The vascular system consists of arteries, veins and other blood vessels that deliver oxygen and nutrient-rich blood to every cell in your body. The arteries and veins can become damaged over time, hindering blood flow and increasing the risk of chronic disease.
Dr Oz: What Happens When You Die? Have you ever wondered what it really feels like when you die? Dr Oz claimed that, with the help of new research, we have a better look than ever before at what happens during the seven minutes of life. During the final minutes before death, the person will look as if theyâre sleeping. The heart slows, their pulse weakens, and their blood pressure drops.
You are really asking three questions; Your brain begins to die after 4-6 minutes without oxygenated blood being delivered to it. If your blood is flowing out from a wound that causes a few things to happen...less blood is delivered to organs, therefore less oxygen and eventually you will bleed out and that's it.
