Which of the following statement(s) is (are) true about respiration?
(i) During inhalation, ribs move inward and diaphragm is raised

(iii) Haemoglobin has greater affinity for carbon dioxide than oxygen
(iv) Alveoli increase surface area for exchange of gases
(a) (i) and (iv) (b) (ii) and (iii) (c) (i) and (iii) (d) (ii) and (iv)
Answers
Answer:
hey mate,
During inhalation, the rib cage moves upward and outward, and the diaphragm moves downward.
During inhalation, the rib cage moves upward and outward, and the diaphragm moves downward. During exhalation, the ribs and diaphragm return to their original resting position.
During inhalation, the rib cage moves upward and outward, and the diaphragm moves downward. During exhalation, the ribs and diaphragm return to their original resting position. Alveoli increase the surface area for the exchange of gases and the exchange of oxygen to carbon dioxide occurs in the alveoli itself.
During inhalation, the rib cage moves upward and outward, and the diaphragm moves downward. During exhalation, the ribs and diaphragm return to their original resting position. Alveoli increase the surface area for the exchange of gases and the exchange of oxygen to carbon dioxide occurs in the alveoli itself. Hemoglobin has a greater affinity for oxygen than carbon dioxide which allows gas exchange to occur in the lungs.
