Patient was educated on the various parts of respiratory zone of the respiratory tract along with their functions as follows:
- Respiratory bronchioles
- Terminal bronchioles further divide into smaller and thin walled respiratory bronchioles.
- Air from the terminal bronchioles of the conduction zone enters the respiratory bronchioles and is conducted into the next part of the respiratory zone, the alveoli.
- Exchange of gases begins in the respiratory bronchioles, though the main site of gas exchange is the alveoli.
- Alveolar ducts and alveoli
- Air from the respiratory bronchioles enter the alveolar ducts and alveoli, the terminal part of the respiratory tract.
- Alveoli are thin walled sacs and are richly supplied with blood by the pulmonary capillaries.
- The thin walled structure of the pulmonary capillaries and the alveoli allow for diffusion of gases across the membranes.
- Carbon dioxide from the pulmonary capillaries will diffuse into the alveoli and oxygen from the air in the alveoli will diffuse into the blood in the pulmonary capillaries, to be carried by the hemoglobin, through the pulmonary veins to the left heart.
- This oxygen rich blood will get distributed to all the vital organs of the body from the left heart.
