Look at the possible derived shared characteristics, shown in the text box. Think about where these should be placed along the branching tree diagram. Where in the branching tree would you most likely write jaws? Explain your answer.
Answer:
Option (C).
Explanation:
The alveoli is the main site of the exchange of gases in the human beings. The gases gets exchanged between the atmosphere, lungs and the body tissue.
The contraction of external intercostal muscles and diaphragm during inspiration leads to thoracic cavity expansion. This result in decrease in intrapleural pressure as compared with the atmospheric pressure. The air enters in the lungs. The elastic recoiling of the surface tension of airway and the water oppose the alceoli expansion. The surfactant gets adsorb at the water surface. This reduces surface tension, the force that resist expansion. The pulmonary compilance get increase.
Thus, the correct answer is option (C).
