Gas exchange between the body and the environment occurs in the lungs.
Diffusion occurs in the leaf to facilitate the movement of gases such as carbon dioxide and oxygen. These gases diffuse in and out of the leaf through small openings called stomata, allowing for photosynthesis and respiration processes to take place effectively. This exchange of gases helps the leaf to obtain the necessary substances for energy production and to release waste products.

The exchange of oxygen and carbon dioxide between the body and the surrounding air takes place primarily in the lungs. In the lungs, oxygen from the air is taken up into the blood by tiny air sacs called alveoli and carbon dioxide is released from the blood into the air to be exhaled.
Solids have a definite shape and do not easily take the shape of their container due to the strong intermolecular forces between their particles, which keep them locked in place. This characteristic distinguishes solids from liquids and gases, which can flow and take the shape of their container.
Gases takes place by nasal passage go to lungs to purifi.
Gaseous waste is expelled from the body primarily through respiration. A process called gas exchange takes place in the lungs. With every breath we take, some quantity of the waste gases (like carbon dioxide, or CO2) in our blood is exchanged for oxygen (O2) in the air inspired. Note that anything else in the air that we inhale can be carried across and into the blood.
Alveoli.
Cnidaria don't have gills or lungs, but they take in oxygen from surrounding water through diffusion.
Oxygen and carbon dioxide are exchanged by way of the circulatory system. Cells use oxygen for energy and produce carbon dioxide as a waste. Capillaries are where this exchange occurs. Veins carry this product back to the heart. This blood goes to the lungs were you blow off the carbon dioxide and take in oxygen. So the circulatory system and lungs work together to exchange gases.
The lungs exchange gases with the air. The lungs will take in fresh, oxygen filled blood and circulate it throughout the body. The lungs will then expel the air, and start the process all over again.

conduction take place in solids and gases
The lungs allow our blood to absorb oxygen and expel carbon dioxide and other gases. When we exhale, those gases are pushed out of our body.
The respiratory system is a vehicle for gases to get from the atmosphere into the body, but the respiratory system itself does not transport oxygen and carbon dioxide to and from body cells.When oxygen reaches the alveolar region of the lungs (that's to say, where the alveoli are located) oxygen is exchanged with red blood cells that take the oxygen to the rest of the body.
