A) structural features of alveoli make them an ideal place for gas exhange
- Thickness odf alveoli is one celled that makes the exchange surface very thin and shorten the distance for gases to move.
- alveoli is surrounded by blood capillaries that provide a good blood supply.
B). Mucus traps smaller particles like pollen and smoke. it protect the lung through mucociliary clearance against foreign particles and chemicals entering the lung.
C)cillia are the hair like structures persent in trachea act as defence system as it sweep fluids and foreign particles out of the airway so that they stay out of the lungs.
