Which bears a close structural relationship with the fossa ovalis?
The fossa ovalis is a depression in the interatrial septum of the heart that represents the remnant of the fetal foramen ovale. Structurally, the fossa ovalis is related to the foramen ovale in the fetal heart, which allows blood to pass from the right atrium to the left atrium before birth to bypass the nonfunctional lungs.
Thinnest portion of wall between to atria?
The thinnest portion of the wall between the two atria is the interatrial septum, which separates the right and left atria of the heart. This wall is thin and marked by a depression called the fossa ovalis, which is a remnant of the fetal foramen ovale.

What were the ligamentum arteriosum and the fossa ovalis called in the fetal heart?
the fossa ovalis was the foramen ovale and the ligamentum arteriosum was the ductus arteriosus. They each contributed to shunting blood away from the non-functional lungs in the fetus.
What do the ductus arteriosus and the foramen ovale become at birth?
Ligamentum arteriosum and the fossa ovalis. That is to say the arterial ligament and the oval depression (found in the left ventricle).
What were Two remnants of fetal structures are observable in the heart what were they called in the fetal heart?
Fossa ovalis and ligamentum. Fossa ovalis -> foramen lovale Ligamentum-> Ductus arteriosus
Where is the ligamentum arteriosum in the heart located?
The ligmentum arteriosum is the remnant of the ductus arteriosus in the fetal heart. The fossa ovalis is the remnant of the foramen ovale.
Formen ovale Ductus arteriosus Ductus venosus what will these shunts become in a newborn?
In a newborn, the foramen ovale will close and become the fossa ovalis. The ductus arteriosus will close and become the ligamentum arteriosum. The ductus venosus will close and become the ligamentum venosum.
What fetal structure gives rise to the fossa ovalis?
The fossa ovalis is a remnant of the fetal structure known as the foramen ovale. This structure is a small opening that allows blood to bypass the fetal lungs and flow from the right atrium to the left atrium, helping to maintain sufficient oxygen levels before birth.
What was the fossa ovalis called in the fetal heart?
In the fetal hear the fossa ovalis was known as the foramen ovale, which allows blood to pass from the right to the left atrium, thus bypassing the fetal lungs.
What is the name for the membrane that covers the foramen ovale after birth?
fossa ovalis
Which bears a close structural relationship with the fossa ovalis?

Structurally, the fossa ovalis is related to the foramen ovale in the fetal heart, which allows blood to pass from the right atrium to the left atrium before birth to bypass the nonfunctional lungs.
What two chambers do the fossa ovalis connect during fetal development?
Right atrium and Left atrium
What is the name of the thin spot between the atria?
no, you misunderstood it, the right answer is FOSSA OVALIS, I HAD IT ON A TEST TODAY AND I GOT IT RIGHT
Which two chambers are connected by the fossa ovalis during fetal development?
the right and left atrium of the fetal heart.
