1. Explain why oxygen (through a tube or mask) is provided to patients who cannot breath (ventilate). There needs to be some reference to the partial pressures involved.
2. Why is the trachea surrounded by rings of cartilage while the esophagus is not?

Oxygen is supplied to patients who cannot properly ventilate in order to increase the amount of oxygen in the body tissues. Within the tissues of the body, the partial pressure of oxygen can be increased when oxygen therapy is supplied compared to the partial pressure of oxygen than can diffuse into body tissue's from breathing in normal atmospheric conditions.

A common reason that oxygen therapy is used at home is to help people with chronic obstructive pulmonary disease (COPD). Often ...
