Form 3 Questions

In the school today, we did not have any experiment or project.

We had started a new topic.. the human respiratory system. So the teacher gave some questions to do:

1. Name the structures of the respiratory system:
- nasal cavity
- trachea
- ribs
- intercastal muscles
- bronchus
- bronchioles
- lungs
- diaphragm

2. How is the respiratory system protected?
It is protected by the ribs cage

3. What will happen if a rib breaks and punctures the lung?
Without immediate medical attention, he will die/

In Malaysia form 3 is for the age of 15 years. there is a national examination at the end of the year. The exam is called PMR.
