1) The left lung contains 2 of these, where as the right lung contains 3. Each one is served by its own artery and vein and receives air from an individual bronchus. a) Pleural Cavity b) Lobes c) Pleural membrane d) Lung e) Thoracic cavity f) Pleural fluid 2) Each of the lungs is enclosed in a double membrane known as the ...................................These membranes keep the lungs seperate and air tight. These membranes secrete a fluid which allows for lubrication of the lungs. a) Thoracic cavity b) Alveoli c) Visceral Pleura d) Pleural membrane e) Pleural Cavity f) Pleural fluid 3) This is the chest space and consists of the lungs and heart. Is it protected by the ribs and the scapula at the back of the rib cage. a) Visceral Pleura b) Alveoli c) Lobes d) Pleural fluid e) Pleural Cavity f) Thoracic Cavity 4) A thin membrane tissue layer that sticks to the lung surface. This is the innermost of the two pleural membranes and dips into the spaces between the lobes. a) Visceral Pleura b) Lobes c) Alveoli d) Pleural Cavity e) Thoracic Cavity f) Pleural fluid 5) The two pleural membranes produce this fluid which fills the cavity between them. This acts as lubrication and prevents friction during respiration. a) Alveoli b) Thoracic Cavity c) Visceral Pleura d) Pleural Fluid e) Pleural Cavity f) Lung 6) These are small sacs in the lungs allowing gas exchange. The process of O2 and CO2 moves between the lungs and the blood. This leads onto the capillaries. a) Visceral Pleura b) Thoracic Cavity c) Bronchus d) Pleural Cavity e) Lung lobes f) Alveoli 7) This is a domed shaped ring of muscle responsible for moving the rib cage during inhalation and exhalation. It contracts during inspiration, increasing the size of the chest cavity, and relaxes during expiration decreasing the size of the chest cavity. a) Lung lobes b) Diaphragm c) Intercostal Muscles d) Alveoli e) Visceral Pleura f) Bronchus 8) These are located in between the ribs. The muscles contract to help with inhalation and exhalation. They are located on the inner and outer surfance of the ribcage. a) Diaphragm b) Lung lobes c) Visceral Pleura d) Bronchus e) Internal and External intercostal muscles f) Alveoli
