Respiratory drugs
| Question | Answer |
|---|---|
| What structures would a molecule of oxygen pass over or through as it travels from the environment to the alveoli? | Nostirls, nasal cavity, pharynx, larynx, trachea, bronchi, and bronchioles. |
| What are the four primary functions of the respiratory system? | Oxygen-co2 exchange, regulation of acid-base balance, body temp. regulation, and voice production. |
| Describe the function of the three basic defense mechanisms of the respiratory system | 1. Structures in the nose filter, warm, and humidify inspired air. 2.cough sneeze to remove foreign material that has entered the respiratory system. 3. mucociliary mechanism also removes foreign material from the respiratory system. Macrophages and immun |
| What are three important principles of respiratory therapeutics? | Control of secretions, control of reflexes, and maintenance of normal air flow. |
| Expectorants are indicated when what type of cough is present? | Productive |
| Mucolytics decrease the viscosity of respiratory mucus by what mechanism? | Through the breakdown of disulfide chemical bonds |

| What drug category is Theophylline? | Methylxanthine |
| What drug category is Dopram? | Respiratory stimulant |
| What is the mechanism of action of most antitussives used in vet med? | Through depression of the cough center in the brain |

| Give an example of a beta2-adrenergic agonist bronchodilator | albuterol |
| ____ are drugs that inhibit or suppress coughing | Antiitussives |
| _______is used for the relief of chronic nonproductive coughs in dogs, and for analgesia and preanesthesia in dogs and cats | butorphanol tartrate |
