Arteriae and veins of the fore stomach walls and third stomach of cattle at early postnatal ontogenesis

In the submucosal base intramural arteriae are divided up to the third orders at two-week calves, rich arterial vascularization of all parts of fore stomach alveus are marked. Venous channel of fore stomach is presented by single small veins, asymmetrical and branchy in a form. Among all parts of fore stomach venous channels have maximum power density in the fore stomach alveus. Vascularization of third stomach is in closed independence with pecularity of the structure of mucous membrance due to the availability of large, medial, small and the smallest leaves. Arteriae and veins of third stomach are subdivided into long, medial and short ones. Unlike the arteriae the veins are pair.
