Definition

Noun: - The system of blood vessels and structures through which blood moves in a fetus: This term refers to the unique circulatory pathway in a developing fetus, which includes special structures like the ductus arteriosus and the foramen ovale. This system allows blood to bypass the non-functioning fetal lungs and receive oxygen and nutrients from the placenta.

Usage

This is a specialized medical/anatomical term. It is used in scientific, medical, and educational contexts to describe prenatal physiology. - It is typically used as a singular noun (e.g., the foetal circulation). - The spelling 'fetal circulation' (without the 'o') is more common in American English.

Examples

• Noun:
