HEART OF A DOG

The Irish Mail on Sunday - - MORE -

We hAve two coro­nary ar­ter­ies but only one feeds oxy­genated blood into the heart. If it gets blocked then that part of the heart dies and we have a heart at­tack. A dog’s heart has many coro­nary ar­ter­ies, so if one be­comes blocked the oth­ers can still feed blood to that part of the mus­cle.
