What is collateral circulation?


Collateral circulation is a network of tiny blood vessels, and, under normal conditions, not open. When the coronary arteries narrow to the point that blood flow to the heart muscle is limited (coronary artery disease), collateral vessels may enlarge and become active. This allows blood to flow around the blocked artery to another artery nearby or to the same artery past the blockage, protecting the heart tissue from injury.

  1. How can a woman be expected to be happy with a man who insists on treating her as if she were a perfectly normal human being. See the link below for more info.
