Arterial anastomosis
An arterial anastomosis is when more than one artery fuses before giving rise to arterioles. An arterial anastomosis in effect provides an insurance policy for capillary beds: If one artery is compressed or blocked, the others can continue to deliver blood to the capillary bed, and dependent tissues will not be damaged. Arterial anastomoses occur in the brain, in the coronary circulation, and in many other sites as well.

This ensures that the intimal edges will be everted
it is important especially in joints where joint movements can impede major arterial channels to supply blood to the joint, therefore anastomosis helps to insure blood flow. Besides this, anastomosis is important when a major artery has been blocked and the blood then can be carried through anastomotic arteries.
