What it does is it increases the amount of sodium and chloride ions that are reabsorbed back into our blood and increases the amount of hydrogen and potassium ions that are secreted back into our urine. So the net result is a higher flow, a higher movement of ions into our blood plasma. And that basically drags more water into our blood plasma. So that increases the blood volume inside our blood, and that basically increases the blood pressure inside our blood vessels. Now, the next set of hormones that are secreted by the adrenaline cortex is Cortisol and Cortisone. So Cortisol and Cortisone are very similar in their structure as well as in their functionality.
