How are surface area of lungs important for gaseous exchange

Larger surface area to volume ratio increases the amount of area in contact with air in the lungs to allow for uptake of oxygen and release of carbon dioxide. Basically with a larger surface area, carbon dioxide in the blood capillaries are easily released and oxygen is easily taken up, increasing efficiency of gaseous exchange.

Explanation:

poor water quality affects most estuarine organisms, including commercially important fish and shellfish. the pollutants that have the greatest impact on the health of estuaries include toxic substances like chemicals and heavy metals, nutrient pollution (or eutrophication), and pathogens such as bacteria or viruses.
