Human Body - Respiratory System (2nd Ed)

Creator: Coronet

Format: 16mm

Sound: sound

Description: To stay alive, the body must take in oxygen and give up carbon dioxide; this exchange is the work of the respiratory system. Here you visually journey with oxygen laden air through the nose and mouth, down the trachea to to the bronchi and lungs where the exchange (diffusion) occurs between the alveoli and capillaries, and carbon dioxide then makes the return trip.
