The extraembryonic yolk sac (YS) ensures delivery of nutritional support and oxygento the developing embryo but remains ill-defined in humans. We therefore assembled acomprehensive multiomic reference of human YS from 3-8 post-conception weeks by integratingsingle-cell protein and gene expression data. Beyond its recognized role as a site of hematopoiesis,we highlight roles in metabolism, coagulation, vascular development, and hematopoieticregulation. We reconstructed the emergence and decline of YS hematopoietic stem/progenitor cellsfrom hemogenic endothelium and revealed a YS-specific accelerated route to macrophageproduction that seeds developing organs. The multiorgan functions of YS are superseded asintraembryonic organs develop, effecting a multifaceted relay of vital functions as pregnancyproceeds.One-Sentence Summary: The human yolk sac is a key staging post in a relay of vitalorganismal functions during human pregnancy.
