Frog Digestive System & Liver Functions — NEET Biology
📚 Practice ConceptDraw a neat diagram of digestive system of frog. 2. Mention the functions of the liver in frog.
Match the following frog organs with their primary functions as described in the NCERT text: Column I (Organs) Kidneys Hind limbs Liver Heart Pancreas Vocal sacs Column II (Primary Function) i. Bile production ii. Filtering nitrogenous waste iii. Pumping blood iv. Swimming, walking, leaping, burrowing v. Sound production in males vi. Produces pancreatic juice containing digestive enzymes
View solution & NCERT explanation
Correct answer: A — Kidneys-ii, Hind limbs-iv, Liver-i, Heart-iii, Pancreas-vi, Vocal sacs-v
This question requires matching specific organs of the frog with their functions described in the NCERT text. - **Kidneys**: The excretory system eliminates nitrogenous wastes, and kidneys are responsible for filtering these wastes from the blood. (NCERT: 'elimination of nitrogenous wastes is carried out by a well developed excretory system... Excretory wastes are carried by blood into the kidney where it is separated and excreted.') So, Kidneys-ii. - **Hind limbs**: The hind limbs help in swimming, walking, leaping, and burrowing. (NCERT: 'The forelimbs and hind limbs help in swimming, walking, leaping and burrowing.') So, Hind limbs-iv. - **Liver**: The liver secretes bile. (NCERT: 'Liver secretes bile that is stored in the gall bladder.') So, Liver-i. - **Heart**: The heart is a muscular structure whose pumping action achieves blood circulation. (NCERT: 'The circulation of blood is achieved by the pumping action of the muscular heart.') So, Heart-iii. - **Pancreas**: Pancreas is a digestive gland that produces pancreatic juice containing digestive enzymes. (NCERT: 'Pancreas, a digestive gland produces pancreatic juice containing digestive enzymes.') So, Pancreas-vi. - **Vocal sacs**: Male frogs can be distinguished by the presence of sound producing vocal sacs. (NCERT: 'Male frogs can be distinguished by the presence of sound producing vocal sacs.') So, Vocal sacs-v. Comparing these matches with the given options, option A is the correct one.
