• C. Buccal cavity → Mouth → Pharynx → Stomach → Oesophagus → Duodenum → Small Intestine → Large Intestine → Rectum →→ Anus
• D. Mouth →→ Buccal cavity → Oesophagus → Pharynx → Stomach → Duodenum → Small Intestine → Large Intestine → Rectum → Anus

Answer 1

The Correct Option is A

To solve the problem, we need to identify the correct sequence of organs in the human digestive system.

1. Digestive System Overview:
The human digestive system is a sequence of organs through which food passes, is broken down, and absorbed. The correct flow of food through the digestive system is as follows:

• Mouth
• Buccal cavity
• Pharynx
• Esophagus (Oesophagus)
• Stomach
• Duodenum (part of the small intestine)
• Small intestine
• Large intestine
• Rectum
• Anus

2. Correct Flow Chart:
Looking at the options, the correct sequence of the human digestive system is:
Mouth → Buccal cavity → Pharynx → Oesophagus → Stomach → Duodenum → Small Intestine → Large Intestine → Rectum → Anus

Final Answer:
The correct flow chart is Option A.
