Draw a flow chart showing the air passage in the human respiratory system. Br (Trachea, nasal cavity, nasopharynx, bronchi, nos-trils, alveoli, bronchioles, larynx)

Choose the ODD one out from the following terms given and name the CATEGORY to which the others belong: Nasal cavity, Oral cavity, Larynx, Pharynx, Trachea

Which of these statements are fasle regarding the human respiratory regarding the human respiratory system ? (a) The nasal chamber opens into the pharynx . (b) Trachea, bronchus and initial bronchioles are supproted by complete cartilaginous rings. (c ) The branching network of bronchi, bronchioles and alveoli comprises the lungs. (d) Pleural fluid increase friction on the lung surface.

Draw the structure of lungs and label the fol- lowing parts in it. (1) Nasal cavity (2) Epiglottis (3) Lungs (4) Larynx and vocal cords (5) Trachea (6) Diaphragm (7) Bronchus (8) Alveoli

Which of the following are correct for pharynx? I. It is a junction of buccal cavity, nasal chamber, Eustachian tube and trachea. II. It is the aprerture, which leads into the oesophaus. III. It is the structure, which allows air to enter into trachea.

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.

S to Z are structures of the human respiratory system. Arrange them to show the order in which air from outside travels through the respiratory system to reach the gaseous exchange surface in the lungs. S: Bronchioles U: Nostrils W: Epiglottis Y: Trachea T: Bronchi V: Pharynx X: Larynx Z: Alveoli

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 ?
