Respiratory System

Respiratory system lesson for kids. The lesson shows animation of ventilation and respiration. It covers the journey of air into the lungs, and the transfer of oxygen from the alveoli sacs to the red blood cells in the capillaries.

Lesson on respiratory system. It describes the respiratory surface, and explains how worms, insects, fish and mammals take in oxygen and release carbon dioxide. The lesson covers the major organs of the human respiratory system - pharynx, trachea, bronchus, bronchiole and alveoli. It also explains how oxygen and carbon dioxide are carried on the hemoglobin.
