Which of the following statement(s) is (are) true about respiration? A) During inhalation, ribs move inward and the diaphragm is raised B) In the alveoli, exchange of gases takes place i.e., oxygen from alveolar air diffuses into blood and carbon dioxide from blood into alveolar air sacsC) Haemoglobin has greater affinity for carbon dioxide than oxygen Alveoli does not help in
increasing surface area for exchange of gases
D) None
