Sympathetic nervous system is one of the parts of Autonomic nervous system and the other part is Parasympathetic nervous system.
As a whole the autonomic nervous system controls the unconscious responses of our body.
The main function of the Sympathetic nervous system is to stimulate the 3F response of the body. Here 3F refers to Fight, Flight and Freeze. Adrenal gland is stimulated by this system which secretes adrenaline. Due to the effect of adrenaline heart neat increases, blood pressure increases, pupils dilate, sweat glands are activated, peristalsis in the gut is inhibited, and kidney secretion increases.
Most of this secretory organ comprises of acinar or exocrine cells that discharge the pancreatic juice containing stomach related compounds, for example, amylase, pancreatic lipase, and trypsinogen, into the pipes, that is, the fundamental pancreatic and the extrapancreatic channel
The endocrine cells are bunched together, along these lines shaping the supposed islets of Langerhans, which are little, island-like structures inside the exocrine pancreatic tissue that represents just 1–2% of the whole organ
drop in glucose triggers the arrival of glucagon by the pancreas. in the liver, glucagon enacts glycogen phosphorylase by animating its cAMP-subordinate phosphorylation and invigorates gluconeogenesis by bringing down [fructose 2,6 bisphosphate] consequently animating FB Pase-1
