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.
When you die your heart stops pumping blood around your body, thus depriving your cells of oxygen, which rapidly begin to die. Decomposing starts almost immediately, with the skin going through several changes in colour as the blood stops circulating leaving the body an ashen color. However different cells die at different rates. For example, brain cells die within a few minutes, whilst skin cells can survive over 24 hours after death. Soon after death rigor mortis occurs, which is caused by a complex chemical reaction (involving lactic acid and myosin), which forms a gel like substance which creates the body's stiffness.
