When your body mounts a sympathetic response, it causes the smooth muscle in your bronchioles to relax and dilate (get wider). By contrast, a parasympathetic response causes the smooth muscles in your bronchioles to contract and constrict (get narrower). This seems strange because fight-or-flight responses seem like they should upregulate activity and cause more contractions. A benefit of bronchiole dilation during fight or flight responses is that it

Question
Hello, May I get help on this question very soon please? I do not understand it. Question: When your body mounts a sympathetic response, it causes the smooth muscle in your bronchioles to relax and dilate (get wider). By contrast, a parasympathetic response causes the smooth muscles in your bronchioles to contract and constrict (get narrower). This seems strange because fight-or-flight responses seem like they should upregulate activity and cause more contractions. A benefit of bronchiole dilation during fight or flight responses is that it...(see image)
**Oxygen Transport and Exchange** **YES** - **Facilitates Oxygen Transfer**: It makes it easier to move O₂ from hemoglobin into tissues. - **Blood Oxygen Transfer Difficulty**: It makes it harder to squeeze O₂ into the blood. - **Alveolar Oxygen Flow**: Allows more O₂ to flow down into your alveoli. In this diagram, there are no graphs or visual data, just informational points summarizing aspects of oxygen transport and exchange in the human body.
