6.Define compliance and resistance of the lungs.?

7.Name the four layers of the digestive tract from superficial to deep.?

8.The oral cavity is lined by which type of epithelium?

please type it

Answer 1

1.C shaped trachealcartilages supports the anterior and lateral sides of trachea to protect and maintaintain the airway open.

2.The alveoli would collapse if alveoli surfactant is not produced because of the surface tension in the layer of water thet moistens the surface of the alveoli.

3.Diaphragm and external intercostal muscles are the primary inspiratory muscles.

4.Respiratory rate is the number of breaths per minute and is controlled by respiratory center.

5.Carbon dioxide is transported in the bloodstream as bicarbonate ions,bound to hemoglobin and dissolved in plasma.

6.Lung compliance is the measurement of ability of lungs to stretch and expand.Lung resistance is the opposition to flow caused by frictional forces.

7.Mucosa,submucosa,muscularis externa and serosaare the four layers of digestive tract.

8.The oral cavity is lined by stratified squamous epithelium
