Document Summary

Occupies all of thoracic cavity except mediastinum. All structures beyond primary bronchi are within the lungs. Cardiac impression only on left lobe: only 1 fissure. Branch to form pulmonary capillary network (surrounding alveoli) Venous return of blood via pulmonary veins o. Bronchial artery ends before reaching alveoli: after gas exchange blood enters pulmonary veins - deoxygenated blood mixes with o2 blood but only a small amount so no big effect. Non-small cell lung cancer: accounts for about 85% of lung cancers, adenocarcinoma. Most common form of lung cancer among both men and women o o. Forms within the epithelial lining of the bronchioles. Refer to non-small cell lung-cancers that are neither adenocarcinomas or squamous cell carcinomas. Small cell lung cancer: accounts for remaining 15% of lung cancers, grows more rapidly and spreads to other parts of the body earlier. Svc obstruction o: medial surface of right or left lung.
