Breathing in and out: Explore the Respiratory System

Learning Objective

Understand the structures and functions of the respiratory system.

What do you already know about breathing and the respiratory system?

Introduction to the Respiratory System

The respiratory system is responsible for breathing and exchanging oxygen and carbon dioxide.

Organs of the Respiratory System

The main organs include the nose, trachea, lungs, and diaphragm.

Nose and Trachea

The nose filters and warms the air, while the trachea carries air to the lungs.

Lungs and Diaphragm

The lungs are where oxygen and carbon dioxide exchange occurs, and the diaphragm helps in the breathing process.

Gas Exchange

Oxygen is taken in by the blood, and carbon dioxide is removed from the blood in the lungs.

Breathing Process

During inhalation, the diaphragm contracts, and during exhalation, it relaxes, pushing air out.

Common Respiratory Problems

Asthma, bronchitis, and pneumonia are common respiratory issues that affect breathing.

Summary and Review

Recap the key structures and functions of the respiratory system.

Interactive Quiz

Write down 3 things you learned in this lesson.

Have students enter three things they learned in this lesson. With this they can indicate their own learning efficiency of this lesson.

Write down 2 things you want to know more about.

Here, students enter two things they would like to know more about. This not only increases involvement, but also gives them more ownership.

Ask 1 question about something you haven't quite understood yet.

The students indicate here (in question form) with which part of the material they still have difficulty. For the teacher, this not only provides insight into the extent to which the students understand/master the material, but also a good starting point for the next lesson.
