Zoology - Breathing and Exchange of Gases Question with Solution | TestHub
How many from the given below is/are the correct match?
I. Asthma: difficulty in breathing due to inflammation of bronchi and bronchioles.
II. Carboxy-haemoglobin: form when carbon dioxide binds to hemoglobin
III. Carbonic anhydrase: this enzyme concentration is high in blood plasma
IV. Pneumotaxis center: it controls respiration and is present in the medulla
Options:
Answer:
Solution:
Asthma is the result of chronic inflammation of the airways which subsequently results in increased contractibility of the surrounding smooth muscles leading to narrowing of the airway and the classic symptoms of wheezing. When carbon monoxide binds to hemoglobin the resultant compound is called carboxy-hemoglobin. The concentration of carbonic anhydrase enzyme remains high inside RBCthan blood plasma. The pneumotaxic center is situated in the upper part of the pons towards the dorsal side. It is connected to all the neurons of the dorsal respiratory group and only the inspiratory neurons of the ventral respiratory group.
