Gas exchange or respiration takes place at a respiratory surface; a boundary between the external environment and the interior of the body. For unicellular organisms the respiratory surface is simply ...

Respiration is the process of releasing energy from food. Like human beings and other animals, plants also need oxygen from the environment and release carbon dioxide. This shows that even plants ...

Inhalation and exhalation is the same as breathing or ventilation and is a physical process which moves air into and out of your lungs. Respiration is not the same as breathing, and is a chemical ...

Short-term high-frequency nasal ventilation (HFNV) of preterm neonates provides acceptable gas exchange compared to endotracheal intubation and intermittent mandatory ventilation (IMV). Whether ...

This paper seeks to identify the factors which have the greatest effect on gas diffusion rates into animal burrows, and in turn on the maximum size of burrowing animals which may rely on simple burrow ...

Infant mortality caused by respiratory distress syndrome in the United States decreased from ∼268 in 100,000 live births in 1971 to 98 in 100,000 live births in 1985 (1) and 17 in 100,000 live births ...

The morphometrics of the respiratory system, voluntary emersion behaviour, and gas exchange during immersion and emersion were examined in the amphibious, intertidal crab Hemigrapsus nudus. The area ...

Internal browning of pears stored under low oxygen conditions is related to restricted gas exchange inside the fruit, according to a study published March 7th in the open-access journal PLoS ...
