This functional tissue unit (FTU) illustration includes cell types related to the acinus FTU in the ASCT+B Table Pancreas v1.1. Cell types and measurements were referenced from (Morgan, Schaeffer, and Longnecker 1986). Uberon describes this FTU as follows: "The secretory units of the exocrine pancreas, where fluid containing digestive enzymes is produced; consists of a group of secretory cells surrounding a luminal space that connects to the pancreatic duct."
