Goblet cells produce mucus to trap dirt particles and bacteria from the air. 4 of 11 Brochioles are made of muscle lining with epithelial cells, what does this help with? Muscle allows them to constrict so that they can control the flow of air in and out of the alveoli 5 of 11 What are alveoli? minute air sacs at the end of the bronchioles 6 of 11 What do alveoli contain? elastic fibres and collagen and are lined with epithelium 7 of 11 What is the alveotar membrane The gas exchange surface 8 of 11 What is the diaphragm? a broad band of muscle underneath the lungs forming the base of the thoracic cavity 9 of 11 What are pleural membranes? they encase the lungs and secrete pleural fluid to reduce the friction from the movement of the lungs during breathing 10 of 11 What is pulmonary ventilation? a measure of how much air is taken in and out of the lungs in a given time.
