Document Summary
Water at surface, surface tension pulling water together. When you breathe in, alveoli expand, but then we want it to collapse again surfactants exist to cut bonds between molecules of water. During inspiration, volume increases, and expiration, volume decreases. Pleura is like a suction cup where molecules aare pushing against the suction. Intrapleural space cup to make it (cid:498)stick(cid:499) liquid is non-expansible, so )t can"t expand like air. Pneumothorax and ventilation two sides of lungs have separated as shown in diagrams 2 and 3. Expiration means air coming out of the wound. Piece of pleura may be too developed, allowing air in and must be removed (cid:523)good thing you weren"t here, he showed a video of the whole surgery lol. Usually fluid is blood, pushing against the lungs so it can"t expand tachypnea must breathe faster. Must identify source of bleeding and drain blood fluid going into the cavity similar to organ going inside the cavity.
