Covers the digestive system, including organs like the stomach and intestines, and the respiratory system, such as lungs and skin breathing in frogs.
Frogs have a pancreas that secretes digestive enzymes for breaking down food.
Ref: NCERT Class 11 Biology Chapter 7: Structural Organisation in Animals Frog - Anatomy - Digestive and Respiratory System
Frogs respire through their lungs on land, through their skin in water, and via buccal respiration.
Ref: NCERT Class 11 Biology Chapter 7: Structural Organisation in Animals Frog - Anatomy - Digestive and Respiratory System
During the tadpole stage, frogs use gills for respiration before developing lungs in adulthood.
Ref: NCERT Class 11 Biology Chapter 7: Structural Organisation in Animals Frog - Anatomy - Digestive and Respiratory System
The duodenum, the first part of the small intestine, receives bile and pancreatic juices for digestion.
Ref: NCERT Class 11 Biology Chapter 7: Structural Organisation in Animals Frog - Anatomy - Digestive and Respiratory System
During hibernation, frogs rely on cutaneous respiration, where oxygen is absorbed through their moist skin.
Ref: NCERT Class 11 Biology Chapter 7: Structural Organisation in Animals Frog - Anatomy - Digestive and Respiratory System
The liver secretes bile, which is stored in the gall bladder and helps in fat digestion.
Ref: NCERT Class 11 Biology Chapter 7: Structural Organisation in Animals Frog - Anatomy - Digestive and Respiratory System
The gall bladder stores bile secreted by the liver and releases it into the duodenum for digestion.
Ref: NCERT Class 11 Biology Chapter 7: Structural Organisation in Animals Frog - Anatomy - Digestive and Respiratory System
Metamorphosis in frogs occurs during the tadpole stage, where they develop limbs and lungs to transition into adult frogs.
Ref: NCERT Class 11 Biology Chapter 7: Structural Organisation in Animals Frog - Anatomy - Digestive and Respiratory System
Frogs use gills only during their larval (tadpole) stage, but as adults, they rely on lungs and skin for respiration.
Ref: NCERT Class 11 Biology Chapter 7: Structural Organisation in Animals Frog - Anatomy - Digestive and Respiratory System
Metamorphosis in frogs is primarily controlled by thyroid hormones, not general growth hormones.
Ref: NCERT Class 11 Biology Chapter 7: Structural Organisation in Animals Frog - Anatomy - Digestive and Respiratory System
Frogs use pulmonary respiration on land (lungs) and cutaneous respiration in water (skin).
Ref: NCERT Class 11 Biology Chapter 7: Structural Organisation in Animals Frog - Anatomy - Digestive and Respiratory System
Metamorphosis in frogs is primarily controlled by thyroid hormones, not the adrenal gland.
