They return less salt to the blood by reabsorption.
When the kidneys detect an increase in salt in the body, they retain water to dilute the salt until it can be eliminated. This can result in a rise in blood pressure.
It is important to control you salt intake because, it can lead to high blood pressure.
In the kidneys there is a structure called the nephron which helps to get rid of salt through water intake using hormones, and it gets excreted by peeing through the urinary tract. You can also sweat it out if the temperature is hot enough.
Nerves detect changes to salt levels in the blood.
