The Circulatory System worksheet.Label - ESL worksheet by ... - Free Printable

It looks like you've uploaded an image of a worksheet titled "The Circulatory System", which asks you to label the parts of the circulatory system using the following terms: veins, arteries, vena cava, heart.

Since I can't view images directly, I’ll guide you through how to solve this labeling task based on standard human anatomy. Here's how to approach it:

🔍 Step-by-Step Solution:

#### 1. Identify the Heart
- The heart is located in the center of the chest, slightly to the left.
- It’s the central organ of the circulatory system.
- On the diagram, look for a large, muscular organ near the middle of the torso — this is the heart.
- Label it as "Heart".

#### 2. Locate the Vena Cava
- The vena cava is a large vein that carries deoxygenated blood from the body back to the heart.
- There are two: superior vena cava (from upper body) and inferior vena cava (from lower body).
- These veins enter the top and bottom of the heart.
- Look for large vessels leading into the top (superior) and bottom (inferior) of the heart — label them "Vena Cava".

#### 3. Label the Veins
- Veins carry blood toward the heart.
- They are usually shown as thinner lines than arteries and often go from limbs and organs toward the heart.
- In the diagram:
- Trace lines from arms and legs going upward toward the heart.
- These are veins.
- Label them as "Veins" (you may see multiple small veins).

#### 4. Label the Arteries
- Arteries carry blood away from the heart.
- They typically branch out from the heart to supply oxygen-rich blood to the body.
- Look for lines coming out of the heart and spreading to arms, legs, head, etc.
- The largest artery is the aorta, which comes from the left side of the heart.
- Label these outgoing vessels as "Arteries".

✔ Summary of Labels:

| Structure | Location | Function |
|------------------|-------------------------------------------|-----------------------------------------|
| Heart | Center of chest | Pumps blood throughout the body |
| Vena Cava | Enters top (superior) and bottom (inferior) of heart | Returns deoxygenated blood to heart |
| Veins | From limbs/organs → heart | Carry blood to the heart |
| Arteries | From heart → limbs/organs | Carry blood away from the heart |

📝 How to Fill in the Worksheet:

- Use arrows or lines pointing to each structure.
- Write the correct term next to each:
- Draw a line to the heart → write "Heart"
- Draw a line to the large vessel entering the top of the heart → write "Vena Cava"
- Draw lines to vessels going from arms/legs to heart → write "Veins"
- Draw lines to vessels going from heart to arms/legs → write "Arteries"

💡 Tip: Remember the rule:
> "Arteries = Away from the heart; Veins = Toward the heart."

If your diagram includes specific labels like "Aorta" or "Pulmonary Artery", those are types of arteries — but since your list only includes general terms, stick to arteries, veins, vena cava, and heart.
