Exocrine acini
Pars exocrina pancreatis · Exokrinní aciny
Digestive system
Looks like
Tiny grape-like clusters of cells making up most of the pancreas.
What it does
Produce the enzymes that digest fat, protein and starch, and bicarbonate to neutralise acid.
Keeping it well
Chronic pancreatitis and cystic fibrosis destroy them; pale, oily, hard-to-flush stools with weight loss mean enzymes are lacking and can be replaced.
