crypts

Crypts are small, tube-like structures found in tissues such as the lining of the intestines or the nasal cavity. They serve as sites where stem cells reside and divide, replenishing the lining cells that wear out or get damaged. This ongoing renewal process is essential for maintaining tissue health and function. In the intestines, crypts help produce new cells for the lining, aiding digestion and absorption. In other tissues, they may have roles in immune defense or tissue repair. Overall, crypts are crucial for tissue maintenance and regeneration.
