Circulatory System Anatomy Activity Sheet PDF - Free Printable

This image is a Circulatory System Activity Sheet from *AnatomyStuff*, designed to help students label major blood vessels in the human body. The diagram shows the anterior (front) view of the circulatory system, with blank labels pointing to various arteries and veins.

Let’s identify and label each blank based on standard human anatomy:

🔹 Labeling Guide (from top to bottom):

1. Top right (head/face)
→ External Carotid Artery
*(Supplies blood to the face and scalp)*

2. Top left (neck)
→ Internal Jugular Vein
*(Drains blood from the brain and head back to the heart)*

3. Middle right (upper chest)
→ Subclavian Artery
*(Carries blood from the aorta to the arms)*

4. Middle left (upper chest)
→ Brachiocephalic Trunk (or Brachiocephalic Artery)
*(First branch of the aortic arch; splits into right subclavian and right common carotid arteries)*

5. Center (chest, descending)
→ Aorta
*(Main artery that carries oxygenated blood from the heart to the body)*

6. Lower middle (abdomen)
→ Inferior Vena Cava
*(Largest vein; returns deoxygenated blood from the lower body to the heart)*

7. Left side (upper arm)
→ Axillary Artery
*(Continuation of subclavian artery; supplies blood to upper arm)*

8. Right side (upper arm)
→ Brachial Artery
*(Major artery in the upper arm; branches into radial and ulnar arteries)*

9. Left side (lower leg)
→ Femoral Artery
*(Main artery supplying the thigh and leg)*

10. Right side (lower leg)
→ Popliteal Artery
*(Continuation of femoral artery behind the knee)*

11. Bottom left (foot)
→ Dorsalis Pedis Artery
*(Artery on the top of the foot; continuation of the anterior tibial artery)*

12. Bottom right (leg)
→ Tibial Artery
*(Usually refers to posterior tibial artery; runs down the back of the leg to the foot)*

✔ Final Answer: Labels for Each Blank (from top to bottom, left to right):

| Label Position | Correct Name |
|----------------|--------------|
| 1. Top right (face) | External Carotid Artery |
| 2. Top left (neck) | Internal Jugular Vein |
| 3. Middle right (upper chest) | Subclavian Artery |
| 4. Middle left (upper chest) | Brachiocephalic Trunk |
| 5. Center (descending vessel) | Aorta |
| 6. Lower middle (abdomen) | Inferior Vena Cava |
| 7. Left (upper arm) | Axillary Artery |
| 8. Right (upper arm) | Brachial Artery |
| 9. Left (thigh) | Femoral Artery |
| 10. Right (behind knee) | Popliteal Artery |
| 11. Bottom left (foot) | Dorsalis Pedis Artery |
| 12. Bottom right (lower leg) | Posterior Tibial Artery |

📌 Notes:

- This activity sheet helps reinforce understanding of major systemic arteries and veins.
- The aorta is the largest artery, branching into several key vessels.
- The inferior vena cava collects blood from the lower body.
- The jugular veins return blood from the head and neck.

✔ Tip: To remember this, follow the path of blood flow:
- Heart → Aorta → Arteries → Capillaries → Veins → Vena Cava → Heart
