Study the oxygen-haemoglobin dissociation curve given in the figure and select the correct statements regarding it:
.svg)
| I: | The p50 is the pressure at which haemoglobin is 50% saturated which corresponds to about 27 mmHg on the X-axis. |
| II: | A right shift of the curve means haemoglobin holds less tightly onto oxygen and delivers more oxygen to the tissues at a given arterial oxygen pressure. |

Select the incorrect statement among the following:
1. The nasal cavity leads to the larynx, an intersection where the paths for food and air cross.
2. Air enters through the nostrils and is then filtered by hair, warmed, humidified, and sampled for odors as it flows through a maze of spaces in the nasal cavity.
3. The trachea branches into two bronchi, one leading to each lung.
4. During the swallowing of food glottis can be covered by a thin elastic cartilaginous flap called epiglottis.
