Pick one chemical that influences BP and describes how that
Solution
A porrion of medulla oblongata having cluster of sympethetic nerve fiber is vascomotor that regulate blood pressure and other homeostatic process. Sympethetic nerve fiber travel around the tunica media of the artery , secrete nurotrasnsmitter such as norepinephrine into the extracellular fluid surrounding the smooth muscle tunica media . The smooth muscle membrane have alpha and beta adrenergic receptors for neurotrasnsmitter . Activation of alpha adrenergic receptor promotes vasoconstriction while activation of beta adrenergic resulting in vasidilatio .
Endothelin and angiotensin are vasocontrictors while nitrigen oxide and prostacyclin are vasodialtor.
Aldosterone is produced in the cortex of the adrenal gland , 7n a healthy individual the renin angiotensin aldosterone system helping to regulate and controle blood pressure . Hyperaldosteronism cause high blood pressure while hypoaldosteronism causeAddison\'s disease .
