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)

Classify the following characteristics to demonstrate your knowledge of differences between the sympathetic and parasympathetic
divisions of the autonomic nervous system.
Sympathetic Nervous System
Most ganglia lie close to the
spinal cord and form two chains
of ganglia-one on each side of
the spinal cord
Increases intestinal motility
and stimulates intestinal
secretion
Postganglionic axons are
generally short
Preganglionic axons are
generally short
Postganglionic axons release
NE that binds to adrenergic
receptors located on the
effectors
Decreases heart rate,
contractility, and conduction
velocity
Ganglia lie within, or very
close to, innervated organs
Decreases intestinal motility
and inhibits intestinal
secretion
Long preganglionic axons
release ACh that binds to
nicotinic receptors located within
the ganglia
Neurons leave the CNS from
the thoracic and lumbar
regions of the spinal cord
Parasympathetic Nervous System
Generalized activation is
called the fight-or-flight
response…
