Gills.
The respiratory system is responsible for exchanging gases, such as oxygen and carbon dioxide, in all organisms. This process occurs through specialized respiratory structures like lungs in mammals, gills in fish, and tracheal systems in insects.
Some aquatic annelids have something akin to gills, and the others do gas exchange through the body wall. They have no respiratory system as such. Wikipedia has some additional information, and a link is provided.
The leaf is the main photosynthetic organ of a plant, responsible for producing food through the process of photosynthesis. It is typically flat and thin in order to maximize sunlight absorption, and contains various structures such as stomata, veins, and chloroplasts. Leaves play a crucial role in the exchange of gases, transpiration, and plant growth.
The respiratory system is responsible for exchanging gases between the blood and the environment. This process occurs in the alveoli of the lungs, where oxygen is taken up by the blood and carbon dioxide is released from the blood to be exhaled.
Stomata are small openings or pores located on the surface of leaves that allow for the exchange of gases, such as carbon dioxide and oxygen, between the plant and its surroundings. These structures regulate the uptake of carbon dioxide for photosynthesis and the release of oxygen as a byproduct.
This body system that is responsible for the exchange of gases between the blood and the external environment.

The respiratory system is responsible for the exchange of gases between the atmosphere and the blood.
The difference in the partial pressure of the gases in the blood coming to the lungs and the alveoli mediated the gas exchange. Without this difference we wont be able to breathe. Diaphragm in the thoracic cavity plays an important role in exchange of these respiratory gases.
Frogs uses respiratory surfaces which totals to three to exchange gases on its surroundings. The three respiratory surfaces are the skin, its lungs, and the lining of their mouth.
The respiratory system is responsible for exchanging gases, such as oxygen and carbon dioxide, in all organisms. This process occurs through specialized respiratory structures like lungs in mammals, gills in fish, and tracheal systems in insects.
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.
In the lungs, exchange of gases occurs in the alveoli(sing: alveolus).
The alveoli are the structures in the respiratory system responsible for the exchange of oxygen and carbon dioxide. They are located in the lungs and have a thin membrane that allows for gases to be exchanged with the blood vessels.
Aquatic arthropods typically exchange gases through gills. Gills are structures that are rich in blood vessels and provide a large surface area for gas exchange to occur, allowing the arthropods to extract oxygen from the water and release carbon dioxide.
The respiratory system is responsible for bringing gases into and out of the body. It could not perform this exchange, however, without the circulatory system.
During the stage of photosynthesis, the exchange of gases occur in the leaves.
