Respiration
gas exchange
lunges
the alveoli in the lungs and the capillaries in the body
respiratory
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
The alveoli
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.
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.
