14. Structure of the porcine placenta. Nutrient exchange between

maternal and fetal circulation (green arrow) occurs across six tissue

layers (maternal endothelium, maternal connective tissue, maternal

endometrial epithelium, trophoblast, fetal connective tissues, and fetal

endothelium). Fetal exchange capillaries are located below trophoblast

and in trophoblast ridges. Larger conducting vessels in the fetal placenta

are surrounded by smooth muscle and are located closer to the amnion.

Areloae are specialized exchange areas of fetal placenta that develop

opposite secretory glands of the maternal endothelium. Structure and

nutrient transporter expression were measured in the fetal layers of the

porcine placenta (shaded regions) in this study
