The

Digestive System

• Digestion begins in the mouth, when you chew and swallow, and is completed in the small intestine.

• The esophagus connects the throat above with the stomach below.

• The stomach stores the swallowed food and liquid, mixes the food, liquid, and digestive juices, and empties the contents slowly in to the small intestine.

• The liver turns nutrients into forms the body can use.

• Bile is a substance that helps your body digest and absorb fats. It is produced in the liver and stored in the gall bladder until needed.

• The pancreas produces pancreatic juice that contains enzymes the help break down carbohydrates, proteins, and fat.

• The small intestine produces intestinal juice to further break down food and absorption takes

place.

When you eat foods – such as bread, meat, and vegetables – they are not in a form that the body can use as nourishment.

Food and drink must be changed into smaller molecules of nutrients before they can be absorbed into the blood and carried to cells throughout the body.

Follow link to site and ask for volunteers to input their data.

BMI Calculator» BMR Formula

http://www.bmi-calculator.net/bmr-calculator/bmr-formula.php

The BMR calculator allows you to calculate your Basal Metabolic Rate (BMR) as well as other information relating to the calories you burn a day. To use the calculator, simply input details about yourself such as you age, gender, weight and height. The calculator will then calculate an estimate of your BMR and adjust you BMR by various factors to allow you to see an estimate of the calories you burn a day based on your level of activity.

Automatic processes include breathing, digesting food, and creating new cells.

Physical activities include work and exercise.

The more active you are the more energy you use.
