When the nurse describes the duct that carries the ovum from the ovary to the uterus, what is the nurse discussing? the:
zimovet [89]

The nurse is discussing about fallopian tube. One of two long, slender tubes that connect the ovaries to the uterus are called fallopian tubes.

<h3>What is fallopian tube?</h3>

One of two long, slender tubes that connect the ovaries to the uterus are called fallopian tubes. Eggs pass from the ovaries, through the fallopian tubes, to the uterus.

Fallopian tubes are an important passageway for an egg and a sperm to meet and for a fertilized egg (embryo) to make its way to your uterus. The health of  fallopian tubes impacts one's fertility.  Blocked or damaged fallopian tubes can make it difficult for individuals \ and couples to become pregnant.

The fallopian tubes play a crucial role in the interaction between an egg and a sperm as well as the journey of a fertilized egg (embryo) to the uterus. Your fertility is influenced by the condition of your fallopian tubes.

A single fallopian tube can serve two functions, despite the fact that women typically have two fallopian tubes, which are both utilized to move the developed egg from the ovary to the uterus (hoping to meet a healthy sperm along the route..). (more on that below).
