What similaritys exist in the digestive system of frog and man?

Similarities in Digestive Systems of Frog and Man

1. Alimentary Canal: Both the frog and humans have a complete alimentary canal that consists of the following major sections: mouth, esophagus, stomach, small intestine, large intestine, and anus.

2. Mechanical Digestion: Both the frog and humans use mechanical digestion to break down food. The frog's tongue, teeth, and stomach muscles all contribute to mechanical digestion, while humans use their teeth, tongue, and esophageal muscles for the same purpose.

3. Chemical Digestion: Both the frog and humans use enzymes to chemically break down food. The frog produces enzymes in its mouth, stomach, and small intestine, while humans produce enzymes in the mouth, stomach, pancreas, and small intestine.

4. Absorption: The frog and humans both have specialized structures in their small intestines that help to absorb nutrients from digested food. In the frog, these structures are called villi, while in humans, they are called microvilli.

5. Egestion: Both the frog and humans eliminate solid waste through the anus.

Additional Similarities:

- Both the frog and humans have a liver that helps to regulate metabolism and produce bile for digestion.

- Both the frog and humans have a pancreas that produces enzymes and insulin for digestion.

- Both the frog and humans have a gallbladder that stores and releases bile for digestion.
