How does an embryo get the oxygen and nutrients it needs?
The unborn baby is connected to the placenta by the umbilical cord. All the necessary nutrition, oxygen, and life support from the mother’s blood goes through the placenta and to the baby through blood vessels in the umbilical cord.
How are wastes removed after birth?
Waste products and carbon dioxide from the baby are sent back through the umbilical cord blood vessels and placenta to the mother’s circulation to be eliminated.
How does baby in womb get oxygen?
The mother’s placenta helps the baby “breathe” while it is growing in the womb. Oxygen and carbon dioxide flow through the blood in the placenta. Most of it goes to the heart and flows through the baby’s body.
Which structure is responsible for supplying the fetus with nutrients and removing wastes?
The placenta is an organ responsible for providing oxygen and nutrients, and removing waste substances. It grows into the wall of the uterus and is joined to the fetus by the umbilical cord.
What happens if placenta isn’t working properly?
When the placenta malfunctions, it’s unable to supply adequate oxygen and nutrients to the baby from the mother’s bloodstream. Without this vital support, the baby cannot grow and thrive. This can lead to low birth weight, premature birth, and birth defects.
Can low oxygen cause miscarriage?
It is estimated that around two per cent of the human population — 140 million people — live in areas with low oxygen. In these conditions the placenta doesn’t always function properly and can cause miscarriage, preeclampsia and fetal growth restriction.
How do I know if my baby is not getting enough oxygen?
