Question

Lungs are enclosed in

• A. Perichondrium
• B. Periosteum
• C. Pleural membrane
• D. Pericardium

Answer 1

The correct option is C

Pleural membrane

The correct answer is C :

Explanation of correct option:

1. The pleural cavity and its related pleurae support the lungs' ideal operation when breathing. Pleural fluid, which serves as a lubricant and enables the pleurae to readily slide against one another during breathing motions, is also present in the pleural cavity.
2. The pleura is a serous membrane that forms a two-layered membrane structure by folding back on itself. A little quantity of pleural fluid is present in the narrow gap, which is called the pleural cavity (a few milliliters in a normal human). The chest wall is joined to the outer pleura

Explanation of incorrect option:

Option A

1. The perichondrium is made up of an inner chondrogenic layer and an outside fibrous layer, both of which include fibroblasts.
2. The perichondrium's primary jobs include defending bones from harm and injury, supplying blood to the cartilage, and promoting cartilage formation.

Option B

1. It gives them the blood they require and aids in their growth and healing.
2. The periosteum is what will mend and develop your bone as you recover if you fracture or hurt a bone.
3. Periosteum refers to a thin sheath of connective tissue that helps in the growth and development of bones as well as the blood flow to the bones.

Option D

1. The pericardium serves as a lubricant to lessen friction between the heart and the surrounding tissues as well as mechanical protection for the heart and large veins.
2. Pericardium encloses the heart and helps the heart to be stable, protecting the heart from the lungs.

Final answer: Lungs are enclosed in a pleural membrane
