The arterial and capillary walls are incredibly strong. This is true otherwise you would be bleeding just by tapping yourself.
arterial walls has smooth muscle and elastic fibers (strong and flexible) and capillaries are made up of a single layer of endothelial cells (thin).

only metabolic wastes out of the capillary
The expansion and contraction of the arterial walls is the pulse.
Hydrostatic pressure is high at the arterial end of a blood capillary because this is where blood enters the capillary under high pressure from the heart. This pressure helps to push fluid and nutrients out of the capillary and into the surrounding tissues. This process is essential for delivering oxygen and nutrients to cells and removing waste products.

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.
