Summary
This study reviews computational models of placental blood flow and nutrient transport. Understanding these complex fluid dynamics is crucial for diagnosing and treating fetal development disorders.
Area of Science:
- Physiology
- Biomedical Engineering
- Computational Fluid Dynamics
Background:
- The placenta facilitates vital nutrient and gas exchange between mother and fetus.
- Fetal blood circulates within villous trees, surrounded by maternal blood.
- Disruptions in placental structure and function can lead to pregnancy complications.
Purpose of the Study:
- To survey recent advancements in modeling placental fluid mechanics and transport.
- To highlight emerging challenges in simulating placental blood flow and solute uptake.
- To provide a comprehensive overview of computational approaches in placental research.
Main Methods:
- Review of computational fluid dynamics (CFD) models.
- Analysis of simulations for maternal and fetal blood flow.
- Examination of solute transport models within placental vasculature.
Main Results:
- Recent imaging and computational tools have enabled detailed simulations of placental flows.
- Models capture maternal blood jets entering porous villous structures.
- Simulations illustrate solute uptake by fetal blood in complex capillary networks.
Conclusions:
- Computational modeling is essential for understanding placental function and disease.
- Further research is needed to address challenges in simulating complex placental hemodynamics.
- Advanced modeling can improve diagnosis and treatment of placental dysfunction.

01:14Fetal Circulation
969
Fetal circulation is a unique system that facilitates the exchange of gases, nutrients, and waste products between the developing fetus and the mother. This intricate process takes place through a special organ called the placenta.
Two umbilical arteries transport blood from the fetus to the placenta. At the placenta, the blood absorbs oxygen and nutrients while simultaneously eliminating waste products. This oxygen-enriched and nutrient-rich blood then returns to the fetus through one...

01:07Development of Blood Vessels
583
The development of the vascular system in a fetus is a complex and intricate process that begins as early as 15 to 16 days post-conception. This process starts outside the embryo, specifically in the mesoderm of the yolk sac, chorion, and connecting stalk. Approximately two days later, the formation of blood vessels occurs within the embryo itself.
The initial formation of this system is facilitated by the small amount of yolk present in the ovum and yolk sac. Blood vessels originate from...

01:29Blood Flow
69.7K
Blood is pumped by the heart into the aorta, the largest artery in the body, and then into increasingly smaller arteries, arterioles, and capillaries. The velocity of blood flow decreases with increased cross-sectional blood vessel area. As blood returns to the heart through venules and veins, its velocity increases. The movement of blood is encouraged by smooth muscle in the vessel walls, the movement of skeletal muscle surrounding the vessels, and one-way valves that prevent backflow.

01:25Physiological Barriers
3.5K
Physiological barriers are semi-permeable cellular structures restricting drug diffusion into intracellular compartments and tissues. There are six types of physiological barriers: blood endothelial, cell membrane, blood-brain, blood-cerebrospinal fluid (CSF), blood-placenta, and blood-testis barriers.
The blood endothelial barrier is the most porous of these. It allows all small ionized, un-ionized, and lipophilic molecules to pass through the endothelial lining into the interstitial space...

01:15Transcytosis of IgG
2.8K
Transcytosis is the process in which molecules are internalized by endocytosis, transported across the cell, and released through exocytosis from the opposite end of the cell. Molecules such as insulin, immunoglobulins, and certain nutrients are transferred through the recycling endosomes by recycling and transcytosis.
IgG molecules from a mother undergo transcytosis starting around 13 weeks of gestation. The amount of IgG transferred and entering the fetal blood circulation increases with...

2.7K
Hemoglobin (Hb) is a crucial molecule in the human body, consisting of four polypeptide chains, each bound to an iron-containing heme group. This unique structure enables hemoglobin to bind to oxygen, with each molecule capable of combining with four molecules of oxygen, leading to rapid and reversible oxygen loading. When fully loaded with oxygen, it is called oxyhemoglobin, while hemoglobin that has released oxygen is called reduced hemoglobin or deoxyhemoglobin. As hemoglobin binds oxygen,...
