Pregnancy diet

Some foods should be avoided entirely, while others should not be eaten at all. These are the foods and drinks you should avoid while pregnant.

High mercury fish

Mercury is highly toxic. Mercury is highly toxic and has not been proven safe to be exposed. It is most often found in polluted waters.

It can cause damage to your nervous system and immune system. Even in low amounts, it can cause severe developmental problems in children.

Fish that is undercooked or not cooked properly

This one is not easy for sushi lovers, but it is important. Many infections can be caused by raw fish, particularly shellfish. These infections can be viral, bacteria, or parasitic.

These infections can only affect you and cause weakness and dehydration. You may pass on other infections to your baby, which can have serious or fatal consequences.

Meat that has been undercooked, raw, or processed

Raw fish can also be affected by undercooked meat. Consuming raw or undercooked meat can increase your risk of contracting several parasites or bacteria, such as Listeria, Toxoplasma and Salmonella.

Bacteria can pose a threat to the health of your baby, leading to stillbirth, severe neurological diseases, such as blindness or intellectual disability, and possibly even epilepsy.

Raw eggs

Salmonella bacteria can be found in raw eggs.

Salmonella infections can cause fever, nausea, vomiting and stomach cramps.

In rare cases, however, cramps may occur in the uterus and cause premature birth or stillbirth.

Organ meat

Organ meat is an excellent source of many nutrients.

Vitamin A, vitamin B12 and vitamin A are all good for your baby. Pregnancy is not a good time to eat too much animal-based vitamin B12 (preformed vitaminA).

Caffeine

Perhaps you are one of millions who enjoy their morning cup of coffee, tea or cocoa. When it comes to caffeine, you’re not the only one.

According to the American College of Obstetricians and Gynologists (ACOG), pregnant women should limit their caffeine intake to 200 mg per day.

Caffeine is quickly absorbed and easily passes into the placenta. High levels of caffeine can be caused by the fact that babies and their placentas lack the main enzyme required to metabolize it.

What is the function of the fetal circulatory systems?

The mother is the only source of nourishment and oxygen for the unborn baby (fetus). Because the fetus does not breathe air, blood circulation is different after birth.

The placenta (or placenta) is an organ that grows and implants in the mother’s womb during pregnancy. The umbilical cord connects the unborn baby to the placenta.

All of the nutrients, oxygen, and life support that a mother receives from her blood flows through the placenta to the baby via blood vessels in the umbilical chord.

The umbilical cord blood vessels, placenta and waste products from the baby are returned to the mother’s circulation for elimination.

The baby’s lungs don’t get used while still in the uterus. The baby’s liver has not developed fully. Circulating blood flows in different ways and through special openings called “shunts” and bypasses the liver and lungs.

This pathway is how blood flows to the unborn baby.

Through the umbilical cord, oxygen and nutrients are transferred from the mother to the fetus via the placenta.

The enriched blood flows into the umbilical vein to the baby’s liver. It then moves through the shunt known as the ductus venenosus.

Some of this blood can then be sent to the liver. Most of the oxygenated blood is pumped to the inferior vein cava, which then flows into the right atrium.
