Description
Gross and histological changes of 153 camel foetal hearts were investigated. The present study has shown that compartmentalization of the camel foetal heart into left and right ventricles and the left and right atria was completed by 75 days of gestation. Internally the interventricular septum, and the interatrial septae were completely formed. The formation of interatrial septum is simultaneous with the growth of interventricular septum; there was no evidence of interventricular foramen at 75 days of gestation. Furthermore, the foramen ovale persist up to the third trimester of the foetal stage of development. During first trimester cellular proliferation was recorded, which decreased toward third trimester of foetal development.The arrangement of muscle fibres in this study was from random in the first trimester to a more parallel arrangement by third trimester of pregnancy. It is concluded that the heart of camel foetus has reached a functional state of development at third trimester of pregnancy.
