Approximately 90% of these fluids are reabsorbed by the intestine, principally in the small intestine by the jejunum, which has the largest surface area. The piece of jejunum was flushed with sterile saline, then further divided into 2 cm lengths. A 6 cm piece of jejunum was cut 3 cm from the end of the duodenum. The adults were located in the duodenum and jejunum. Lengths of intestine approximately 10 cm long were taken from each of the duodenum, jejunum and ileum and processed for histology. In the more posterior regions of the intestine the villi were slightly broader and were not as tall as those of the jejunum. The jejunum was the most heavily parasitized region. Villus length and crypt depth were measured in the ileum, jejunum and duodenum and recorded for all animals. The duodenum precedes the jejunum and ileum and is the shortest part of the small intestine, where most chemical digestion takes place.
