I don’t know you should ask your teacher
The correct answer is Thoracic Cavity
Explanation:
In the human body, the thoracic cavity is located above the abdomen and below the neck. This cavity includes vital organs such as the lungs and the heart. Moreover, this cavity is surrounded by bones such as the ribs. Besides this, while driving the thoracic cavity is expected to be in front of the steering wheel because the steering wheel is always in front of the chest of the driver. Due to this, if William's body slammed into the steering wheel during the accident is likely this cavity was the one most affected due to its position.
Blood PC02 may be measured by using direct spectrophotometer
Explanation:
Blood gas analysis or arterial blood gas (ABG) test is done to determine blood pH and the amount of oxygen and carbon dioxide dissolved in arterial blood.
Blood PCO2 is the partial pressure of carbon dioxide dissolved in the arterial blood.
ABG or oximetry test is done by using direct spectrophotometry in a spectrophotometer and gas analysis is done by calorimetric methods. Spectrophotmetry is highly used in Medicine to perform quantitative analysis of blood and its composition. The spectrophotometer measures the light intensity or wavelengths absorbed by the sample solution.
Blood PCO2 reflects the degree of exchange gases in and out of the lungs. An increase in PCO2 levels indicates respiratory illnesses like obstructive lung diseases or pulmonary edema; while a decrease indicates conditions like hypoxia, pulmonary embolism, hyperventilation etc.
