Organs first to be injured in air blast: NEET 13
**Core Concept**
The effects of an air blast on the human body are due to the rapid transfer of energy from the blast wave to the surrounding environment. This can cause damage to internal organs through the pressure wave generated by the blast, leading to a condition known as barotrauma.
**Why the Correct Answer is Right**
The organs most susceptible to injury from an air blast are those that are not well-protected by the rib cage or skull. The lungs, heart, and gastrointestinal tract are particularly vulnerable due to their exposed location within the thoracic and abdominal cavities. The blast wave causes a rapid increase in pressure, leading to overdistension of the alveoli in the lungs and damage to the capillaries, resulting in hemorrhage and edema.
**Why Each Wrong Option is Incorrect**
**Option A:** This option is incorrect because the brain is well-protected by the skull and is less likely to be injured by an air blast.
**Option B:** This option is incorrect because the liver is protected by the rib cage and is not typically the first organ to be injured in an air blast.
**Option C:** This option is incorrect because the kidneys are also protected by the rib cage and are not as susceptible to injury from an air blast.
**Clinical Pearl / High-Yield Fact**
In the event of a blast injury, it is essential to prioritize the evaluation and management of patients with respiratory and cardiovascular compromise. Patients may present with symptoms such as coughing, shortness of breath, and chest pain, and may require immediate medical attention to prevent further complications.
**Correct Answer:** A. Lungs
