Let's solve the labeling task on the image of
"The Circulatory System".
Step 1: Understand the diagram and labels
We are given a human body diagram showing the circulatory system, with four blue arrows pointing to different parts. Below the diagram, there are four words to choose from:
- blood vessels
- heart
- blood
- nutrients and oxygen
Our goal is to match each arrow to the correct label.

Step 2: Analyze each arrow
1.
Top-left arrow (pointing to the magnified circle with red blood cells):
- This shows a close-up of
blood, including red blood cells.
- So, this should be labeled:
blood
2.
Arrow pointing to the heart (center of the chest):
- The organ in the center of the chest is the
heart.
- So, this should be labeled:
heart
3.
Arrow pointing to the network of red and blue tubes throughout the body:
- These are the
blood vessels (arteries, veins, capillaries).
- So, this should be labeled:
blood vessels
4.
Arrow pointing to the substance being carried in the blood (in the magnified view):
- The text says the circulatory system carries
nutrients and oxygen.
- In the magnified circle, we see red blood cells (which carry oxygen) and other components (nutrients).
- So, this should be labeled:
nutrients and oxygen
---
Step 3: Final Matching
Let’s assign the labels to the boxes:
-
Top-left box (magnified blood): →
blood
-
Left-middle box (pointing to the blood vessel network): →
blood vessels
-
Right-top box (pointing to the heart): →
heart
-
Right-bottom box (pointing to the flow in vessels): →
nutrients and oxygen
> Note: The arrow from the right-bottom points to the blood vessels carrying substances — so it refers to what is being transported:
nutrients and oxygen.

✔ Correct Answers:
| Box Position | Label |
|--------------|-------|
| Top-left | blood |
| Left-middle | blood vessels |
| Right-top | heart |
| Right-bottom | nutrients and oxygen |
---
Explanation Summary:
- The
heart pumps blood.
-
Blood vessels transport blood throughout the body.
-
Blood contains red blood cells and plasma that carry substances.
-
Nutrients and oxygen are carried by the blood to all body parts.
This matches the description: *"The circulatory system carries nutrients from food and oxygen from air around the body."*
