Question

The diagram shows the digestive system.

Where does egestion take place?

▶️ Answer/Explanation
Egestion is the process of discharging undigested food material and waste products from the body. In the provided diagram, label D points to the anus, which is the final opening of the digestive tract where this process occurs. Label A represents the mouth (ingestion), B indicates the stomach (digestion), and C identifies the small intestine (absorption). Since egestion specifically refers to the elimination of waste that was never absorbed into the blood, it concludes at the very end of the alimentary canal.
✅ Answer: (D)
Question

The diagram shows the digestive system and some of its associated organs. Which label identifies the liver?

Digestive System Diagram
▶️ Answer/Explanation
Solution

Ans: A

The liver is located in the upper right abdomen, below the diaphragm and to the right of the stomach. In the diagram, Label A correctly identifies the liver due to its:

  • Position (upper right quadrant)
  • Large, lobed structure
  • Proximity to the stomach (Label B) and gallbladder (if visible)

Why other labels are incorrect:
– B: Likely the stomach (J-shaped, below the liver).
– C: Small intestine (coiled structure, lower abdomen).
– D: Possibly the pancreas (smaller, behind the stomach).

Options Table

▶️ Answer/Explanation
Solution

Ans: B

The diagram shows key structures of the alimentary canal and associated organs. Based on anatomical knowledge:

    • 2 is the pancreas (secretes digestive enzymes).

3

    • is the

small intestine

    • (nutrient absorption).
  • 4 is the liver (produces bile).

Option B correctly matches these labels, while the other options misidentify one or more structures. Thus, the correct answer is B.
