Document Summary
2. parts of the lung lungs separated into lobes. 3. tissue, but lungs are mostly air space epiglottis: flap that sticks up, closes off throat. 4. strings that stretch tight, tighter you stretch, higher the pitch) 6. airways held open in the upper layers. Goblet cells: create & dump mucus injected different colors. Lung is divided even further divided into more segments. 7. settle in upper portion of lungs because of a lot of oxygen. Use to just remove entire pieces of lung surgically to cure it. 8. cilia: how you keep the airways clear: blood vessels, pulmonary arteries (deoxygenated blood), pulmonary veins(oxygenated blood, keep going thru the divisions. Around 12 generations, have cartilage holding things open. Each airway gets smaller, total cross-sectional area gets bigger. Most of the resistance is in the first few generations. Local control over blood flow in systemic circuit. Alveoli, around 23 generation: alveoli: cluster of grapes. Take each grape cover it with capillaries network.
