Umbilical Cord Question and Answers

Question 1

What is the structure that serves as a transient organ to provide substance exchange between the mother and fetus.

Accepted Answer

placenta

Answer

The placenta is a temporary organ that develops in the uterus during pregnancy. It serves as the primary site for nutrient, gas, and waste exchange between the mother and the fetus, facilitating the baby's growth and development. This transient organ is crucial for sustaining the fetus throughout gestation.

Question 2

Select the statements regarding the umbilical cord that are true.

Accepted Answer

contains blood vessel

Answer

The umbilical cord is a vital structure connecting the fetus to the placenta. It contains blood vessels, specifically two arteries and one vein, which are responsible for transporting oxygen and nutrients from the mother to the fetus, and waste products from the fetus back to the mother. It acts as the essential lifeline for substance exchange.

Question 3

Pick the uterine structures that are important for the growth of the fetus.

Accepted Answer

Amnion

Answer

The amnion forms the amniotic sac, which holds the amniotic fluid protecting the fetus. The placenta is crucial for nutrient and waste exchange, while the umbilical cord connects the fetus to the placenta, facilitating this exchange. All three are essential uterine structures supporting fetal growth and development.

Question 4

What use does amniotic fluid serve?

Accepted Answer

acts as cushion to support and protect from mechanical shock

Answer

Amniotic fluid surrounds the developing fetus within the amniotic sac. Its primary function is to provide a protective cushion, shielding the fetus from external mechanical shocks and impacts. It also allows for fetal movement and helps regulate temperature, creating a stable environment for growth.

Question 5

Describe the compounds that are transferred from the fetus to the mother through the placenta.

Accepted Answer

carbon dioxide

Answer

The placenta facilitates the transfer of waste products from the fetus to the mother's bloodstream for excretion. Specifically, carbon dioxide, a byproduct of fetal respiration, and urea, a nitrogenous waste product from fetal metabolism, are transferred from the fetus to the mother through the placenta. The mother's body then processes and eliminates these wastes.
