Umbilical Cord Question and Answers â Questions and Answers
Question 1: What is the structure that serves as a transient organ to provide substance exchange between the mother and fetus.
- uterus
- amniotic sac
- umbilical cord
- placenta (Correct answer)
Correct answer: placenta
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.
- contains blood vessel (Correct answer)
- to transport substances between the fetus and the mother (Correct answer)
- a tube that connects placenta and the fetus (Correct answer)
- a thin and strong membrane
- prevents blood form mother and fetus from mixing
Correct answer: contains blood vessel
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.
- Amnion (Correct answer)
- Placenta (Correct answer)
- Umbilical cord (Correct answer)
- Sperm duct
- Fallopian tube
Correct answer: Amnion
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?
- to connect the fetus and the placenta
- acts as cushion to support and protect from mechanical shock (Correct answer)
- to allow exchange of substances between the fetus and the mother
- to form a sac and enclosed the fetus
Correct answer: acts as cushion to support and protect from mechanical shock
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.
- nutrients
- carbon dioxide (Correct answer)
- oxygen
- urea (Correct answer)
- antibodies
Correct answer: carbon dioxide
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.
Question 6: Which organ contains the fetus' blood vessels?
- amniotic fluid
- uterus
- placenta
- umbilical cord (Correct answer)
Correct answer: umbilical cord
The umbilical cord is the direct connection between the fetus and the placenta. It contains the fetal blood vesselsâtwo umbilical arteries and one umbilical veinâthat carry blood to and from the fetus. These vessels enable the exchange of substances with the mother via the placenta, making the umbilical cord the organ containing the fetus's blood vessels.
Question 7: This object is a strong, thin membrane that creates a sac around the developing fetus in the uterus.
- amniotic fluid
- umbilical cord
- placenta
- amnion (Correct answer)
Correct answer: amnion
The amnion is a strong, thin membrane that forms the innermost sac around the developing fetus. This sac, filled with amniotic fluid, provides a protective environment for the fetus, cushioning it and allowing for proper development. It is distinct from the placenta or umbilical cord, which have different functions.
