• 
  Baroreceptors located in the Aortic Arch and Carotid pathway monitor mean arterial pressure.
  
• Short term regulations are mediated by the autonomic nervous system.
  
• The blood pressure is monitored by the barorecptors, while the regulation is controlled by the vasomotor centre in the medulla, which regulates sympathetic or parasympathetic responses according the a rise or fall in blood pressure
  
• A drop in blood pressure is observed by the baroreceptor and this leads to increase in sympathetic tone and decrease in parasympathetic tone. While a rise in blood pressure leads to an increase in parasympathetic tone and decrease in sympathetic tone.
  
• An increase in sympathetic tone gives rise to a rise in peripheral vascular resistance, venous tone, heart rate and contractility of the myocardium.
  
• Long term regulations are regulated by humoral factors that regulate blood volume by Sodium and water retention.
  
• Renin secretion is directly affected by the changes in renal blood flow and pressure, which in turn directly affects mean arterial pressure.
  
• A drop in renal bloodflow or pressure leads to an increase in renin secretion.
  
• Increase in renin secretion can also be stimulated by an increase in sympathetic outflow.
  
• Increase in renin circulation leads to an increase in angiotensin II produced.
  
• Angiotensin II vasoconstriction effects and can directly raise blood pressure.
  
• Angiotensin II stimulates the secretion of aldosterone which acts on the kidney to retain Sodium and water, which leads to an increase in blood volume.
  
• Beta Adrenegic receptors in the heart respond to norepinephrine and epinephrine which are neurotransmitters released to regulate the sympathetic nervous system.
• Muscarinic cholinergic receptors bind to Acetylcholine a neurotransmitter which is released by the parasympathetic nervous system.

This is my bpharm practical... yawn im so bored.... here jeremy..
