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

(i) Tidal volume is 500 ml per min (ii) The respiratory rhythm centre lies in the medulla oblongata. (iii) The trachea, primary, secondary and tertiary bronchi, and initial bronchioles are supported by incomplete cartilaginous rings. (iv) The volume of air remaining in the lungs even after a forcible expiration is functional residual capacity. How many of the above statements are correct?

Draw the human respiratory system and label the following parts: (a) Trachea (b) Alveoli (C ) Respiratory bronchioles (d) Larynx. Describe in brief the role of lungs in the exchange of gases.

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 group constitute the right pathway of gases in the respiratory system ? A. Nostrils to Nasal cavity to Larynx to Pharynx to Bronchus to Trachea to Bronchioles to Alveolus to Blood B.Nostrils to Nasal cavity to Pharynx to Larynx to Trachea to Bronchus to Bronchioles to Alveolus to Blood

Study the diagram of human respiratory system and answer the given question. Which of these statements is incorrect regarding human lungs?

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

Which of the following comprises the lungs? a. Tracheae, b. 1^(@)"bronchi, c. "2^(@)" bronchi, d. "3^(@) bronchi, e. initial bronchioles, f. terminal bronchioles, g. duct of alveoli, h. alveoli
