Document Summary

Trachea: tube of connective tissue and smooth muscle, descends from larynx into mediastinum, 12cm long and 2. 5cm diameter, rings of cartilage (c-shaped incomplete on posterior surface, esophagus lies posteriorly, connected inferiorly to bronchi. If caught early enough the tumour can be removed. Alveoli type ii cells: cuboidal cells, secretes surfactant to decrease surface tension and help the lungs expand, without surfactant your lungs would collapse, complex of lipids and proteins. Hilus (there is also a hilus in the kidneys: slit in medial surface of lung for, pulmonary arteries, pulmonary veins, bronchi, lymph vessels, nerves. Anatomy of the right lung: upper, middle, and lower lobe, the upper and middle lobe is separated by a horizontal fissure, the middle and lower lobe is separated by an oblique fissure. Pulmonary vessels: the left ventricle pumps blood to the body, the right ventricle pumps blood to the lungs through the pulmonary arteries, pulmonary veins bring back highly oxygenated blood to the left atria.
