Basic Structure of the Villous Trees

  • M. Castellucci
  • P. Kaufmann


Nearly all maternofetal and fetomaternal exchange takes place in the placental villi. There is only a limited contribution by the extraplacental membranes. In addition, most metabolic and endocrine activities of the placenta have been localized in the villi (for review see Gröschel-Stewart, 1981; Miller & Thiede, 1984; Knobil & Neill, 1993).
