The concentration of oxygen in the alveolus is low because it is continuously being taken up by the blood in the pulmonary capillaries for oxygenation. As a result, the oxygen level in the alveolus decreases, creating a concentration gradient that promotes the diffusion of oxygen into the bloodstream.

Diffusion is when a molecules spread from an area of high concentration to an area of low concentration so the oxygen will move away from the other oxygen molecules that were in a high concentration to an area with a lower concentration. An example you would relate this to would be if you were to put a drop of food coloring into a glass of water.
the movement of molecules from an area of high concentration to an area of low concentration. In the case of oxygen entering a cell, it moves from an area of high oxygen concentration outside the cell to an area of low oxygen concentration inside the cell. This process helps maintain the balance of oxygen levels necessary for cellular respiration.
Oxygen and hydrogen gases are released.
Oxygen diffuses from the tracheoles into the body cells through a process called passive diffusion. This process relies on a concentration gradient, where oxygen moves from an area of high concentration in the tracheoles to an area of low concentration in the body cells.
Oxygen diffuses from the alveolus into the blood capillary due to the concentration gradient - from high to low concentration. This process allows oxygen to enter the bloodstream and be transported to the body's tissues for utilization.
Oxygen moves from high concentration in the lungs to low concentration in the blood for delivery to tissues, while carbon dioxide moves from high concentration in the tissues to low concentration in the lungs for removal from the body.
Oxygen and carbon dioxide are transported across the capillary membrane by diffusion. Oxygen moves from areas of high concentration in the alveoli to areas of low concentration in the blood, while carbon dioxide moves from areas of high concentration in the blood to areas of low concentration in the alveoli. This exchange occurs due to differences in partial pressure.
Oxygen diffuses into the blood in the lungs and binds to the hemoglobin since the oxygen concentration is high and the carbon dioxide concentration is low. The blood is pumped to the body. The hemoglobin releases the oxygen to the tissues because here, the concentration of oxygen is low and that of carbon dioxide is high.
From areas of high oxygen concentration to low oxygen concentration, diffusion occurs as oxygen molecules move down their concentration gradient, from where there is more oxygen to where there is less oxygen. This process enables the cells in the body to take in oxygen and use it for cellular respiration, supporting various physiological functions.

Apoxemia is an abnormally low concentration of oxygen in arterial blood.
The heart is constantly pumping blood around the body. blood entering the lungs is deoxygenated and high in C02 The air in the alveoli has a high oxygen concentration and in comparison is low in C02 This sets up a concentration gradient. This causes oxygen to diffuse into the RBC and C02 to diffuse out in order to try balance the concentration. This balance is maintained by breathing, taking away the C02 in the lungs and bringing in fresh O2 and the constant pumping of blood, bringing more deoxygeneate blood into the lungs
The lowest concentration of oxygen in the body is in the venous blood returning to the heart. This blood has delivered oxygen to tissues and organs and is now returning to the heart to pick up more oxygen in the lungs through respiration.
