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 and components of the human circulatory system. The diagram shows a full-body anterior view with lines pointing to various parts of the circulatory system, each with an empty box for labeling.

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

---

🔹 Top of the Diagram (Head & Neck)

1. Upper right box (pointing to head/face):
→ Carotid Artery
*(Specifically, the common carotid artery supplies blood to the head and neck.)*

2. Middle right box (pointing to neck):
→ Jugular Vein
*(The internal jugular vein drains blood from the brain and face.)*

3. Lower right box (pointing to upper chest):
→ Subclavian Artery
*(Carries blood from the aortic arch to the arms.)*

4. Left side, top (pointing to head):
→ Carotid Artery
*(Same as above—left side.)*

5. Left middle (pointing to shoulder area):
→ Subclavian Vein
*(Drains blood from the arm into the superior vena cava.)*

6. Left lower (pointing to upper torso):
→ Aorta
*(The main artery carrying oxygenated blood from the heart; visible here as it descends through the thorax.)*

---

🔹 Mid-Body (Torso & Abdomen)

7. Right side, mid-torso:
→ Superior Vena Cava
*(Large vein returning deoxygenated blood from the upper body to the heart.)*

8. Left side, mid-torso (pointing to abdominal region):
→ Inferior Vena Cava
*(Returns deoxygenated blood from the lower body to the heart.)*

9. Right side, near pelvis:
→ Common Iliac Artery
*(Branches off the aorta to supply blood to the legs.)*

10. Left side, near pelvis:
→ Common Iliac Vein
*(Drains blood from the legs and joins to form the inferior vena cava.)*

---

🔹 Lower Body (Legs)

11. Right leg, upper thigh:
→ Femoral Artery
*(Main artery supplying blood to the leg.)*

12. Left leg, upper thigh:
→ Femoral Vein
*(Returns blood from the leg to the heart via the iliac veins.)*

13. Right leg, lower calf:
→ Popliteal Artery
*(Continuation of femoral artery behind the knee.)*

14. Left leg, lower calf:
→ Popliteal Vein
*(Drains blood from the lower leg.)*

15. Right foot (distal end):
→ Dorsalis Pedis Artery
*(Artery in the foot that supplies blood to the toes.)*

16. Left foot (distal end):
→ Great Saphenous Vein
*(Largest superficial vein; runs from the foot up to the groin.)*

| 2 (middle right) | Jugular Vein |
| 3 (lower right) | Subclavian Artery |
| 4 (top left) | Carotid Artery |
| 5 (middle left) | Subclavian Vein |
| 6 (lower left) | Aorta |
| 7 (right mid-torso) | Superior Vena Cava |
| 8 (left mid-torso) | Inferior Vena Cava |
| 9 (right pelvis) | Common Iliac Artery |
| 10 (left pelvis) | Common Iliac Vein |
| 11 (right thigh) | Femoral Artery |
| 12 (left thigh) | Femoral Vein |
| 13 (right calf) | Popliteal Artery |
| 14 (left calf) | Popliteal Vein |
| 15 (right foot) | Dorsalis Pedis Artery |
| 16 (left foot) | Great Saphenous Vein |

🧠 Tips for Students:

- Arteries carry blood away from the heart (usually oxygenated, except pulmonary arteries).
- Veins carry blood toward the heart (usually deoxygenated, except pulmonary veins).
- The aorta is the largest artery.
- The vena cavae are large veins returning blood to the heart.
