ANP (atrial natriuretic peptide) is produced by the atria of the heart in response to high blood pressure. Its primary function is to lower blood pressure by increasing the excretion of sodium and water by the kidneys. ADH (antidiuretic hormone) has the opposite effect, decreasing urine output and increasing blood volume and pressure. Aldosterone, produced by the adrenal glands, increases the reabsorption of sodium and water in the kidneys, which can lead to increased blood volume and pressure. Norepinephrine is a neurotransmitter that can increase blood pressure by constricting blood vessels.
