| 11. | It is closed by the diaphragm, which separates the thoracic cavity from the abdominal cavity.
|
| 12. | When breathing, downward motion of the thoracic diaphragm creates negative pressure in the thoracic cavity.
|
| 13. | Strings go p-ling in my thoracic cavity.
|
| 14. | The thoracic cavity expands and air rushes into the lungs due to the negative pressure, producing inspiration.
|
| 15. | The thoracic outlet is the lower opening of the thoracic cavity whose edges are the lowest ribs.
|
| 16. | For example, because of the smaller distance in the thoracic cavity between the sternum and anteroposterior axis.
|
| 17. | During inspiration, the negative pressure in the thoracic cavity will cause increased pressure into the right ventricle.
|
| 18. | It has been hypothesized that both reach the brain from the thoracic cavity via major blood vessels.
|
| 19. | When the diaphragm contracts, the thoracic cavity is expanded, reducing intra-thoracic pressure and drawing air into the lungs.
|
| 20. | The larynx is one half the length of the vertebral column and fills out most of the thoracic cavity.
