Fetal circulatory shunts
Understand what you see.
Directs fetal flow around much of the liver and non-ventilated lungs.
Zoom into the original labels. Practise pointing out each structure, then explain it aloud. Diagrams are teaching references; specimen appearance and slide staining vary.
How to recognise it.
- Placenta provides gas exchange
- Three major shunt pathways
- Right and left circulation have fetal connections
Point them out.
Tap a number to open its reference, zoom in and locate the structure. Numbers stay the same across views. This key follows landmarks visible in the reference images.
Think first. Then reveal.
Say your answer aloud before opening the suggested response.
01How do you identify fetal circulatory shunts?+
Placenta provides gas exchange. Three major shunt pathways. Right and left circulation have fetal connections.
02What does ductus arteriosus connect?+
Pulmonary trunk/left pulmonary artery region to descending aorta, distal to major arch branches.
03What is the function of foramen ovale?+
Permits right-to-left atrial flow, preferentially directing a stream of oxygen-enriched blood toward left heart.
04Which structures should you point out on this reference?+
Ductus venosus; Foramen ovale; Ductus arteriosus. Directs fetal flow around much of the liver and non-ventilated lungs.
