The placenta is a unique vascular organ that receives blood supplies from both the maternal and the fetal systems and thus has two separate circulatory systems for blood: (1) the maternal-placental (uteroplacental) blood circulation, and (2) the …

One of the critical features of the developing embryonic–maternal interface is the establishment of a uteroplacental circulation that serves as the medium for bringing food and oxygen to and removing wastes from the embryo.

2020年8月15日 · The uteroplacental circulation is unique: it is in essence two distinct circulatory systems in parallel (foetoplacental and maternoplacental). At term, it receives about 800ml/min of blood flow, or something like 14-15% of the total cardiac output.

2014年9月16日 · Pregnancy is a dynamic process associated with significant physiological changes in the cardiovascular system. These changes are mechanisms that the body has adapted to meet the increased metabolic demands of the mother and fetus and to ensure adequate uteroplacental circulation for fetal growth and development.

The uteroplacental circulation provides the necessary nutritional resources to the uterus, placenta, and fetus during gestation; thus, proper development of the uteroplacental circulation is critical for a successful pregnancy.

Abnormal placental function is well-established as a major cause for poor pregnancy outcome. Placental blood flow within the maternal uteroplacental compartment, the fetoplacental circulation, or both, is a vital factor in mediating placental function.

2021年8月11日 · Uteroplacental blood flow increases as pregnancy advances. Adequate supply of nutrients and oxygen carried by uteroplacental blood flow is essential for the well-being of the mother and growth/development of the fetus.

This circulation is critical in fetal development, yet the patterns of maternal flow within the intervillous space (IVS) and details of venous return remain largely unknown. ... Rheological and Physiological Consequences of Conversion of the Maternal Spiral Arteries for Uteroplacental Blood Flow during Human Pregnancy.

2001年11月1日 · Color Doppler imaging in vivo assessment of anatomy and physiology of the early uteroplacental circulation

2021年8月11日 · Uteroplacental vessels undergo adaptation to accommodate increased uteroplacental blood flow in pregnancy. Observations from human and animal studies suggest that this adaptation involves functional alterations in both vascular smooth muscle cells and endothelial cells.
