What are lymphatic capillaries also known as?

Lymphatic capillaries are commonly known as lacteals, which is a specific term referring to the lymphatic vessels located in the villi of the small intestine. Their primary function is to absorb dietary fats and transport them into the lymphatic system, differentiating them from other types of lymphatic vessels. The term "lacteal" is derived from the Latin word "lacteus," meaning milky, due to the appearance of the lymph when it is laden with emulsified fats.

This identification is crucial for understanding the role of the lymphatic system in nutrient absorption and the body's overall fluid balance. Lacteals play a significant role in the digestive process, collecting the chyle, which is the milky bodily fluid containing fat droplets.

The other options represent different structures within the circulatory system or lymphatic system but are not specific to the capillaries themselves. Chyle vessels refer to the transport route for chyle processed by the lacteals, thoracic ducts are the large lymphatic vessel that drains lymph from the body, and veins refer to blood-carrying vessels distinct from lymphatic vessels. Thus, categorizing lymphatic capillaries as lacteals highlights their specialized function in fat absorption and their
