Chapter 28, Problem 7
The umbilical vein carries
(a) waste products to the placenta
(b) oxygen and food to the fetus
(c) oxygen and food to the placenta
(d) oxygen and waste products to the fetus
Verified step by step guidance1
Understand the role of the umbilical vein in fetal circulation. The umbilical vein is a blood vessel that carries blood between the placenta and the fetus.
Recall that the placenta is the site where the fetus receives oxygen and nutrients from the mother's blood and removes waste products.
Identify that veins generally carry blood toward the heart or, in this case, toward the fetus, while arteries carry blood away from the heart or fetus.
Recognize that the umbilical vein carries oxygenated blood rich in nutrients from the placenta to the fetus, supplying the fetus with what it needs for growth and development.
Based on this understanding, select the option that states the umbilical vein carries oxygen and food (nutrients) to the fetus.
Key Concepts
Here are the essential concepts you must grasp in order to answer the question correctly.
Function of the Umbilical Vein
The umbilical vein carries oxygenated blood and nutrients from the placenta to the fetus. It is the primary vessel responsible for delivering essential substances needed for fetal growth and development.

Introduction to Veins
Role of the Placenta in Fetal Circulation
The placenta acts as an interface between maternal and fetal blood supplies, facilitating the exchange of oxygen, nutrients, and waste products. It supplies oxygen and nutrients to the fetus and removes carbon dioxide and metabolic wastes.

Difference Between Umbilical Vein and Umbilical Arteries
Umbilical arteries carry deoxygenated blood and waste products from the fetus to the placenta, while the umbilical vein carries oxygenated blood and nutrients from the placenta to the fetus. Understanding this distinction is key to answering questions about fetal circulation.
