|
|
Term
| What travels with the segmental bronchi through the middle of the broncho-pulmonary segment? |
|
Definition
| Segmental bronchi and artery. |
|
|
Term
| What is the result of sympathetic innervation to the lung? |
|
Definition
| Vasodilation of pulmonary and bronchial vessels, decreased mucus secretion & bronchodilation. The book differs from my answer in that it states that the sympathetics vasoconstricts the pulmonary and bronchial arteries. Supposedly this increases the pressure, but does not make sense to me so this particular point (vasodilation/vasoconstriction) will not be tested over. |

Term
During inspiration describe the changes in shape and volume of the thoracic cavity.
|
|
Definition
| All volumes increase, thus pressure decrease within the thoracic cavity. The ribcage elevates increasing the side-to-side diameter (bucket handle) and the anterior-posterior diameter (pump handle), while the diaphragm contracts and drops, increasing the superior-inferior diameter. |
