Chapter 17: Digestive and Urinary Systems

The Digestive System

The most vital task that the digestive system must perform is to digest the food that you eat and make sure that the nutrients get to your cells. However, the digestive system has three main jobs: digestion, absorption, and elimination.

Digestions is the physical and chemical breakdown of foods for the use of your body's cells.

Absorption is when the digested food is transfered from the digestive tract into the cardiovascular system.

Elimination when the digested food becomes wastes it must be exerted.

The digestive system has many structures: starting from the teeth ending in the large intestine.

The process starts from the teeth where food broken down into smaller pieces.

It then travels down the esophagus to the stomach to be mixed with digestive juices where the food then travels to the small intestine half digested.

It is in the small intestine where it is determined where the food goes. The nutrients go into the bloodstream while the wastes are excerted from the body.

The Urinary System

The main objective of the urinary system is to filter the wastes from the blood and get rid of extra fluids from the body. The main organs of the urinary system are the kidneys, which act as filters and control what is excreted and how much of it.

As this process goes on, the kidneys adjust the mount of water, salts, and other substances so that too much and too little is not excreted. The fluid then goes down the ureters, which connect the kidneys to the bladder where the wastes are then excreted.

Taking care of your urinary system is just as important as taking care of any other system. To avoid problems such as Nephritis, kidney stones, and Uremia, you should do the following:

Drink at least eight 8-ounce glasses of water to always make sure that your kidneys are filtering wastes.

Eat a well-balanced diet and avoid salty foods, where salt can clog up in the kidneys and damage them.

Personal hygiene is very important to prevent the reproduction of bacteria.
