Digestive system of a penguin

Answer 1

The digestive system of a penguin is specially adapted to process a diet primarily consisting of fish and krill. It begins with the beak, which captures prey and leads to the esophagus, where food is temporarily stored in the crop. The stomach has two parts: the proventriculus, which secretes digestive enzymes, and the gizzard, which grinds food with the help of ingested stones. Nutrient absorption occurs in the intestines, where waste is eventually excreted through the cloaca.
