Task 1: Label the Digestive System Parts

The image shows a diagram of the human digestive system with labels provided in a table. We need to match the parts of the digestive system to their corresponding positions in the diagram.

#### Labels Provided:
- Small intestine
- Large intestine
- Mouth
- Oesophagus (also known as Esophagus)
- Stomach
- Anus
- Liver
- Pancreas

#### Diagram Analysis:
1. Mouth: Located at the top, where food enters.
2. Oesophagus: The tube connecting the mouth to the stomach.
3. Stomach: A large organ located below the oesophagus.
4. Liver: A large organ located above the stomach and small intestine.
5. Pancreas: Located near the liver and connects to the small intestine.
6. Small intestine: A long, coiled tube that absorbs nutrients.
7. Large intestine: A shorter, wider tube that absorbs water and forms waste.
8. Anus: The opening at the end of the digestive tract where waste is expelled.

#### Correct Labels for the Diagram:
- Top left: Mouth
- Middle left: Oesophagus
- Bottom left: Liver
- Center: Stomach
- Right side (top): Pancreas
- Right side (middle): Small intestine
- Right side (bottom): Large intestine
- Bottom right: Anus

Task 2: Complete the Sentences

We need to fill in the blanks using the words related to the digestive system.

#### Sentences:
a) The ________ is a long tube that pushes the food into the stomach.
b) The ________ is where the digestive process starts.
c) The ________ is like a mixer and it breaks food down into very small pieces.
d) The ________ produce juices that help to transform food into nutrients in the small intestine.
e) The ________ separates the nutrients from the waste.

#### Answers:
a) Oesophagus
- The oesophagus is a muscular tube that uses peristaltic movements to push food from the mouth to the stomach.

b) Mouth
- The digestive process begins in the mouth, where mechanical digestion (chewing) and chemical digestion (saliva enzymes) start.

c) Stomach
- The stomach mixes food with gastric juices and churns it into a semi-liquid form called chyme.

d) Liver and Pancreas
- The liver produces bile, which helps break down fats, and the pancreas produces digestive enzymes that help break down carbohydrates, proteins, and fats in the small intestine.

e) Small intestine
- The small intestine is responsible for absorbing nutrients from the digested food into the bloodstream.
