nhung mao

Các nhung mao trong ruột non giúp hấp thụ chất dinh dưỡng.

Definition

Noun (Biology, Anatomy):
- Villus (plural: villi): A tiny, hair-like projection, especially one found on the surface of a mucous membrane. The term most commonly refers to the intestinal villi, which are microscopic finger-like projections lining the small intestine that increase its surface area for the absorption of nutrients.
- Cilia (singular: cilium): Microscopic, hair-like structures that extend from the surface of many animal cells. They often function in movement, such as moving fluid or particles over a cell's surface.

Usage Examples

Noun:
- Các nhung mao trong ruột non giúp hấp thụ chất dinh dưỡng. (The villi in the small intestine help absorb nutrients.)
- Một số tế bào hô hấp có nhung mao để đẩy chất nhầy ra ngoài. (Some respiratory cells have cilia to move mucus outward.)

Advanced Usage

The term is highly specialized and used almost exclusively in scientific, medical, and biological contexts.
"Nhung mao ruột": intestinal villi.
- Tổn thương nhung mao ruột có thể dẫn đến kém hấp thu. (Damage to the intestinal villi can lead to malabsorption.)
"Nhung mao lông chuyển": motile cilia (specifically referring to cilia that beat rhythmically).

Notes on Meaning

The core meaning of "nhung mao" is a microscopic, hair-like projection. The specific English translation depends on the biological context:
- Use "villus/villi" when referring to anatomical structures for absorption, especially in the digestive system.
- Use "cilium/cilia" when referring to cellular organelles involved in movement or sensory functions.
It is not used in everyday conversation.
