Explanation / Answer

Answer-1 (c) Fossae
Explanation-
Nasal fossa are the two cavaties seperated by a vertical plane.

Answer-2 (c) The arytenoid cartilages

Explanation-
These are pair of pyramid-shaped pieces of cartilage found in the larynx i.e. the voice box. These are essential for the production of vocal sound.

Answer-3 (a) respiratory bronchioles
Explanation-
These are the final divisions within the bronchioles. They deliver air to the exchange surfaces of the lungs.

Answer-4 (e) medulla oblongata
Explanation-
Intrinsic focal tumor of the medulla oblongata leads to C02 retention, with associated respiratory arrest and hypoxia.

Answer-5 (e) vital capacity
Explanation-
The vital capacity is the greatest volume of air that can be expelled out from the lungs.

Answer-6 (c) inflation reflex
Explanation-
The Hering-Breuer inflation reflex, is a reflex which is triggered to prevent the over-inflation of the lungs.

Answer-8 (a) ischemic
Explanation-
Ischemic hypoxia is reduced blood oxygen that results by inadequate blood flow to the brain.
