Gaseous exchange is one of the elementary physiological functions whereby gases, mainly oxygen and carbon dioxide, are transferred from an organism to its outer environment and vice-versa. In humans as well as other animals, it takes place mainly in the lungs through respiration. Oxygen dissolved in the air being inhaled during the process of breathing dissolves into the blood stream after being taken inside the alveoli-the small sacs in which the lungs. The end product of respiration is carbon dioxide; it diffuses out from the blood into the alveoli and out from the body through exhalation.

The very basis of cellular metabolism, optimum health, balanced gaseous exchange. Oxygen is crucial for providing cells with the ability to build energy, whereas carbon dioxide requires removal as its removal prevents its accumulation that can contribute to respiratory acidosis.

The gaseous exchange takes place within the stomata structure in the leaves of plants. Because of stomata, plants absorb carbon dioxide to start photosynthesis and emit oxygen since it’s a by-product of respiration. The entire cycle ensures survival as it keeps the atmosphere with a ratio of oxygen and carbon dioxide. The mechanisms of gaseous exchange are crucial in many fields, which vary from medicine, where maladies such as COPD and asthma affect the effectiveness of their respiratory system, to environmental science and climatic condition, where overall composition of gases in the atmosphere balances global warming and health of ecology.
