the brain. there really is no one organ that controls blood pressure. blood pressure is controlled through how much blood goes through your heart and a delicate body balance achieved through the cardiovascular central nervous and urinary systems. neurotransmitters in the brain signal the heart to beat quicker and increase blood pressure when it becomes too low. the change in your heart beating then changes the volume and force of blood going through the kidneys and the sodium balance. this action further impacts the fluid in your blood vessels and either lowers or increases your blood pressure.
