What is Breathing System about?
The lesson focuses on the role of muscles in breathing, explaining how inhalation and exhalation occur through the contraction and relaxation of intercostal muscles and the diaphragm. Key components of the breathing system, including the trachea, bronchi, and alveoli, are outlined, emphasizing that muscle action, not lung movement, controls breathing. Activities are included to help students model and understand the mechanics of breathing.
