why does a fetus have a hole in its heart?

This is called the FORAMEN (fancy word for hole) OVALE (fancy word for oval shape). This hole allows blood coming into the heart from the placenta to go directly to the left side of the heart to bring oxygen to the heart muscle and brain.

The heart structure of the fetus differs from the normal postnatal heart in that there is an opening in the atrial septum called the foramen ovale (FO in diagram). This allows most of the blood that enters the right atrium to flow into the left atrium instead of into the right ventricle.

Fetal anomalies, often referred to as birth defects, are structural changes to one or more parts of the fetus' body that increase the chance of stillbirth and can cause deficiencies in the child's health, development and quality of life.

Some have no belly button as a result of the surgery needed to correct abdominal problems at birth, often either an umbilical hernia, or a condition known as gastroschisis - born with the stomach and intestines poking through a hole in the abdominal wall.

In some cases, ectopic pregnancies have a heartbeat detected by sonogram in the fallopian tube. A bill that protects heartbeats or designates nonviable fertilized eggs as persons blatantly ignores the risk and rights to the heartbeat of the person who's pregnant.

In the early stages of pregnancy, you won't feel your baby's heartbeat in the stomach because your baby is protected by his own body, then further shielded by amniotic fluid, the amniotic sac, your uterus, muscles, and the skin of your body.

The fetus is connected by the umbilical cord to the placenta, the organ that develops and implants in the mother's uterus during pregnancy. Through the blood vessels in the umbilical cord, the fetus receives all the necessary nutrition, oxygen, and life support from the mother through the placenta.

Occasionally though, a heart murmur can be linked to a problem with the way that blood flows through the heart, or a structural problem with the heart. Even if an underlying problem is the reason for a baby's heart murmur, there is treatment available. A heart murmur very rarely proves fatal.

Function. The amniotic sac and its filling provide a liquid that surrounds and cushions the fetus. It allows the fetus to move freely within the walls of the uterus. Buoyancy is also provided.

Umbilical Hernia. An umbilical hernia is an abnormal bulge that can be seen or felt at the umbilicus (belly button). This hernia develops when a portion of the lining of the abdomen, part of the intestine, and / or fluid from the abdomen, comes through the muscle of the abdominal wall.

2. Your Belly Button Is Connected to Your Liver. ... Inside the growing fetus, those umbilical veins and arteries connect to the circulatory system, the liver and the bladder.

A ventricular septal defect (VSD) is a hole in the part of the septum that separates the ventricles (the lower chambers of the heart). The hole allows oxygen-rich blood to flow from the left ventricle into the right ventricle instead of flowing into the aorta and out to the body as it should.

The hereditary birth defect that was first documented by scientist Van Heusinger in 1864. Usually they're found on one side, but up to 50 per cent of people have them on both. According to Business Insider, one evolutionary biologist, Neil Shubin, says the holes could be an "evolutionary remnant of fish gills."

Patent Foramen Ovale (PFO) In most babies, the hole closes before birth as a natural flap seals shut. In some cases, this sealing will not occur until a week, or even several months, after a baby is born. When the septal wall does not close on its own, the hole is called patent foramen ovale (or PFO).

In other words the small hole in the womb simply heals itself. Since fertilisation of the egg takes place in one of the Fallopian tubes the womb perforation should not have any implications in relation to conception. Neither should it have any negative implications with regard to implantation in the wall of the womb.

The placenta is an organ that develops in your uterus during pregnancy. This structure provides oxygen and nutrients to your growing baby and removes waste products from your baby's blood. The placenta attaches to the wall of your uterus, and your baby's umbilical cord arises from it.

BAV is present at birth (congenital). An abnormal aortic valve develops during the early weeks of pregnancy, when the baby's heart is developing. The cause of this problem is unclear, but it is the most common congenital heart defect. BAV often runs in families.
