Fig. 4. Radiograms of Monkey Placental Circulation

Photographs of four of a series of radiograms made at 3.5, 4, 5, and 6 sec, respectively, following injection of a radiopaque dye into the right femoral artery of Monkey 12B, 111 days pregnant.

The insert in the third photograph (lower left) is a magnification (x4) of the area inclosed in the box.

The arrows indicate spurts of dye into the intervillous space. RA, renal artery; SA, spiral artery of endometrium; HA, hypogastric artery; UA, uterine artery.
