Plate 7

14 This photomicrograph of the decidua. Vera shows the enlarged and tortuous glands filled with secretion. The superficial venous sinuses are dilated. The spiral arteries extend to the surface of the vera. The superficial half of the Vera is edematous. Surrounding the spiral arteries the deeidual tissues are more dense. x 54.1.

15 The distal portion of the spiral artery entering the penetration zone is filled with blood. The proximal portion (not shown in the photograph) contains no blood and is constricted. The artery ends as an endothelial tube in the penetration zone. See figures 18 and 19. X 32.4.

16 A spiral artery in the lateral penetration zone divides into two branches. One branch is filled with blood and the other is constricted and empty. X 68.

17 The gland epithelium with syncytial elements adjacent is destroyed in places. A capillary has been disrupted and its free end projects into the gland lumen. The latter is filled with blood. X 395.
