compare to lungs the pH is more in cells.so that the myoglobin in blood have more affinity towards oxygen,SO THAT OXYGEN IS TRANSFERRED.AND THE CO2 PRODUCED IN THE CELLS WILL BIND WITH HAEMOGLOBIN AND WILL REACH LUNGS.THE INCREASED pH IN CELLS DUE TO THE CO2 WILL BIND WITH H2O PRESENT IN WATER WILL PRODUCE CARBONIC ACID.

Oxygen is the substance that moves from the bloodstream to the air via the lungs during respiration. This process occurs in the alveoli of the lungs where oxygen is exchanged for carbon dioxide.
Passive diffusion occurs in the alveoli of the lungs. Oxygen from inhaled air moves across the thin alveolar membrane into the bloodstream, while carbon dioxide moves from the bloodstream into the alveoli to be exhaled.
The small sac-like structures in the lungs are called alveoli. This is where the exchange of oxygen and carbon dioxide occurs with the bloodstream, a process known as gas exchange. Oxygen diffuses from the alveoli into the bloodstream, while carbon dioxide moves from the bloodstream into the alveoli to be exhaled.
Oxygen moves into the lungs where it is absorbed into the bloodstream through tiny air sacs called alveoli.
When you inhale, your diaphragm contracts and moves downward. This action creates a vacuum in your chest cavity, drawing air into your lungs. The expansion of the lungs allows for oxygen to be absorbed into the bloodstream.
This process is called gas exchange. In the lungs, oxygen enters the bloodstream through diffusion across the alveolar membrane, where it binds to hemoglobin in red blood cells for transportation to tissues.
Oxygen moves from the lungs into the bloodstream through a process called diffusion. This occurs at the alveoli, which are small air sacs in the lungs where oxygen and carbon dioxide are exchanged with the blood. Oxygen diffuses from an area of high concentration in the alveoli to an area of lower concentration in the blood, facilitated by the difference in partial pressures.
Oxygen moves into the lungs to the alveoli in the lungs into capillaries into pulmonary veins to the heart then to arteries that go through the rest of the body.
Carbon dioxide is released from your tissues into the bloodstream, where it is transported to the lungs for exhalation. Conversely, oxygen moves from the lungs into the bloodstream and is delivered to the tissues for cellular respiration. Essentially, oxygen goes from the lungs to the tissues, while carbon dioxide travels from the tissues to the lungs.
Oxygen is moving by simple diffusion. It is going from a higher level of oxygen (air) to lower (blood).
Oxygen moves through the body via the bloodstream, carried by red blood cells. It is inhaled into the lungs, where it diffuses from the alveoli into the bloodstream, and then transported to tissues and organs where it is exchanged for carbon dioxide to be exhaled.
