when your body's cells use O2 in cellular respiration they give off Co2 as a waste product which fills up your lungs. when you then inhale O2 into your lungs they enter air sacks made of a thin tissue that allows gasses to pass through. The O2 then diffuses into your blood stream while the Co2 diffuses out. Your lungs are now filled with Co2 in which you exhale wile your body's cell are producing more Co2. You then in hale and the cycle restarts.
O2= oxygen
Co2= carbon dioxide
diffusion= movement of the concentration from high to low

∙ 6y agoWhen oxygen is inhaled, it travels to the lungs. In the lungs, millions of tiny sacs called alveoli intertwine with a network of very small blood vessels. The alveoli allow carbon dioxide from the blood to be exchanged with oxygen in the lungs. The oxygen molecules are bound to hemoglobin, a protein found in red blood cells. From there the circulatory system carries the red blood cells through the body, and the oxygen is carried wherever it is needed.
Air to lung alveoli, across the epithelial [also capillary] barrier-lining of Cells to the heme-groups of hemoglobin found in red-blood-cells. Oxygen containing RBC's are then transported to another set of capillaries located [found] at the/our extremeties.

When these molecules pass through the lungs they pick up oxygen, forming oxy-haemoglobin. When a molecule of this passes a cell which needs oxygen, the oxygen is stripped off, and haemolobin continues on it's journey. Note. Haemoglobin is dark red; oxy-haemoglobin is a brighter red. That's why arterial blood is a brighter red than venous blood.

What happen to the blood in the right atrium?
a little oxygen and a lot of carbon dioxide
Oxygen and carbon dioxide pass back and forth between the alveoli and the blood through?
Oxygen and carbon dioxide easily pass back and forth between the alveoli and the blood through the capillaries.
State two substances that pass into the blood?
Two substances that pass into the blood include oxygen and carbon dioxide. The blood carries fresh oxygen to the cells and tissues and removes waste materials.
Where does oxygen into the blood and carbon dioxide pass out of the blood?
alveoli
How does oxygen cross the cell membrane?
Air is inhaled into the lungs, where oxygen in the air encounters the hemoglobin molecule inside red blood cells, which has the capacity to form a weak attachment to the oxygen, so that oxygen can be easily picked up but also easily released, somewhat in the way that a sponge can pick up or release water. The red blood cells then move through the circulatory system of the body, pumped by the heart, and they arrive in due course in the smallest blood vessels, the capillaries, which have very thin walls. As the red blood cells are giving off oxygen, some of that oxygen will seep out through the thin capillary walls and will then encounter other cells of the body, and can pass through cell membranes by means of osmosis, thus entering the cell.
Which blood vessel does blood oxygen pass through?
Oxygen and other gases pass through the capillaries.
How does oxygen pass from the atmosphere in the alveoli to the blood stream?
Basiclly,The air enters the lungs by traveling down the wind pipe and it goes down the bronchi and bronchioles and into the alveoli.The Alveoli let the oxygen (from the air) pass into the blood streem by leting it pass through a thin membrane.
What happen to the blood in the right atrium?
a little oxygen and a lot of carbon dioxide
Where the blood collects oxygen?
vains pass through the outer layer of the lung and the oxygen (being soluble) passes through and oxygenates the blood
How does oxygen get from your lungs and into the blood?
You breathe the oxygen into your lungs. The oxygen then dissolves into the water lining which is called the alveoli. Finally, the oxygen will cling to the red blood cells as they pass through the alveolar capillaries and now the oxygen is in the blood.
Oxygen and carbon dioxide pass back and forth between the alveoli and the blood through?
Oxygen and carbon dioxide easily pass back and forth between the alveoli and the blood through the capillaries.
What is the bloodvesells function?
The function of the blood vessel is to pass oxygen through the body via the blood.
State two substances that pass into the blood?
Two substances that pass into the blood include oxygen and carbon dioxide. The blood carries fresh oxygen to the cells and tissues and removes waste materials.
How many oxygen molecules does have to pass through from the alveolus to get into the blood?
3 or 4
What is the body organ which oxygen passes through to capillaries?
The alveoli and capillaries in the lungs pass oxygen to the blood. Both have very thin walls, which allow the oxygen to pass from the alveoli to the blood. The capillaries then connect to larger blood vessels, called veins, which bring the oxygenated blood from the lungs to the heart.
Oxygen and nutrients pass from the blood to the bodys tissues through the thin walls of the?
Capillaries
What structure must blood pass through before it enters the right ventricle?
right atrioventricular valve
