Which of the following statements regarding the digestive system of Ra...
The correct answer is Option A - A, C, D and E only
The liver of the frog is a large, two-lobed (bilobed) organ that produces bile; bile aids the digestion of fats by emulsification, making fat droplets accessible to lipase action.
The stomach carries out initial mechanical and protein digestion (pepsin action), but digestion is not completed there; most chemical digestion and absorption occur in the small intestine, so the statement that digestion is completed in the stomach is incorrect.
The pancreas is present in frog and secretes digestive enzymes (pancreatic enzymes) into the duodenum, contributing to the breakdown of carbohydrates, proteins and fats.
The intestine is differentiated into the duodenum, ileum (parts of the small intestine) and the rectum (part of the large intestine), with the duodenum receiving bile and pancreatic secretions for further digestion.
The cloaca is a common chamber into which the digestive, excretory and reproductive ducts open, serving as the single external opening for these systems.
Therefore, statements A, C, D and E are correct, which corresponds to Option A.
Topic in NCERT: Digestive system
Line in NCERT: "digestion of food takes place by the action of hcl and gastric juices secreted from the walls of the stomach."
"final digestion takes place in the intestine."
"the main digestive glands are liver and pancreas."
"the alimentary canal consists of oesophagous, stomach, intestine and rectum, which open into the cloaca."
"the cloaca is a small, median chamber that is used to pass faecal matter, urine and sperms to the exterior."

Which of the following statements regarding the digestive system of Ra...
Overview of Rana tigrina Digestive System
Rana tigrina, commonly known as the frog, has a unique digestive system adapted for its carnivorous diet. Let's analyze the statements regarding its digestive system:
Statement A: Liver Functionality
- The liver is indeed bilobed in frogs.
- It plays a crucial role in the digestion of fats by producing bile, which aids in fat emulsification.
Statement B: Digestion Completion
- Digestion is not completed in the stomach; rather, the stomach primarily serves as a site for the initial breakdown of food.
- Further digestion and absorption occur in the intestine, making this statement incorrect.
Statement C: Presence of Pancreas
- Frogs have a pancreas that secretes digestive enzymes essential for breaking down proteins, carbohydrates, and fats.
- This statement is correct.
Statement D: Intestinal Differentiation
- The intestine of frogs is not distinctly divided into duodenum, ileum, and rectum.
- It generally has a more simplified structure compared to mammals, making this statement incorrect.
Statement E: Cloaca Function
- The cloaca serves as a common chamber for the digestive, excretory, and reproductive systems in frogs.
- This statement is correct.
Conclusion
Based on the analysis:
- The correct statements are A, C, and E.
- Therefore, the right option is A: "A, C, D and E only," as it correctly identifies the operational aspects of the frog's digestive system, including the liver's role, the presence of the pancreas, and the function of the cloaca.
This explanation clarifies the reasoning behind the correct answer about the digestive system of Rana tigrina.
