Explanation / Answer

1.

Larynx is commonly called voice box, which is located in the neck of amphibians, reptiles, and mammals. It is involved in breathing, sound protection, and protects the trachea. Larynx is directly attached to hyoid bone.

2.

Laryngitis is the condition in which the individual will be unable to speak due to inflammation in and around area of larynx. Thus, the structure that is inflamed in laryngitis is larynx.

3.

The type II or great alveolar cells covers only 3% of alveolar surface, while 97% is covered by type I cells. These are the secretory cells that secrete pulmonary surfactants.

4.

The cluster of neurons in the medulla oblongata that has most responsibility for producing the breathing rhythm is the dorsal respiratory group.

9.

There are four types of cells in the stomach, which includes parietal cells, gastric chief cells, mucous neck and pit cells, and G cells. Gastric chief cells produce gastric lipase and pepsinogen.
