Insects have a unique respiratory system made up of small tubes called tracheae. The tracheae connect all parts of the body to small openings on the surface of the insect. Oxygen and carbon dioxide are transported through the tracheae (which the site of gaseous exchange) and from the tracheae to the blood of the insect by diffusion.
Insects have small tubes called tracheae that deliver oxygen directly to their cells for respiration. The gaseous exchange occurs through tiny openings in the body called spiracles, which allow oxygen to enter the tracheal system and carbon dioxide to exit.

Why is Transpiration is the inevitable consequence of gaseous exchange in land plants?
Transpiration is the inevitable consequence of gaseous exchange in land plants because it is the process by which plants lose water vapor through their leaves while exchanging gases with the atmosphere. As plants take in carbon dioxide for photosynthesis through their stomata, water vapor is released. This helps maintain the plant's internal water balance and allows the exchange of gases necessary for photosynthesis and respiration.
What is pneumatophores?
Pneumatophores are specialized root structures that help certain plants, like mangroves, obtain oxygen in waterlogged soils. These structures grow vertically above the soil or water surface, allowing for gas exchange with the atmosphere. This adaptation is essential for the survival of these plants in oxygen-poor environments.
How does the leaf gaseous exchange take place?
Leaf gaseous exchange occurs through tiny pores called stomata on the surface of leaves. During photosynthesis, carbon dioxide enters the leaf through the stomata, while oxygen and water vapor exit the leaf through the same pores. This exchange of gases is crucial for the process of photosynthesis and respiration in plants.
What are small sac-like structures that is the site of gas exchange in the lungs?
The small sac-like structures that are the site of gas exchange in the lungs are called alveoli. They are responsible for the exchange of oxygen and carbon dioxide between the air we breathe and our bloodstream, allowing for efficient respiration.
What is the definition of spiracles?
Spiracles are small openings found on the sides of the body of insects and some other arthropods that are used for breathing. They allow for the exchange of gases, such as oxygen and carbon dioxide, between the organism and its environment.
Where is the site for gaseous exchange?
The site for gaseous exchange is the lungs. Carbon dioxide is exhaled and is substituted for oxygen which is inhaled.
Where in the lungs does gaseous exchange take place?
alveoli is the site for gaseous exchange. They are the air filled sacs where carbon dioxide and oxygen is exchanged
What is the name for exchange of gas in the lungs?
gaseous exchange
What is the difference between ventilation and gaseous exchange?
Gaseous exchange is a natural process, ventilation is a forced process.
What exchange takes place in the lungs?
gaseous exchange - in the alveolis
