| haemoendothelial placenta | <gynaecology> A haemoendothelial placenta is a type of placenta in which the inner lining (endothelium) of the capillaries of the chorion (membrane enclosing the foetus) comes in direct contact with the mother's blood. (09 Oct 1997) |

| haemomonochorial placenta | <obstetrics> A haemomonochorial placenta is a type of haemochorial placenta (placenta where the chorion, or membrane enclosing the foetus, comes in direct contact with the mother's blood) where a single layer of trophoblast tissue separates the mother's blood from the blood capillaries of the foetus.
