Time-dependent viscoelastic properties along rat small intestine

Table 1 Average opening angle at 45 and 60 min and maximal luminal area and wall thickness for rings cut from rat duodenum, jejunum, and ileum from rat intestine (mean±SE)

	Duodenum	Jejunum	Ileum
Angle (45 min)	211.1±17.2	128.5±10.1b	145.9±9.2b
Angle (60 min)	220.8±12.9	143.9±8.9b	151.4±9.3b
Lumen diameter (mm)	0.86±0.03	0.73±0.04a	0.89±0.03
Wall thickness (mm)	0.88±0.03	0.72±0.06a	0.66±0.02b
