Sažetak
The histological structure as well as the histochemical content and distribution of glycoproteins (GPs) in the digestive tract mucosa of the Atlantic bluefin tuna were studied. The digestive tract of the bluefin tuna is short in accordance with their predatory nature and consists of the oesophagus, stomach and intestine. The oesophagus is short with deep longitudinal folds. The oesophagus shows the presence of abundant secretory cells which synthesize a large quantity of neutral as well as sulphated and silylated GPs. The stomach is an elongated sac-like structure with simple tubular glands surrounded by connective tissue. The neck cells of gastric glands synthesize a mixture of neutral and acidic GPs. The intestine is short with many intestinal villi. Many goblet cells are situated between superficial epithelial cells. The intestinal goblet cells were shown to secrete both neutral and acidic GPs.
