The lungs are the organ that gets oxygen into the blood.
1) From the heart to the lungs and back, where the blood gets oxygenated.2) From the heart to the diverse organs in the body, where the oxygen gets distributed.
Every organ in the body! No single cell, tissue or organ can survive for very long at all without a constant supply of oxygen. Blood containing oxygen is continually being pumped from the heart to every cell in the body. As the oxygenated blood passes through the body, the oxygen molecules are used up, it then returns to the heart which pumps it to the lungs to be reoxygenated so that the cycle can start all over again.
The spleen. It acts as a filter for blood, but also, as you said, is a reservoir for oxygen rich blood.
In mammals the lungs transfer oxygen from the air into the mammal's blood. The air flows down through a network of bronchial tubes that divide the airflow into smaller and smaller streams. Finally these streams enter the Avioli, which are small sacs with coated in capillaries (blood vessels who's walls are only one or two cells thick). Then the oxygen passes through the capillaries' membrane and into the blood where it is absorbed by the Hemoglobin in the red blood cells.Also, through the reverse process carbon dioxide is expelled from the blood.
All respiring cells in our body need oxygen for respiration, so oxygenated blood has to travel all around the body in order to reach each of these cells.
oxygen rich blood gets pumped out of your heart to your arteries which carries the blood to your muscles. then your muscles use the oxygen. oxygen poor blood goes into your veins to go back into your heart. then it goes through a cycle that takes your blood to your lungs, to get oxygen. this process is repeated.

The blood gets oxygen from the air around us which is made of oxygen. When we breath in, the oxygen is taken into our lungs and then into our blood.
Blood gets oxygen in the cells. This is part of the body system.
