Ileum, the final and longest segment of the small intestine. It is specifically responsible for the absorption of vitamin B12 and the reabsorption of conjugated bile salts.
The image in HA6 is deep in the wall of the ileum and shows many crypts cut in different planes of section surrounded by a CT layer called the lamina propria. Cells in the crypt divide (HA6, arrows) and push the epithelium toward the tip of the villus in the process of cell turnover (HA6) .The mitotic cells in this part of the epithelium provide a constant supply of new cells, while other cells are being sloughed into the lumen at the tip of the villus (HA7, arrows) .A4-8: Ileum-fast green, hematoxylin & PAS. Refer to the diagram in your coursebook to begin to understand the 3-dimensional structure of the lining of the small intestine. Begin by looking at the lumen of the ileum (top, HA4).
