Respiratory Organ Flashcards
What is the process of exchanging O2 and CO2 called?
The process of exchange of O2 from the atmosphere with CO2 produced by the cells is called breathing, commonly known as respiration.
What do organisms use O2 for?
Organisms utilize O2 to indirectly break down simple molecules like glucose, amino acids, and fatty acids to derive energy.
What harmful gas is released during catabolic reactions?
Carbon dioxide (CO2) is released during the catabolic reactions.
How do lower invertebrates like sponges and coelenterates exchange gases?
Lower invertebrates like sponges and coelenterates exchange O2 with CO2 by simple diffusion over their entire body surface.
How do earthworms exchange gases?
Earthworms use their moist cuticle to exchange gases.
What structure do insects use to transport air within their body?
Insects have a network of tubes called tracheal tubes to transport atmospheric air within the body.
What are gills used for?
Gills are special vascularized structures used by most aquatic arthropods and mollusks for gas exchange.
What do terrestrial forms use for gas exchange?
Terrestrial forms use vascularized bags called lungs for gas exchange.
How do fish respire?
Fish respire using gills.
What type of respiration do amphibians like frogs use?
Amphibians like frogs can respire through their moist skin, known as cutaneous respiration.
