External gills, tracheae, and lungs all share which of the following ...
Gas-exchange System
External gills, tracheae, and lungs are all part of the gas-exchange system in different organisms. This system allows for the exchange of gases, specifically oxygen (O2) and carbon dioxide (CO2), between an organism and its environment.

Exchange of CO2 and O2
All three structures - external gills, tracheae, and lungs - are involved in the exchange of both CO2 and O2.

Increased Surface Area
One of the key characteristics shared by these structures is the increase in surface area for diffusion. This increased surface area allows for more efficient gas exchange, as it provides a larger contact area between the respiratory organs and the environment.

External Gills
External gills are found in aquatic organisms such as fish and some amphibians. They are located outside the body and are used to extract oxygen from water. The gills are composed of thin, filament-like structures that are richly supplied with blood vessels. These structures increase the surface area available for gas exchange.

Tracheae
Tracheae are found in insects and some other arthropods. They are a network of tubes that deliver oxygen directly to the cells. The tracheae open to the outside through tiny openings called spiracles. Oxygen diffuses through the spiracles and travels through the tracheae to reach the body cells. This system also increases the surface area available for gas exchange.

Lungs
Lungs are found in vertebrates, including mammals, reptiles, and birds. They are internal organs involved in the exchange of gases between the blood and the external environment. Lungs consist of numerous tiny air sacs called alveoli, which greatly increase the surface area for gas exchange. Oxygen from the inhaled air diffuses into the bloodstream, while carbon dioxide is removed from the blood and exhaled.

Conclusion
In summary, external gills, tracheae, and lungs are all part of the gas-exchange system and share the characteristics of being involved in gas exchange, facilitating the exchange of both CO2 and O2, and increasing the surface area available for diffusion.
