INTESTINO

DELGADO

State the organs present in the digestive system. Describe the role and function of the digestive organs. Explain how villi support food absorption. LEARNING POINTS

This is the start of the digestive system. The teeth mechanically grind down the food. The saliva, made in salivary glands, chemically digests the food using enzymes.

MOUTH

The liver releases a chemical called bile into the intestines via the gall bladder. Bile breaks down lipids (fats and oils) in food.

LIVER

The stomach is a muscular bag which contains acid. It mixes food and drink with the acid.

STOMACH

This is where bile is stored and concentrated before it is released into the small intestine. Bile is produced in the liver to break down lipids.

GALL BLADDER

Foods such as carbohydrates, proteins and lipids are digested here. Nutrients from these foods are absorbed into the blood.

SMALL

INTESTINE

The large intestine contains food which cannot be broken down further, usually fibre. Water is absorbed into the blood.

LARGE

INTESTINE

State the organs present in the digestive system. Describe the role and function of the digestive organs. Explain how villi support food absorption. LEARNING POINTS
