Read the following four statement carefully. (i) Ventral respiratory group of neurons of medulla oblongata can cause both inspiration and expiration. (ii) The part of the respiratory system starting with the external nostrils up to the terminal bronchioles constitutes the respiratory or exchange part of the respiratory system. (iii) During swallowing epiglottis can be covered by a thin elastic cartilaginous flap called glottis to prevent the entry of food into the larynx. (iv) Binding of oxygen with haemoglobin in primarily related of oxygen with haemoglobin is primarily related to partial prssure of O_(2) . Which of the above two statement are correct ?

Which of the following statements about the human respiratory system are INCORRECT ? I. During swallowing , glottis can covered by a thin elastic cartilaginous flap called epiglottis to prevent the entry of food into the larynx. II. The trachea is a straight tube extending up to the mid- thoracic cavity, which divides at the level of the fourth thoracic vertebra into a right and left primary bronchi. III. The trachea , primary secondary and tertiary bronchi, and initial bronchioles are supported by incomplete cartilaginous rings made up of hyaline cartilage. IV. The respiratory part transports the atmospheric air to the alveoli, clear it from foreign particles, humidifies and also brings the air to body temperature.

Which of the following statements are true about respiration ? (i) during inhalation, ribs move inward and diaphragm is raised (ii) the gaseous exchange takes place in the alveoli (iii) haemoglobin has greater affinity for carbon dioxide than oxygen (iv) alveoli increase surface area for the exchange of gases
