Gas exchange primarily occurs in the alveoli of the lungs. The alveoli are tiny air sacs where oxygen from the inhaled air diffuses into the bloodstream and carbon dioxide from the blood diffuses into the alveoli to be exhaled. This exchange of gases is facilitated by the thin walls of the alveoli and the surrounding capillaries.
Each alveolus is surrounded by a network of capillaries, which are tiny blood vessels responsible for the exchange of oxygen and carbon dioxide with the surrounding tissues. This network allows efficient gas exchange to occur in the lungs.
The capillary is known as the functional unit of the cardiovascular system. Capillaries are small blood vessels where gas exchange and nutrient exchange occur between the blood and tissues. This exchange is essential for delivering oxygen and nutrients to cells and removing waste products.
Gas exchange occurs in the alveoli of the lungs. These tiny air sacs are surrounded by capillaries where oxygen from the air can enter the bloodstream and carbon dioxide can be removed from the blood.
In prawns, gas exchange occurs through specialized gill structures. These gills are rich in blood vessels and allow for the exchange of oxygen and carbon dioxide between the prawn's respiratory system and the surrounding water. The thin, permeable surface of the gills facilitates efficient gas exchange.
Oxygen exchange takes place in the capillaries, which are the smallest blood vessels in the body.

The exchange of gases occurs at the ends of the airways in the lungs. Here tiny sacs called alveoli connect with tiny blood vessels and here exhaust gas [carbon dioxide] is exchanged for fresh gas [oxygen].
The gas occurs by simple diffusion through the cells.
