By smoking you reduce the amount of oxygen carried in the bloodstream because one of the gases generated by the burning of the tobacco is carbon monoxide. This gas combines with the haemoglobin in the red blood cells in the same way that oxygen does. But when this happens the oxygen-carrying power is obviously reduced. This is why carbon monoxide is a poison.
It is the supply of oxygen to the heart; the oxygen is carried by the blood. When there's insufficient blood supply, oxygen supply is low too, and angina results. See http://en.wikipedia.org/wiki/Angina_pectoris
Smoking can weaken the lungs and reduce breathing capacity. Also smoking can reduce oxygen level of blood thus blood can not carry enough oxygen to the necessary organ.
oxygen
supply oxygen
Oxygen to the heart.
Breathing, would supply the blood with oxygen.
To supply blood with oxygen so the blood can deliver the oxygen throughout the body.
The blood vessels around the brain help supply energy for your brain
supply oxygen to all organs
The coronary blood supply is the arteries which supply the heart itself; in order for the heart to function it needs a good supply of oxygen just the same as any other organ/muscle. Without the coronary blood supply the heart would not be able to pump blood around the body, a disruption in this blood supply would cause a heart attack.
the lungs supply the blood with oxygen, within the lungs there are alveoli which have a very thin membrane which allows oxygen to pass into the capillaries that run into the lungs hope i helped
no, the red blood cells carry less oxygen when the person smokes
