Microvessels of the anal canal in rats help tolements of the sphincteric apparatus of the rectum. They contribute to strengthening
of the obturatory function of the rectal sphincters. Morphometric indexes of the anal canal vessels change in different ways
depending on the section of the rectum and age. With increase of the muscular membrane of sphincters the diameter of
microvessels lumen in them becomes larger. It is noted the largest thickness of intaorgan vessels localization in interspincteric
zone and interspace between the inner and outer sphincters. It is established that lymphoid formations of the anal walls have
various localizations and thickness of localization depending on the age and sections of the rectum. Lymphoid formations in the
presphincteric section transitional zone are located as accumulations of lymphocytes. By the age of 3 months lymphoid nodules
are formed of them in the presphincteric section and in the transitional zone this process is completed by the age of 6 months.
Lymphoid structures are presented by diffuse lymphoid tissue in the inner sphincter. In various zones of the lymphatic canal
lymphoid accumulations have various form.
