Henry's law
Oxygen is exchanged from the air in the alveoli into the blood in the capillaries, while carbon dioxide is exchanged from the blood in the capillaries into the air in the alveoli during the process of respiration.
The greatest partial pressure of CO2 is typically found in the alveoli of the lungs, where CO2 is exchanged between the bloodstream and the air we breathe. This is the point where oxygen is taken in and carbon dioxide is released.
CO2 exchanged to blood through capillaries and blood to alveoli
The respiratory and circulatory systems are involved in the exchange of gases between the alveoli and blood. The alveoli are part of the lungs, and their surrounding capillaries are part of the circulatory system.
Wherever capillaries are found, these are places where nutrients and wastes are exchanged.
diffusion
oxygen and carbon dioxide are exchanged in alveoli (singular alveolus).
air exchange takes place at the juction of blood cappileries and alveoli where the pressure of air is high in alveoli and low in blood so air from alveoli rush into blood and CO2 from blood rush in to alveoli which is then breath out
Oxygen is exchanged from the air in the alveoli into the blood in the capillaries, while carbon dioxide is exchanged from the blood in the capillaries into the air in the alveoli during the process of respiration.

Alveoli
Mostly oxygen & carbon dioxide - but also some nitrogen.
Oxygen (O2) is exchanged for carbon dioxide (CO2) in the lungs. In the alveoli, tiny air sacs in the lungs, oxygen from the air is transferred into the bloodstream while carbon dioxide from the blood is released into the air to be exhaled.
