Epitheloid cells are [[epithelium]]-like cells that can secrete enzymes. They are thought to produce the hormone [[renin]], a [[protease]], which splits [[angiotensinogen]] into [[angiotensin I]]. Angiotensin I can then be split into [[Angiotensin II|Angiotensin II ]]<nowiki /> which is a highly effective [[vasoconstrictor, vasoconstrictor|vasoconstrictor]] and can therefore increase blood pressure.
