Science: Label the organs of the human body | Worksheet ... - Free Printable

Let's solve this step-by-step.

The image is a worksheet from PrimaryLeap titled "Major organs of the human body", where students are asked to label the main organs shown in a diagram of the human body. The diagram shows a simplified side view of the human torso with several major internal organs, and lines point from each organ to blank boxes for labeling.

Here’s how we can identify and label each organ:

---

Step 1: Identify the organs based on their position and appearance

Looking at the diagram:

1. Top of the head (brain)
- Located inside the skull.
- This is clearly the brain.

2. Below the brain, near the throat
- A pinkish structure just below the brain, connected to the trachea.
- This is the throat, but more specifically, it's the larynx or voice box, but in basic diagrams, this area often represents the pharynx or throat. However, since it's connected to the lungs and heart, it might be referring to the trachea (windpipe). But given its position, it could also be the throat or larynx.

Wait — looking more closely: the next organ below that is the heart, and above it is the throat. Actually, the structure right below the brain and above the lungs is the throat (pharynx/larynx). But let's go in order.

3. Large red organ in the chest, slightly left
- This is the heart.

4. Two large, pink, spongy organs on either side of the heart
- These are the lungs.

5. Organ beneath the lungs, under the ribs
- This is the liver (on the right side) and possibly the stomach (on the left), but in many diagrams, the liver is shown as a large reddish-brown organ on the upper right side.

6. Green organ under the liver
- This is the gallbladder? Or sometimes labeled as liver itself.

Wait — actually, the green organ is likely the gallbladder, but in many simplified diagrams, the liver is shown as a large organ, and the gallbladder is small and green. But here, the green one is small and sits below the liver.

7. Coiled tube-like structure in the lower abdomen
- This is the intestines, specifically the small intestine and large intestine.

8. Red organ below the intestines
- This is the rectum or anus, but usually the bladder is shown here.

Wait — let’s re-analyze carefully.

Let’s list the organs in order from top to bottom:

Step 2: Match each label box to the correct organ

There are 10 blank boxes, but only 9 lines pointing to organs. Wait — no, actually, there are 10 boxes and 10 lines.

Let’s count the lines:

- One line points to the brain
- One to the throat (pharynx/larynx)
- One to the lungs (probably both together)
- One to the heart
- One to the liver
- One to the stomach
- One to the pancreas?
- One to the kidneys
- One to the intestines
- One to the bladder

Wait — let’s look again.

Actually, the diagram shows:

1. Brain – top of head
2. Throat / Larynx – below brain, pink structure
3. Lungs – two large pink organs on either side of the heart
4. Heart – red organ in center of chest
5. Liver – large organ on the right side, under the lungs
6. Stomach – curved organ below the heart and liver, on the left
7. Pancreas – small organ behind the stomach
8. Kidneys – two bean-shaped organs on either side of the spine, above the intestines
9. Intestines – coiled tubes in the abdomen
10. Bladder – pear-shaped organ below the intestines

But in this diagram, the pancreas is not clearly visible. Instead, we see:

- A green gallbladder under the liver
- Kidneys (two dark red/bean-shaped organs on sides)
- Intestines (coiled yellow/orange)
- Bladder (red, pear-shaped, below intestines)

Also, the liver is shown on the right, and stomach on the left.

Now, let’s assign each label based on the lines:

---

Final Labeling (from top to bottom):

1. Brain – top of head
2. Throat (or Larynx/Pharynx) – below brain, pink structure
3. Lungs – two large pink organs in chest
4. Heart – red organ in center
5. Liver – large organ on right side
6. Stomach – curved organ on left, below heart
7. Gallbladder – small green organ under liver
8. Kidneys – two bean-shaped organs on sides of spine
9. Intestines – coiled tubes in abdomen
10. Bladder – pear-shaped organ below intestines

But wait — the diagram shows only 10 lines, and they connect to:

- Brain
- Throat
- Lungs
- Heart
- Liver
- Stomach
- Gallbladder
- Kidneys (both)
- Intestines
- Bladder

Yes — that makes sense.

Correct Labels:

Let’s now write the labels in the correct order as per the lines:

From top to bottom, left to right:

1. Brain
2. Throat (or Larynx)
3. Lungs
4. Heart
5. Liver
6. Stomach
7. Gallbladder
8. Kidneys
9. Intestines
10. Bladder

But wait — the gallbladder is very small and may not be emphasized in basic science for Year 5. Often, the pancreas is shown instead. Let's double-check.

Looking at the diagram:

- The gallbladder is shown as a small green sac under the liver.
- The pancreas is typically behind the stomach, but not always shown.

In this case, the green organ is likely the gallbladder, which stores bile from the liver.

But in many school diagrams, the pancreas is included. However, here, it's not clearly visible.

Alternatively, perhaps the liver is labeled, and the gallbladder is separate.

Given that, and standard curriculum content for Year 5 Science, the expected labels are likely:

Standard Major Organs (Year 5 Level):

1. Brain
2. Lungs
3. Heart
4. Liver
5. Stomach
6. Intestines
7. Kidneys
8. Bladder
9. Pancreas?
10. Gallbladder?

But the diagram shows:

- Brain ✔
- Throat (pharynx/larynx) ✔
- Lungs ✔
- Heart ✔
- Liver ✔
- Stomach ✔
- Gallbladder ✔
- Kidneys ✔
- Intestines ✔
- Bladder ✔

So all 10 are present.

Final Answer:

Label the boxes in the following order (based on the lines):

1. Brain
2. Throat (or Larynx)
3. Lungs
4. Heart
5. Liver
6. Stomach
7. Gallbladder
8. Kidneys
9. Intestines
10. Bladder

> Note: In some versions, "Throat" might be replaced with "Trachea" or "Larynx", but for Year 5, "Throat" is acceptable.

Summary:

✔ Correct labels (in order):

1. Brain
2. Throat
3. Lungs
4. Heart
5. Liver
6. Stomach
7. Gallbladder
8. Kidneys
9. Intestines
10. Bladder

These are the major organs of the human body shown in the diagram.

Explanation:

This worksheet helps students learn the location and names of key internal organs. It reinforces knowledge of the circulatory system (heart), respiratory system (lungs), digestive system (mouth, esophagus, stomach, intestines, liver, gallbladder), excretory system (kidneys, bladder), and nervous system (brain).

By labeling these organs, students develop anatomical awareness and understand how different systems work together.
