Plug your nose, then push a little. Flush and dont look back.
1, they eat and expel waste from the same opening.
Flatworms expel solid waste through a structure called the pharynx, which is a muscular tube that can extend out of their bodies. They use this pharynx to ingest food and also to expel undigested material. Additionally, flatworms possess a network of excretory canals that help in the removal of waste products, primarily through specialized cells called flame cells. These adaptations allow them to efficiently manage waste despite their simple body plan.
Waste can be categorized into several types, including solid waste, liquid waste, and gaseous waste. Plants primarily remove waste through processes like transpiration, where excess water and some metabolic byproducts are released into the atmosphere. Humans eliminate waste through various systems, including urinary and digestive systems, which expel solid and liquid waste. Flatworms, being simpler organisms, excrete waste through structures called flame cells that filter and expel waste products from their bodies.
Vertebrates have the same waste-disposal problems as invertebrates. They must deal with the very toxic ammonia their bodies produce, and most vertebrates must expel wastes while conserving water.
The structures that enable planarians to expel liquid waste are normally pores. The pores are found on the dorsal surface of the planarians.
I hope so...

They Expel Waste
Dogs expel heat in their bodies by panting.
An octopus expels waste from its body through a single opening called the anus.
They take in oxygen, and expel Carbon dioxide as a waste product.
Every living thing has to expel its waste somehow.
