blood to flow more forcefully‚ this effect makes most of the arterioles to constrict and some arterioles dilate‚ which leads to an increase blood supply where needed. In order to increase blood it is vital for the sympathetic division to get the kidneys to decrease their secretion of salt and water; this will mean an increase in blood volume and blood pressure then returns to normal. Blood pressure can be lowered by the actions of artrial natriutretic peptide (ANP) hormone. Atrial natrriuretic hormones
