Correct Answer: Option A
Explanation:
The correct answer is:
A. oral cavity - oesophagus - stomach - ileum - rectum
This option gives the correct sequence in the digestive system of a mammal for the movement of food like bread:
1. Oral cavity – Where food is chewed and mixed with saliva.
2. Oesophagus – Transfers food to the stomach.
3. Stomach – Begins protein digestion; churns food into chyme.
4. Ileum – Part of the small intestine where most digestion and absorption of nutrients (like carbohydrates from bread) occurs.
5. Rectum – Final section of the large intestine; stores waste before elimination.
Other options mix up the order:
- B: Incorrect – oesophagus comes before stomach, not after.
- C: Missing key digestive parts.
- D & E: Wrong order (ileum should come after stomach and duodenum).
