The exchange of gasses takes place across the Alveoli, which are air spaces surrounded by very small air sacs and have a rich supply of blood, because they are surrounded by capillaries. The lungs are made up of many alveoli which are the respiratory surface. Oxygen diffuses from the alveoli into the blood in the capillaries and carbon dioxide diffuses from the blood in the capillaries into the alveoli.

Gas exchange takes place by book lungs .
Air is a mixture of gases.When we inhale we reduce pressure in our lungs and thus air is diffused in our lungs.This diffusion takes place inside the lungs and between the bronchities.Here the air passage is the trachea/wind pipe.
Lungs: Oxygen and carbon dioxide diffuse across the alveolar walls in the lungs during respiration. Small Intestine: Nutrients like glucose and amino acids diffuse from the intestinal lumen into the bloodstream for absorption. Kidneys: Waste products and excess ions are diffused out of the blood and into the nephrons for excretion in the urine.
Gas exchange takes place inside the lungs in the alveoli. The alveoli are a "grape like" structure at the very end of the respiratory tract. The alveoli are composed of a very thin membrane that separates the blood vessels from the gas chambers. The thin membrane allows diffusion of oxygen into the blood stream and diffusion of carbon dioxide (CO2) out of the blood stream. Once the CO2 has diffused into the alveoli, it is exhaled.
Respiration takes place in body tissues and the lungs be the process of diffusion where CO2 and oxygen are exchanged.Read more: What_is_an_example_of_diffusion_in_living_organisms
The alveolus is suitable for gas diffusion due to its large surface area and thin walls, which allow for efficient exchange of oxygen and carbon dioxide between the air in the lungs and the bloodstream. Additionally, alveoli are surrounded by a dense network of capillaries that facilitate rapid gas exchange.
In mammals diffusion occurs at 2 places in the respiratory system. The first place it occurs is in the lungs. The carbon dioxide from the blood diffuses into the lungs and the oxygen in the lungs diffuses into the blood. The second place where diffusion occurs is at the cell. Carbon dioxide diffuses out of the cell and into the blood whereas oxygen diffuses into the cell from the blood. Glucose is also diffused from the capillary to the respiratory cells, since they need energy to function properly. Remember that diffusion works in a certain way: Molecules in a highly concentrated area will naturally diffuse into an area with lower concentrations of that particular substance, until eventually all of the molecules of that substance are evenly spread out within that area.
diffusion takes place in the alveoli
When we intake air in our lungs, the bronchi present inside our lungs have small openings through which oxygen is diffused in blood vessels and carbon dioxide is diffused out of blood vessels and the blood gets enriched in oxygen content and is moved towards heart from which it is then transported towards various parts of the body in each and every cell. The cells then diffuses oxygen from blood to their power house called mitochondria for power production in form of energy and 'by product' i.e. carbon dioxide is then diffused back in blood which then route towards heart and from heart it is then taken to lungs and he whole process is repeated again and again.
