Oxygen in the alveoli is picked up by hemoglobin in erythrocytes (red blood cells) in the capillaries of an alveolus. The erythrocytes then travel back to the heart through the pulmonary vein and gets pumped to the rest of the body through the left atrium, left ventricle, and the aorta.
It sends oxygen to individual alveoli in your lungs, which sends oxygen to your body's cells.
The oxygen in each breath is circuited to the lungs where the alveoli absorb the oxygen and passed to the blood cells. The blood cells enter the heart where the oxygenated blood is circulated where needed.
Oxygen diffuses through the alveoli in the lungs into the blood stream. Here, haemoglobin bonds with the oxygen, forming oxy-haemoglobin. When needed, the oxy-haemoglobin breaks down to form oxygen and haemoglobin to unload the oxygen into nearby cells.
Oxygen is transferred to blood cells in the capillaries around the alveoli. It diffuses from the alveoli into the bloodstream, and to the hemoglobin molecule.
When you inhale in the lungs the air goes into little sacks called alveoli. In the alveoli gaseous exchange occurs this is when the carbon dioxide from the capillaries is exchanged for the oxygen you inhaled. When in the capillaries the red blood cells absorbs the oxygen and transports it around the body until all the oxygen is absorbed by the body it is then brought backed to the lungs where gaseous exchange occurs again.

Oxygen diffuses from the alveoli into the blood due to higher PO2 (partial pressure of oxygen) levels in the alveoli than in the blood.
External respiration is the exchange of oxygen and carbon dioxide between the lungs, body and the outside environment; the breathing process known as inhalation and exhalation. Upon inhalation, air enters the body and is warmed, moistened, and filtered as it passes to the alveoli of the lungs. Oxygen diffuses from the alveoli to the bloodstream, then into the red blood cells. Simultaneously, carbon dioxide in the blood is diffused from the blood to the alveoli, and exhalation expels the carbon dioxide from the alveoli.
The alveoli are the sites of respiration: the oxygen in them provided by the inhaled air diffuses into the blood cells that flow through the capillaries. Carbon dioxide diffuses out of the blood and into the alveoli so it can be exhaled. The capillaries provide a way for the blood to reach the alveoli. Hope this helps
The exchange of oxygen and carbon dioxide happens in between the alveoli and then through the walls of the capillaries and then into the blood. The oxygen is then picked up by hemoglobin in the red blood cells and sent to all body cells. While this is happening the carbon dioxide is transported back from the body cells and into the blood. It diffuses through the walls of the capillaries and into the walls of the alveoli. Carbon dioxide leaves your body whenever you breathe out.
The lungs take in Oxygen which is carried by the blood to the cells of our body in order for respiration to occur and we get energy. The transfer of Oxygen to the blood happens in the Alveoli. The Alveoli are little bumpy ball like things at the end of the bronchioles in our lungs. The Carbon Dioxide is taken out of our blood in the Alveoli too.
