Waste Disposal

Disposal of the waste


  • There are two systems that get rid of waste.
  • The two systems are the digestive system and chemical waste.

Digestive System 

  • First of all, lets explain what the digestive system is.
  • The digestive system is a group of organs working together to convert food into energy and basic nutrients to feed the entire body.

Why is it even important for the mammal?

  • As we know, the digestive system break down food into nutrients, which the body uses for energy, growth and cell repair. 
  • The body breaks down nutrients from food and drink into carbohydrates, protein, fats, and vitamins. 

Process?

  • Process starts in the mouth. Food is partly broken down due to chewing and by salivary enzymes.
  • On the way to the stomach- the esophagus. After food is chewed up and swallowed, it enters the esophagus. An esophagus is a long tube running down from the throat to the stomach.
  • In the stomach. The food enters the stomach and is partly digested and mixed with stomach acids called chyme. 
  • In the small intestine. pancreatic enzymes, and other digestive enzymes produced by the inner wall of the small intestine help in the breakdown of food.
  • In the large intestine. In it, some of the water and electrolytes are removed from the food. 
  • End of the process. Solid waste is then stored in the rectum until it is released via the anus.

Chemical Waste

  • An example of chemical waste is when a mammal breathes out, the chemical carbon dioxide is released from the body.

FUN FACT OF THE POST!
  • The small intestine contains so many folds that its total surface area is about 2,700 square feet, enough to cover a tennis court!
