Question

How do the digestive and excretory systems work together to help the body get what it needs and get rid of what it doesn't need?​

Answer 1

Simple, One Part Digests and Then One part Excretes.

Step-by-step explanation:

When You Eat Something The teeth break down the food first and then the tongue helps to get saliva on the food, which rolls it into a ball, then after that it then goes down the foodtube, and into the stomach, the stomach breaks down the food further, and then after that the liver, pancreas, and gallblader releases its juices and digests it even further, it then goes into the intestines where nutrients gets absorbed, water gets absorbed, its sent to the urinary system and then once the rectum is full of poop, nerves send the brain a signal and then you sense that there is poop, you poop, and flush the toilet. :)
