- The decrease of oxygen to at least one body part is known as hypoxia. The total lack of oxygen is known as anoxia. Brain cells are destroyed after 4 to 6 minutes without oxygen. When the flow of oxygen to the brain is completely cut off, a person will lose consciousness within 10 seconds. Extended hypoxia leads to brain damage and ultimately death.

Why Do We Need Oxygen? Humans need oxygen to provide nutrients to all of the cells in their bodies. If tissues and cells go without oxygen, then they begin to die quickly. For example, brain cells can only go without oxygen for three minutes before they begin to die. After three minutes of no oxygen, permanent brain damage begins to spread throughout the brain's tissues. The body also needs energy in order to function properly.

Human heart shuttles 2,000 gallons of blood through 60,000 miles of blood vessels In under a minute, your heart can pump blood to every cell in your body. And over the course of a day, about 100,000 heart beats shuttle 2,000 gallons of oxygen-rich blood many times through about 60,000 miles of branching blood vessels that link together the cells of our organs and body parts. That's a hefty job for a fist-sized muscle. 2. Broken heart causes heart attack.
