Greetings Mohamed:
The lamina propria brings small blood vessels and lymphatics close to
the epithelium lining the large and small intestines. This allows
nutrients to be passed back and forth and for the immune system to
monitor any antigens that cross the epithelium. The relationship between
the immune system and the contents of the GI tract is very complex.
Lymph nodules in the lamina propria would make it thicker in some
regions than in other regions. Whether the thickening you refer to is
pathological or just the normal response to a variety of factors is
difficult to say.

dear histonetters
i have a quistion please regarding the thickness of lamina propria in small or
larg intestine.
what is the significant of it?? does it mean inflamation and pathological
condition or mean more size and so absorption of nutrients? i mean does the
thickning is favorable or not?
