Excretory system has organs {kidney}| in middle-trunk back wall. Kidney regulates blood pH, blood salt, blood volume, and total body water. Increasing blood water increases blood pressure. Increasing blood pressure increases water filtration into kidney, reducing water in blood and reducing blood pressure. Kidney problems can cause edema. Kidney makes aldosterone, which controls blood pressure.
