**Question:**

Which of the following is not true about the functions of lymphatic capillaries?

A) Absorb the excess protein-containing interstitial fluid  
B) Return interstitial fluid to the bloodstream  
C) Deliver leaked red blood cells to capillaries  
D) Have minivalves and protein filaments  
E) They can uptake pathogens and cancer cells  

**Explanation:**

Lymphatic capillaries play a crucial role in maintaining fluid balance in the body by collecting excess interstitial fluid, including proteins, and returning it to the bloodstream. They are equipped with minivalves and protein filaments to facilitate this fluid movement and to ensure unidirectional flow. Additionally, they can uptake pathogens and cancer cells, aiding in immune surveillance. However, lymphatic capillaries do not deliver red blood cells to capillaries; this function pertains to blood capillaries.
