Question

requirements of highly efficient surface for gas exchange

Answer 1

Gaseous exchange describes the process of bringing gas molecules into the body, while removing other gas molecules from the body, with some degree of equivalency between the two (such as one molecule in, one molecule out) in order to make the process as efficient as possible. In humans, we know the gases participating in the exchange are going to be O2 and CO2 because these gases are the fuel and waste products, respectively, of cellular...

Answer 2

• Respiratory surfaces tend to be thin and have a large surface area, structural adaptations that maximize the rate of gas exchange.
• All living cells must be bathed in water to maintain their plasma membranes. ...
• The respiratory surface must supply 02 and expel C02 for the entire body.
