The correct Answer is:
To answer the question, "If thorax is injured and pleura damaged, the air enters the pleural cavity and the lungs are collapsed. This condition is known as," we will analyze the options provided and determine the correct medical term for this condition. ### Step-by-Step Solution: 1. **Understanding the Scenario**: The question describes a situation where there is an injury to the thorax and damage to the pleura, leading to air entering the pleural cavity and causing the lungs to collapse. 2. **Identifying the Options**: The options provided are: - A) Hyponia - B) Orthopnea - C) Dyspnea - D) Pneumothorax 3. **Analyzing Each Option**: - **A) Hyponia**: This term refers to a sleep disorder and is not related to lung conditions. Therefore, this option is incorrect. - **B) Orthopnea**: This condition describes difficulty in breathing when lying down. It is not related to the collapse of lungs due to air in the pleural cavity. Thus, this option is also incorrect. - **C) Dyspnea**: This term refers to difficulty in breathing, often associated with conditions like asthma. However, it does not specifically describe the condition where air enters the pleural cavity and causes lung collapse. Therefore, this option is incorrect as well. - **D) Pneumothorax**: This is the medical term for the condition where air enters the pleural space, leading to lung collapse. It occurs due to injury or rupture of lung tissue, allowing air to escape into the pleural cavity. This option accurately describes the scenario given in the question. 4. **Conclusion**: After analyzing all the options, the correct answer is **D) Pneumothorax**. ### Final Answer: The condition where air enters the pleural cavity due to thoracic injury and causes lung collapse is known as **Pneumothorax**.

Air entering the lungs ends up in tiny sacs called alveoli.From the alveoli, the oxygen diffuses into the blood.
