The Prospective Mother, a Handbook for Women During Pregnancy There is no doubt whatever that the mother's blood surrounds the placental villi but never enters the child. The Prospective Mother, a Handbook for Women During Pregnancy Each villus contains a loop of blood-vessels, and another vessel, the lacteal, so called from the Latin word lac, milk, because of the milky appearance of the fluid it contains. A Practical Physiology The other, and equally important, task of the villi, the majority of which dip into the mother's blood, is to transmit substances to and from the embryo. The Prospective Mother, a Handbook for Women During Pregnancy The tiny lakes, in which the villi hang, are thus made a part of the mother's circulation and as such are regularly replenished with purified blood. The Prospective Mother, a Handbook for Women During Pregnancy The blood-vessels in the fingers, to go a step farther, represent the blood-vessels which exist within the villi, connecting with the umbilical cord, and passing by that route to the body of the child.
