From the Alveoli, it transfers to red blood cells, which travels through the circulation and reaches the heart.

What happens to the oxygen when it reaches the alveoli?
oxygen enters the blood and carbon dioxide
Is the blood arriving at the alveoli from the heart rich in oxygen?
No, but the blood leaving is.
How does the heart get oxygen from the blood?
The heart gets the oxygen from the red blood cells that "trade" CO2 for oxygen in the lungs and travels back up to the heart and gives the heart a bit of the oxygen and then gives the rest of the oxygen to the other organs (like the alveoli and the liver and the gut ect)
What is the main unit of oxygen exchange in the human lung?
the capillary's, they are based on the alveoli and they pass oxygen from the alveoli sacks through to the blood stream- ready to go to the heart and be pumped around the body
Do the lungs bring oxygen into blood?
When air reaches lungs which has thousands small sacks called alveoli the oxygen is difussed to blood capillaries that line alveolar wall.
Where in the lungs does gas exchange take place?
In the alveoli (also called air sac) is the capillary-rich sac in the lungs where the exchange of oxygen and carbon dioxide takes place by diffusion. The oxygen poor blood goes from the right ventricle and into the lungs where the co2 is traded for Oxygen in the alveoli and back through the heart and out to the body.
How can you the oxygen you bring into your body get into the circulatory system?
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.
How does the oxygen change to carbon dioxide?
The primary function of the respiratory system is to exchange oxygen and carbon dioxide. Inhaled oxygenenters the lungs and reaches the alveoli. Oxygen passes quickly through this air-blood barrier into the blood in the capillaries. Similarly, carbon dioxide passes from the blood into the alveoli and is then exhaled.
How do alveoli and capillaries help to get oxygen?
The alveoli is the point where the waste product of respiration (carbon dioxide) and oxygen are diffused into or out of the blood. Oxygen diffuses into the blood stream and are carried to the heart and carbon dioxide is diffused out of the lungs and expired. The alveoli have moist walls and are close to the capillaries which speeds up the process.
Where does blood get new oxygen?
In the lungs. The blood is pumped from the right side of the heart to the lungs. Air moves into the trachea, the bronchi and finally to the alveoli. From the alveoli oxygen diffuses into the microcapilaries (small blood vessels) of the lungs.
What job is the lungs allow the blood to do?
Exchange oxygen and carbon dioxide in the alveoli of the lung, then transfer it to the heart
What is the pathway of an oxygen molecule from the atmosphere to its combination with a hemoglobin molecule?
Oxygen reaches the hemoglobin in the blood cells by entering the lungs. The key area of the lungs where the transfer of oxygen and carbon dioxide is made is called the alveoli. The Alveoli has very thin cell walls which allow oxygen and carbon dioxide to pass freely in and out of the blood stream.
