What organ..?
Deoxygenated blood leaves the heart by way of the Pulmonary Artery. It passes through the lungs losing carbon dioxide and absorbing oxygen by conversions in the haemoglobin. The oxygen rich blood returns to the heart via the Pulmonary Vein. From the heart it goes to the body, The most oxygen rich blood would be in the Pulmonary Vein just after it leaves the lungs.
A pulmonary embolism is a sudden blockage in a lung artery, usually due to a blood clot that traveled to the lung.
The oxygen is taken from the alveoli in the lungs.

The oxygen molecule is inhaled (breathed in) through the left nostril or the mouth and then goes down the trachea (windpipe) and into the bronchioles and into the alveoli (both are parts of the lung). Then the blood meets up with the oxygen molecules and turns it into oxygenated blood. This blood is fed into the blood stream and go down the arteries, then capillaries, then into the muscle where they help it work. The blood is deoxygenated and then the blood goes to the heart to be pumped round the body again and the oxygen is taken up the same way it came down and is exhaled. I hope this helped :)
Oxygen diffuses from the alveoli of the lungs into the blood. Carbon dioxide diffuses from the blood into the alveoli of the lung where is will be exhaled.
When blood is pumped to the lung, carbon dioxide diffuses from the blood into the alveolus. The pumonary artery carries the blood from the heart to the lungs.
Oxygen diffuses from any place there is a lot of it to any place where there is less. In the body, it diffuses from the air in the alveoli of the lungs, through the lung and capillary walls and into the blood, where it is taken up by the haemoglobin of the red blood cells. When the bood reaches the body tissues it diffuses out of the blood and into the cells.
The blood that leaves the right side of the heart is passed into the pulmonary arteries. This blood is oxygenated in the lungs and passes through the pulmonary veins into the left side of the heart.
it comes from carbon oxidizing through fire. It also comes from a lot of other places. Carbon dioxide is a waste product of cellular respiration. It diffuses into the blood from the cells and travels to the lung where it is exhaled into the air.
absorpition of oxygen from the blood into the lung
Each lung is suspended in its own pleural cavity and rests on the muscular diaphragm. The medial surface has a hilus (indentation) where the bronchi enter. Because of the shape and location of the heart, the lungs differ in size and shape. The left lung is smaller with 2 lobes, the right has 3 lobes. Lungs are mostly air spaces and connective tissue. The lung contains the air sacs where oxygen diffuses from air sacs into the blood vessels and waste carbon dioxide diffuses from the blood vessels into the air sacs. Each lung exists in a pleural cavity, a serous membrane compartment which prevents friction damage as the lungs expand and contract during breathing. The visceral pleura is the membrane fused to the outer surface of the lung; the parietal pleura is the membrane which lines the body wall. Between the two membranes in the pleural fluid.

If I'm not wrong, the O2 is carried from your lungs by red blood cells, then is passed to the muscles which need it through the walls of the blood vessels, while they take CO2 from the muscles to bring it back to the lungs to expel. So... it occurs through the bloodstream and the walls of the blood vessels (capillary vessels etc.)
The lung takes carbon dioxide out of your blood and replaces it with oxygen.
red blood
In the lungs? Can you please be more specific. There are lung tissues and sacs that aid in gas exchange called alveoli, but there really isn't a specific lung cell.
Gaseous exchange is the process where we get the oxygen we need into our bodies and the Carbon dioxide, that we produce during respiration, out. This process takes place in little sacks of the lungs called alveolus. These Alveolus have several features that encourage gasseos exchange to take place including moist, one cell thick walls. The gases move by the process of deffusion. Deffusion is when gasses spread from an area of high concentratio to low concentration. The oxygen diffuses into the blood and the carbon diffuses int the lung.(Red blood cells exchange carbon dioxide for oxygen. -TRIP)Read more: What_happens_during_gas_exchange
