Answer 3

When we eat/drink/sniff something, most of it ends up in our blood. What does not end up in our body continues to move down the digestive system until it is passed. This is part A of excretion and is removed via the anus. The substances that enter the blood go to several places 1.Some of it goes into storage sites. 2.Some goes to organs that can turn it into substances useful for the body 3.Some goes to organs where it is detoxified, and the sent for excretion. 4.Some goes directly to where it is needed, and side products are sent back to the blood 5.The rest remains unused in the blood Eventually the detoxified (3) substances, the sideproducts (4), and the unused components (5) are also excreted. This is part B of excretion. So the answer is that Part A and Part B are excreted products, but the rest I wrote is the process of excretion. Good luck! Hope this helps (try and ignore the mean responses-LOL) Art OOPS, forgot the second part.... Excretion is important to feed the body, and to maintain body homeostasis to keep the body healthy and free of toxins.
