It arises beneath the hind-end of the fore-gut, at the point of divergence of the folds of the splanchnopleure, and so lies within the pleuro-peritoneal cav- ity, and is derived from the mesoblast. At the beginning the heart consists of two solid columns ununited in front at first; later, these fuse, in part, so that they have been compared with an inverted Y, in which the heart itself would correspond to the lower stem of the letter (a) and the great veins (vitelline) to its main limbs. The solid cords of mesoblast become hollow prior to their coalescence, when the two tubes become one. ^ >MUM«i#i(biN4«M«i^iirftK^' â *iiw»,«iw)»WM»i »,k fiimim.
