In which part of the body would you find the stratum corneum?

The stratum corneum is the outermost layer of the skin, which is a critical component of the integumentary system. This layer consists of dead skin cells that provide a barrier to protect underlying tissues and prevent water loss. The cells in the stratum corneum are filled with keratin, a tough protein that helps maintain the skin's integrity and resilience against environmental damage, pathogens, and dehydration.

The other options refer to internal organs or systems that do not contain the stratum corneum. The stomach has a mucosal lining that aids in digestion, the lungs have respiratory epithelium facilitating gas exchange, and the intestines have a mucosal lining for nutrient absorption—all of which serve different functions and do not involve the structural characteristics of the skin layers. This specialization highlights the importance of the stratum corneum as a protective layer in the skin.
