boxes are arranged as follows:

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

Or alternatively, depending on arrows:

But since Pulmonary Vein is in the chart, one box must point to it.

So likely:

- One box points to Pulmonary Veins (near left atrium)
- One points to Pulmonary Artery
- One to Aorta
- Etc.

But without seeing the exact image, we can't be 100% sure.

However, the chart is clear.
