## Core Concept
Uterine blood flow increases significantly throughout pregnancy to accommodate the growing fetus and prepare for childbirth. This increase is crucial for the delivery of oxygen and nutrients to the fetus and for the removal of waste products. At term, which refers to the end of pregnancy (around 37 to 42 weeks of gestation), uterine blood flow has reached its peak.

## Why the Correct Answer is Right
The correct answer indicates that uterine blood flow at term is approximately 600-800 mL/min. This increase in blood flow is essential for supporting the metabolic needs of the fetus and the uterus. The uterine arteries, which are the primary suppliers of blood to the uterus, undergo significant changes during pregnancy, including vasodilation, to accommodate this increased demand. The increased blood flow helps in ensuring that the fetus receives adequate oxygen and nutrients.

## Why Each Wrong Option is Incorrect
- **Option A:** This option suggests a much lower blood flow (less than 100 mL/min), which is not sufficient to support the metabolic demands of the fetus and uterus at term.
- **Option B:** This option suggests a moderate increase (around 400-500 mL/min), which underestimates the actual increase in uterine blood flow observed at term.
- **Option D:** This option suggests an excessively high blood flow (over 1200 mL/min), which, while indicating an understanding of increased blood flow, overestimates the typically reported values at term.

## Clinical Pearl / High-Yield Fact
A key clinical point to remember is that any significant reduction in uterine blood flow can lead to fetal growth restriction and other complications. Uterine blood flow is a critical parameter that can be monitored during pregnancy, especially in cases where there is a concern for fetal well-being.

## Correct Answer: C. 600-800 mL/min.
