→‎Placental Expulsion

Line 48: Line 48:

* Domestic animals normally eat the afterbirth.

** Not the mare or camelids.

−

* Expulsion of the foetus requires that the chorionic villi become dislodged from the crypts of the maternal side of the [[Female_Reproductive_Tract_-Placenta_-_Anatomy_%26_Physiology|placenta]].

−

** Brought about by powerful vasoconstriction of arteries in the villi.

−

*** Vasoconstriction reduces pressure and allows villi to be released from crypts.
