Expiration is normally brought about by the relaxation of inspiratory muscles. Oxyhaemoglobin can hold much less CO2 in the form of carbaminohemoglobin than what oxyhaemoglobin can. Aperson cannot expel all the air from the lungs even after forceful expiration. The collie of air which remains in the lungs after the most forceful expiration is called residual volume. It is about 1100 L to 1200 mL. A rise in pCO2 decrease the O2 affinity of hemoglobin.

Explanation:
(i) Expiration is normally brought about by the relaxation of inspiratory muscles. - False
Expiration is primarily brought about by the contraction of expiratory muscles, such as the internal intercostal muscles and the abdominal muscles. These muscles contract and decrease the size of the thoracic cavity, causing air to be expelled from the lungs.
(ii) Oxyhaemoglobin can hold much less carbon dioxide in the form of carbaminohaemoglobin than what deoxyhaemoglobin can. - False
Oxyhaemoglobin has a lower affinity for carbon dioxide than deoxyhaemoglobin. This means that oxyhaemoglobin releases carbon dioxide more readily and can hold less carbon dioxide in the form of carbaminohaemoglobin.
(iii) A person can expel air from the lungs by a forceful expiration. - True
A person can expel air from the lungs by forcefully contracting the expiratory muscles. This can be done voluntarily or involuntarily, such as during coughing or sneezing.
(iv) A rise in PCO2 increases the oxygen-affinity of haemoglobin. - False
A rise in PCO2 (partial pressure of carbon dioxide) decreases the oxygen-affinity of haemoglobin. This is known as the Bohr effect. When PCO2 increases, it leads to a decrease in pH, which causes a conformational change in the haemoglobin molecule, reducing its affinity for oxygen. This allows for the release of oxygen to the tissues.
Therefore, the correct option is (i) F, (ii) F, (iii) T, (iv) F.

Therefore, the correct option is (i) F, (ii) F, (iii) T, (iv) F.
