Answer 1

11. Lung atelectosis is a condition where lungs are collasped due to failure of expansion. Hence, option d is correct.

12. The entries sequence of events involved in the exchange of oxygen and carbon dioxide between the cells and external environment is called internal respiration. Hence, option b is correct.

13. Pharynx is the common structure between respiratory and digestive system. Hence, option c is correct.

14. The inspiratory muscle include diaphragm and external intercoastal muscles. Hence, option b is correct.

15. When the diaphragm contracts during inspiration, the volume of thoracic increases . Hence, option a is correct
