MCQ Detailed View

The lungs are delicate, soft, and spongy organs that play a vital role in the respiratory system, allowing oxygen to enter the blood and carbon dioxide to be removed. Because they are very sensitive, the body has developed a strong natural protection for them called the ribcage.

The ribcage is made up of 12 pairs of ribs, the sternum (breastbone), and the thoracic vertebrae at the back. Together, they form a bony cage around the chest cavity. This structure not only protects the lungs but also shields the heart, major blood vessels, and other important organs located in the chest.

During breathing, the ribcage also helps expand and contract the chest cavity. The ribs move slightly upward and outward when we inhale, allowing the lungs to fill with air. When we exhale, the ribs return to their resting position, helping push the air out.

Let’s look at the options:

• 
  

  Option A (luvcage): This is not a biological term; therefore, it is incorrect.

  
  


• 
  

  Option B (Ribcage): This is the correct answer, as the ribcage is the protective bony cage around the lungs.

  
  


• 
  

  Option C (Both A & B): Incorrect, since only ribcage is correct.

  
  


• 
  

  Option D (None of these): Incorrect because ribcage is the right answer.

  
  

The ribcage has a dual role: protection and support in breathing. Without the ribcage, even a minor injury could severely damage the lungs or heart. This shows how important the skeletal system is in keeping the delicate organs safe.

In summary, the lungs are protected by the ribcage, which provides strength, protection, and flexibility necessary for breathing and survival.
