Blood vessels, like roads, connect all parts of our body to the heart. Through those well enclosed walls, blood circulates to every crevice to deliver oxygen and nutrients vital for survival of tissues. The heart pumps blood into the aorta that branches out into arteries that in turn further branch into capillaries, together fulfilling the task of keeping the tissues and organs well nourished. But what would happen if these blood vessels got damaged or blocked? The oxygen and nutrient supply would get hindered and tissues may start dying of starvation. This inadequate blood supply- Ischemia- can lead to necrosis, gangrene, and regional paralysis.
