chorionic villous tree

placental villous tree

A tree-like structure formed by chorionic villi that sprouts from the chorionic plate in the placental disc. The arborous shape of the chorionic villous tree provides maximal contact area with maternal blood in the intervillous space.

Frequently Asked Questions

What is the chorionic villous tree?

The chorionic villous tree is the organized, branching system of chorionic villi extending from the chorionic plate into the intervillous space, forming the primary functional unit of the placenta.

Where is the chorionic villous tree located?

The villous tree occupies the intervillous space of the placenta, anchored to the chorionic plate with its branches extending downward toward the basal plate.

What is the function of the chorionic villous tree?

The villous tree dramatically increases the surface area available for maternal-fetal exchange of oxygen, nutrients, and metabolic wastes across the placental barrier.

What is the chorionic villous tree connected to?

The tree is connected centrally to the chorionic plate and umbilical vessels, while its terminal branches are surrounded by maternal blood in the intervillous space.

Why is the chorionic villous tree clinically important?

The structural integrity of the villous tree determines placental efficiency; abnormalities correlate with intrauterine growth restriction, preeclampsia, and fetal complications.
