Explanation / Answer

64. ANS: C. Cricoid Cartilage

The ring of the hyaline cartilage that forms a base of larynx is cricoid cartilage.

65. ANS: B. Has C shaped cartilage that forms its anterior and lateral sides.

The trachea carries air between larynx and bronchi. It has C shaped cartilage hynoid bone in its wall.

66. ANS: B. Secondary Bronchus.

Left bronchus bifurcates into two secondary or lobar bronchi for air delivering to two lobes of the left lungs called superior & inferior lobe. Again the secondary bronchi divide into tertiary bronchi.

67. ANS: A. Alveoli

Alveoli are the place where oxygen and carbon dioxide exchanges from lungs to blood.

68. ANS: C. Mucosa, Sub mucosa, Muscularis, Serosa.

The sequence of the digestive tract wall lumen is Mucosa, Sub mucosa, Muscularis and Serosa.

69. ANS: B. Mass movements.
