In the first empty box I would state that the neurotransmitters cause the smooth muscles in the vessel to relax and expand.
In the last empty box I would state that the Blood pressure rises.
Explanation:
Neurotransmitters can effect the blood vessels in both ways.
When vessels get narrow more pressure is needed: Blood Pressure increases.
When vessels expand less pressure is needed: Blood Pressure Decreases
Your answer is True.
Hope this helps.
