A. true
b. false: rodents and rabbits should not be fasted prior to surgery because they are unable to vomit due to their esophageal physiology, unless there are other medical/scientific reasons for doing so.

The given statement is true.

Explanation:

The surgery procedure in animals differs. In case of animals such as cat or dog, they must not be feed before surgery and must be kept in fasting phase. On contrary in case of rodents and rabbits they must not fast before the surgery unless the medical condition of the animal demands so.

The reason behind feeding before surgery in case of rodent and rabbit is that, it is nutrient obtained from food and water helps in quick recovery of the animals in post operational stage and also it is a tedious process to make them eject out the digested content before surgery due to their esophageal physiology.

air enters through the nose, moves through the nasal cavity, the pharynx, the larynx, enters the trachea, moves through the bronchi andbronchioles till the alveoli.
