1 The maternal endometrium response to trophoblast invasion is called the decidual reaction.

true
false

2 The human placenta is classified as :

Endotheliochorial
Haemochorial
Epitheliochoria
Mesoeliochorial

3 Stem villi - or terminal villi, are the region of main exchange, surrounded by maternal blood in intervillous spaces.

true
false

4 The 4 cellular layers separating maternal and fetal blood in sequence are:

spiral artery wall, Nichbaur layer, cytotrophoblast and Hofbaur layer
syncitiotrophoblast, cytotrophoblast, villi connective tissue and fetal capillary endothelium
maternal lacuna, trophoblast layer, endothelial and fetal red blood cell
fetal capillary endothelium, villi connective tissue, cytotrophoblast and syncitiotrophoblast
