Question

the umbilical cord contains _________.
a the fetal intestine
b two umbilical arteries and one umbilical vein
c only muscle tissue
d two umbilical veins and one umbilical artery

Explanation:

The umbilical cord is a vital connection between the fetus and the placenta. It contains two umbilical arteries, which carry deoxygenated blood from the fetus to the placenta, and one umbilical vein, which carries oxygenated blood from the placenta to the fetus. Option A is incorrect because the fetal intestine is not located within the umbilical cord. Option C is incorrect as the umbilical cord contains blood vessels (arteries and vein) along with Wharton's jelly (a type of connective tissue), not just muscle tissue. Option D has the incorrect number and type of vessels (it should be two arteries and one vein, not two veins and one artery).

Answer:

B. two umbilical arteries and one umbilical vein
