They die because they are unable to produce energy and function. And shrink
Blood is specifically what brings oxygen to cells. Since oxygen is exchanged between blood vessels and surrounding tissue by osmosis, oxygen-starved cells will rapidly receive this oxygen.
Once oxygenated blood reaches the capillaries, the velocity of the blood is very slow - which favours the exchange of oxygen. Oxygen therefore diffuses across the walls of the capillaries into the tissues that need it.
oxygen enters the blood and carbon dioxide
Anemia is a disease where the blood doesn't carry enough oxygen, due to either a lack of blood cells or hemoglobin, or damage to the blood cells or hemoglobin.
when the blood reaches to the tissues then the cells embedded inside it absorbs the oxygen from the haemoglobin present inside the blood and blood absorbs all the waste material from the tissues like CO2,etc.then the blood passes the waste materials to the lungs AND AFTERWARDS it comes out through the process of respiration.

The oxyhaemoglobin will break down and oxygen will release. :)
oxygen enters the blood and carbon dioxide
Blood flows through veins after delivering oxygen to the body.
The blood is oxygenated that is oxygen which has been inhaled is added to the blood and the blood then transports it to other body parts.
When blood reaches the tissues, cells, and organs via the capillaries, materials diffuse across the capillary wall so that the cells, tissues, and organs receive nutrients and oxygen, and eliminate wastes.
The red blood cells pick it up from the air and take it through the blood stream to the cells in the body.
As blood passes through lungs, there is exchange of oxygen and carbon bi oxide, from high concentration to low concentration and oxygen enters the blood from air to blood to make it oxygen rich.
Oxygen reaches all parts of an animal's body when it inhales via the lungs, and the oxygen enters the blood stream. The heart then pumps these oxygenated blood cells to the rest of the body.
the kidneys clean it by removing the waste from the blood
When your oxygen saturation levels drop, your blood is not carrying enough oxygen to provide your body the levels it needs. If they drop low enough, your body will shut down and you can die. If you are hooked to a ventilator, this will help the body increase the oxygen saturation levels in your blood, potentially saving your life.
The oxygen poor blood (not enough oxygen) goes to the lungs to get more oxygen to turn into oxygen rich blood (has plenty of oxygen)
