Respiration
gas exchange
The two breathing organs where gas exchange occurs in the body are the lungs. Within the lungs, tiny air sacs called alveoli facilitate the exchange of oxygen and carbon dioxide between the air and the bloodstream. This process is essential for supplying oxygen to the body and removing carbon dioxide, a waste product of metabolism.

the alveoli in the lungs and the capillaries in the body
The capillaries are responsible for gas and nutrient exchange with each of the body's cells. These tiny blood vessels have thin walls that allow for the exchange of oxygen, carbon dioxide, and nutrients between the blood and the surrounding tissues.
suffocation
It's because a process called gas exchange has taken place in the fish's body. Oxygenated blood is pumped throughout the body, and the cells in the body take out oxygen and put in carbon dioxide (gas exchange). The blood returning to the heart of the fish is deoxygenated, and it will have to eventually go to the gills. There, the carbon dioxide (CO2) will get dumped into the water and oxygen (O2) will be picked up from the water at the same time in another gas exchange.
The alveoli
cutaneous gas exchange
Carbon dioxide (CO2). It is exchanged with Oxygen (O), which is inhaled. This exchange is called the Gas Exchange and it happens in the Aveolus.
