Hello Friend♥
This is the answer to ur question!!
Platelets are tiny blood cells that helps our body from clots to stop bleeding If one of our blood vessels got damaged it sends out signals that are picked up by platelets.
The chief difference between arteries and veins is between the job they do..
Arteries they carry oxygenated blood away from heart to body..
Veins carry oxygen -poor blood back from body to heart..
Arteries are thick muscle layer..
Veins are comparatively thin...
Hope it Helps!!
