Morphological features of venous designs of proctal channels wall of human rectum
The venous plexus of the proctal channel of a human rectum is studied.Plexus submucous accepts venous blood not only from mucous, but also from a muscular cover. The anorectal vascular plexus is generated submucous by a network which venous vessels have the repeated thickenings separated by various sphincterlike narrowings. Proctal columns of human rectum represent the is muscular-vascular formations playing great value in expansion and narrowing of a proctal aperture.
