Popis: | The branching and the arrangement of the placental arteries and veins of 20 Nelore bovines were studied. An anastomosies between the 2 arteries in the funiculus umbilicalis appeared in 75% of the cases (70% single and 5% double). The types of vasculo-cotyledonary distribution were based on the arrangements of arteries and veins and on their relationship with the cotyledons. A cotyledon supplied by a single artery is drained by multiple veins, and in a few cases the arteries and veins supplied and drained, respectively, cotyledons of the pregnant and non-pregnant uterine horns. |
