Lungs Two spongy organs in the thoracic cavity enclosed by the diaphragm and rib cage, responsible for respiration Lobes Subdivisions of the lung (visceral pleura) and lining the thoracic cavity (parietal pleura) Pleural cavity Potential space between visceral and parietal layers of the pleura Diaphragm Muscular partition that separates the thoracic cavity from the abdominal cavity and moves up and down to aid respiration Mediastinum Partition that separates the thorax into two compartments and encloses the heart, esophagus, trachea, and thymus gland Mucous membranes Thin sheets of tissues that line respiratory passages and secrete mucus, a viscid fluid Cilia Hairlike processes from the surface of epithelial cells, such
