Abstract

The agouti is a wild rodent found in the south of Central America and in tropical regions of South America, especially in the Northern, Northeastern and Southeastern regions of Brazil. These animals represent an important socio-economic factor in the North and Northeastern regions of Brazil since they provide animal protein. For this paper 07 agouti (Dasyprocta aguti) placentas were used, in differents stages of gestation. The placenta presents a spherical shape and lobular structure connecting to the uterus by means of a mesoplacenta. Fetal blood flows from the interlobium to the center of the lobe, that is, centripetally, while maternal blood flows centrifugally.
