Tissues at and near the implantation site

General view of the tissues at and near the implantation site (No. 7801) to show the scab (Schlusscoagulum) of hemorrhagic exudate, actual hemorrhage underlying the scab, primary villus stems, blood-filled uterine glands, and early decidua. The embryo is evident and, near the opposite wall of the chorion, a vesicle presumed to be a detached part of the umbilical vesicle can be identified. Section 12-1-1.
