Which of the following statements comparing respiration in fish and in mammals is correct?
levacccp [35]

Answer: The following statements <em>comparing respiration in fish and in mammals</em> is correct:

  • The movement of the respiratory medium in mammals is bidirectional, but in fish it is unidirectional.

Explanation:

<u>Breathing </u>is the process by which living beings <em>exchange gases</em> with the external environment. It consists of the <u>entry of oxygen</u> into the body of a living being and the <u>exit of carbon dioxide</u> from it .

Active ventilation occurs if the animal produces the currents (of air or water) that flow to and from its respiratory membranes. It can be :

  • Unidirectional. (air or water is pumped onto the respiratory membrane in only one direction).
  • Bidirectional. (air or water is transported to the respiratory membrane and moves away from it through the same route like in the mammals).
