digestive system and respiratory system worksheet - worksheetszone - Free Printable

I'll solve this problem by identifying which organs belong to the digestive system and which belong to the respiratory system.

First, let me look at the image closely to understand what's being asked.

The image shows a worksheet titled "Digestive system VS Respiratory system" with a cartoon girl showing internal organs. There are two columns: "Digestive system" on the left (in blue) and "Respiratory system" on the right (in red). Below the figure, there's a list of organs that need to be sorted into the correct system:
- Stomach
- Lungs
- Long intestine
- Trachea
- Alveoli
- Small intestine
- Nasal cavity
- Mouth
- Bronchi

Let me now categorize each organ based on my knowledge of human anatomy:

Digestive System Organs:
- Stomach - breaks down food
- Long intestine (colon) - absorbs water and forms feces
- Small intestine - absorbs nutrients from food
- Mouth - begins digestion through chewing and saliva
- (Note: "Long intestine" is likely meant to be "Large intestine")

Respiratory System Organs:
- Lungs - exchange oxygen and carbon dioxide
- Trachea - windpipe that carries air to lungs
- Alveoli - tiny air sacs in lungs where gas exchange occurs
- Nasal cavity - filters, warms, and humidifies air
- Bronchi - airways in the lungs that branch from the trachea

Now I'll organize the answer according to the worksheet format.

Digestive System:
1. Stomach
2. Long intestine (Large intestine)
3. Small intestine
4. Mouth

Respiratory System:
1. Lungs
2. Trachea
3. Alveoli
4. Nasal cavity
5. Bronchi

This completes the task of writing each organ in the correct system where it belongs.
