=== Heart ===
The pumping force of the [[human heart|heart]] should help to keep a normal pressure within the [[blood vessel]]s. But if the heart begins to fail (a condition known as [[congestive heart failure]]) the pressure changes can cause very severe water retention. In this condition water retention is mostly visible in the [[human leg|leg]]s, feet and [[ankle]]s, but water also collects in the [[lungs]], where it causes a chronic [[cough]]. This condition is usually treated with [[diuretics]]; otherwise, the water retention may cause breathing problems and additional stress on the heart.<ref name=":0">{{Cite journal|last1=Casu|first1=Gavino|last2=Merella|first2=Pierluigi|date=July 2015|title=Diuretic Therapy in Heart Failure – Current Approaches|journal=European Cardiology Review|volume=10|issue=1|pages=42–47|doi=10.15420/ecr.2015.10.01.42|issn=1758-3756|pmc=6159465|pmid=30310422}}</ref>
