A comparative study of chloride, bicarbonate and water transport by terminal ileum of Canis familiaris, Oryctolagus cuniculus and Capra hircus

1. The differences in the movement of chloride, bicarbonate and water across the ileal wall has been studied in dog, rabbit and goat both in conscious and anesthetized animals. 2. The rate and direction of chloride transport rely on its intraluminal levels for the three species considered. 3. Chloride absorption by dog ileum is higher than in rabbit and goat. 4. There is a relationship between the net movement of bicarbonate and its luminal concentration for the three species studied. 5. The trend to bicarbonate secretion is lower in dog than in rabbit and goat. 6. Under the same experiment conditions, water is absorbed by the dog ileum while it is secreted by this intestinal portion in rabbit and goat.
