The precise regulation of blood pressure and the distribution of blood flow are essential to ensure that vital organs and tissues receive an adequate supply of oxygen and other nutrients. Blood pressure and tissue blood flow are controlled by carefully regulating resistance in arteries. Neural activity in the sympathetic nervous system leads to the release of chemicals (neurotransmitters) that constrict peripheral blood vessels and increase arterial resistance. Therefore, the sympathetic nervous system is an important regulator of blood pressure, tissue blood flow and vascular function.

血压的精确调节和血流的分布对于确保重要器官和组织获得充足的氧气和其他营养物质至关重要。血压和组织血流量是通过仔细调节动脉阻力来控制的。交感神经系统中的神经活动导致化学物质（神经递质）的释放，这些化学物质收缩外周血管并增加动脉阻力。因此，交感神经系统是血压、组织血流量和血管功能的重要调节器。
