Collateral Circulation

Collateral circulation (pronunciation: kuh-lat-er-uhl sur-kyuh-ley-shuhn) refers to the alternate or secondary vascular routes that blood can take when the primary path is obstructed or compromised. This phenomenon is a crucial aspect of the body's adaptive response to ischemia or inadequate blood supply.

Etymology

The term 'collateral circulation' is derived from the Latin words 'collateralis', meaning 'side by side', and 'circulatio', meaning 'going around'. It essentially refers to the 'side by side' or 'alternate' routes that blood can take to 'go around' an obstruction.
