Digestion
Disaccharide
A double sugar, consisting of two monosaccharides.
Enzymes are
A group of chemicals in the body helps to control a wide variety of chemical reactions including the breakdown into simpiler substances.
Saliva contains a chemical substance that breaks down some of the starches in food into sugars in the mouth
Amylase
Solid wastes exit the body through this opening....
Anus
The three functions of a digestion process are...
Breaks down food, absorption and eliminates waste.
Formula for glucose...
C6 H12 O6
What is chemical digestion?
CD = chemical process, salivary glands, (Amylase)
Pepsin
Chemical digestion is aided by the enzyme contained in Gastric juice
The process if breaking down food into small nutrient molecules is called _____________.
Digestion
protein that speeds up a chemical reactions in the body is an __________. Chemical digestion accomplished by these proteins.
Enzyme
After you swallow, smooth muscles force food into the tube that transports food from the mouth to the stomach
Esophagus
Digestive Process...
Food enters the mouth, moves through the esophagus and into the stomach.
How does fiber aid digestion?
Helps food move along, provides the bulk needed
The body's largest and heaviest organ that produces bile aids in digestion.
Liver
What is mechanical digestion?
MD = physical movement, teeth
Small intestine
Most digestion takes place in the organ that is more than 6 meters log and only 2.5 cm in diameter.
Pancreas
The soft, triangular organ that produces insulin that is important in controlling the body's use of sugar.
when you swallow food, a flap of tissue called the __________________ seals off your windpipe.

peristalsis
Monosaccharides are
simple sugars
Is directly attached to the stomach
small intestine
Most absorption of nutrients occurs here
small intestine
Most chemical digestion occurs here
small intestine
Receives bile and enzymes from other organs.
small intestine
is lined with villi
small intestine
Most mechanical processing of food occurs in the _____.
stomach
The process of ______________ involves the movement of nutrients through the wall of your digestive system into your blood.
absorption
Breaks up fat molecules
bile
Produces enzymes that flow into the small intestine
Pancreases
Structure in which waste material is compressed into solid form
Recutm
Food undergoes mechanical and chemical digestion in the J-shaped organ that releases a fluid called gastric guice.
Stomach
Tiny singer-shaped structures in which absorption occurs...
Villus
Peristalsis
Waves of rhythmic muscular contractions push food through the digestive system.
