Heart has two sides (4chambers) separated by a septum.One side it collects the impure blood ie from all the parts of our body and pumps it to lungs. At lungs through alveoli the co2 diffuses out and oxygen enters the blood. this pure blood (oxygenated blood) enters the other side of heart from where it is pumped to all body parts AND cycle continues.
the gas the body needs for the lungs and you to breathe is oxygen
The blood carries carbon dioxide or CO2 as it moves from the heart to the lungs.
Oxygen
You use your lungs to breath. Your heart pumps the blood round your body (including into and out of the lungs where gas exchange occurs when you breath).
Oxygen
The lungs hold air that is breathed in. Oxygen gas in the air moves into the blood. The heart pumps to transports this oxygenated blood to cells in the body that need it to produce energy.
How much oxygen the blood is receiving (also how well the lungs are functioning) and carrying from the heart to the body's systems.
The lungs provide for gas exchange between the blood and the air. So when your heart pumps blood to your lungs, the lungs provide an area for blood to absorb oxygen from the air we breath in and to rid its self of excess carbon dioxide, which is then exhaled.

Carbon Dioxide
The lungs hold air that is breathed in. Oxygen gas in the air moves into the blood. The heart pumps to transports this oxygenated blood to cells in the body that need it to produce energy.
The pulmonary artery takes carbon dioxide (CO2) from the heart to the lungs. Oxygen is then carried back to the heart by the pulmonary vein. Finally, the aorta/arteries carry oxygen to the body.
Carbon Dioxide (CO2)
It's referred to as Carbon dioxide. It is the main cellular waste product that is carried in the blood to the lungs through the heart.
The gas you need to stay alive is Oxygen, you need oxygen to carry vital functions of body, when you inhale oxygen, its goes directly into the lungs and through alveolis, which are present in lungs oxygen get absorbed into blood which is then taken to heart and heart pumps the blood to each and every part and organ of the body, so like this your body works.
