Lymph capillaries

Lymph Capillaries

Lymph capillaries (pronunciation: /ˈlimf ˌkapəˈlerēs/) are the smallest vessels in the lymphatic system, and they play a crucial role in the body's immune response.

Etymology

The term "lymph capillaries" is derived from the Latin word "lympha," which means "water," and the Latin word "capillaris," which means "hair-like." This is a reference to the small, thin structure of these vessels.

Function

Lymph capillaries are responsible for the absorption of interstitial fluid and its return to the bloodstream. They also absorb lipids from the digestive system and transport them to the bloodstream.

Structure

Lymph capillaries are thin-walled vessels composed of a single layer of endothelial cells. They are slightly larger in diameter than blood capillaries and have a unique structure that allows them to absorb larger molecules and cells.
