Abstract

The research consists of a macroscopic study on the arterial and vein system of umbilical funiculus and placenta of cats fetus and placental characterization as to type, zonary placenta, which presents in 62.5% of cases a fissure at distal area of umbilical funiculus. The umbilical funiculus is formed by a joustfetal area, joustplacental area and middle area, finding in your histological court: two arteries, a vein, two yolk sac pedicles and two pedicle allantois.
