A flatworm expels solid waste through the structure known as mouth.
Flatworms only have one digestive opening, meaning that their mouth also serves as their anus - there is a single opening through which they eat and expel unnecessary materials. 
Flatworms don't have a cloaca and vescile, and pores are too tiny to expel solid waste through them.

Plato Answer

Explanation:

Embryonic stem cells are plentiful, and they can create every cell in the human body. Researchers can use these cells to create tissues. They can possibly grow new organs in a lab to treat diseased organs. Adult stem cells are rarer in the human body, and they’re limited in the types of cells they can make.

An embryo can’t grow without its stem cells, so people have ethical concerns about their use. Adults can provide consent to donate their stem cells, so there are fewer ethical issues regarding the use of adult stem cells.
