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.
by diffusion in the trachea
in their specialized external gills
The stomata are meant for gaseous exchange, however transpiration also occurs when they are open.
Photosynthesis, gaseous exchange and transpiration
pneumatophores are lateral roots that grow upward (negative geotropism) for varying distances and function as the site of oxygen intake for the submerged primary...or they are a specialized root of certain swamp plants, such as the mangrove, that branches upwards, rising above ground, and undergoes gaseous exchange with the atmosphere.Pneumatophores are aerial roots that are specialized for gaseous exchange and are found in swamp plants and mangroves.
pneumatophores helps in respiration and gaseous exchange , compensates lack of oxygen in soil in marshy areas
alveoli
The site for gaseous exchange is the lungs. Carbon dioxide is exhaled and is substituted for oxygen which is inhaled.
alveoli is the site for gaseous exchange. They are the air filled sacs where carbon dioxide and oxygen is exchanged
Help in gaseous exchange
gaseous exchange
Gaseous exchange is a natural process, ventilation is a forced process.
