How do mammals excrete there waste products?

Answer 1

Okay, the answer i got for this question was that mammals excrete in two ways. The first was in during the digestive system, It simply means that the waste goes through the body and out the anus. The other way is that they go through chemical waste. This means whenever a mammal breathes for example, you breathe in air but you must breathe out the chemical carbon dioxide from the body.

Answer 2

There's three main types of wastes that mammals excrete: 1) Undigested food, which is defecated from the rectum, 2) metabolic wastes which are excreted in the urine, and 3) carbon dioxide, which is exhaled. For the undigested food, there are some molecules, such as cellulose, that mammals just don't have the digestive enzymes to break down. If mammals didn't get rid of it, it would simply build up in the colon, causing uncomfortable pressure on the colon and potentially rupturing the colon, releasing wastes and bacteria into the body. For metabolic wastes, if left to themselves nitrogenous wastes will denature (unfold) proteins eventually cause major neurological damage, sending the animal into a coma. Carbon dioxide, when it combines with water, becomes carbonic acid, which makes the blood acidic, potentially damaging proteins and reducing the effectiveness of many of the body's enzymes.

Answer 3

They urinate and defecate.
