Biol Digestion System

Front 1

Mechanical Digestion. Plus Example

Back 1

Mechanical digestion involves physically breaking the food into smaller pieces. Mechanical digestion begins in the mouth as the food is chewed.

Example: Food is chewed in the mouth to allow a bigger surface area to volume ratio.

Front 2

Chemical Digestion. Plus Example

Back 2

Chemical digestion involves breaking down the food into simpler nutrients that can be used by the cells. Chemical digestion begins in the mouth when food mixes with saliva.

Example: Food is mixed with saliva and broken down.

Role of Emzymes

Back 3

That means enzymes break down proteins, cellulose, starches and other foodstuffs. This makes it possible for the intestines to absorb nutrients. Enzymes begin the digestive process in the mouth, as they're secreted by salivary glands. They work to break down starch into sugars.

Front 4

Role of amylase

Back 4

breaks down carbohydrates, starches, and sugars which are prevalent in potatoes, fruits, vegetables, and many snack foods

Front 5

Role of protease

Back 5

breaks down proteins found in meats, nuts, eggs, and cheese

Front 6

Role of lipase

Back 6

breaks down fats found in most dairy products, nuts, oils, and meat

Front 7

Function of Saliva

Back 7

Produced in salivary glands, saliva is 98% water, but it contains many important substances, including electrolytes, mucus, antibacterial compounds and various enzymes. The digestive functions of saliva include moistening food, and helping to create a food bolus, so it can be swallowed easily.

Front 8

Role of Ingestion

Back 8

All Animals are heterotrophs need to consume or ingest food. Ingestion of food is to go through the mouth of an animal yet some species ingestion is through another means.

In simple: Ingestion is food entering the mouth.

Role of Digestion

Back 9

The role of digestion is to break down food and absorb the nutrients in the food that you are consuming.
