Can heavy metals pass through the placental barrier?
Most probably they will pass that way. They are toxic to the mother and foetus as well.
How does oxygen get from the air to cells of the fetus?
The mother is the "host" for the fetus until birth. All nutrition and growth support is done by virtue of the mother's umbilical cord. IT provides all oxygen and nutrition while connected.
Can the fetus metabolize glucose without oxygen?
First of all, the human fetus does have oxygen. The oxygen is obtained from the mother's blood via the placenta. But if the fetus did not have oxygen temporarily, s/he could still metabolize glucose. This would be done the same way that other humans metabolize glucose without oxygen--by converting it to lactic acid.
Who is the mother of chemistry?
Marie Anne Paulze Lavoisier is considered to be the mother of chemistry. She was married to Antoine Lavoisier, who was credited with discovering and naming the element oxygen. She helped him translate his work, thereby preserving his work.
What is the difference between dissolve oxygen and oxygen?
Dissolve oxygen is when oxygen is dissolved and oxygen is just normal oxygen!
What organ carries food and oxygen from the mother to the foetus?
g hjj
How does the foetus get food and oxygen?
The fetus gets food and oxygen through the umbilical cord.
What substance can be passed from the mother to the foetus?
Carbon dioxide and other such waste gases diffuse from the foetus and across the placenta into the mother's blood. Urea (excretory product) also diffuses into the mother's blood. (The substances in bold will answer question).
Why does a foetus's lungs don't work properly?
The foetus in embedded in fluid called amniotic fluid. Some times the foetus takes a breath in that fluid, just before the delivery. The result is disastrous. If the foetus is born with the fluid in the lungs, it is going to die in most of the cases. The foetus is getting all the oxygen and the nutrition from the mother. This is supplied through the placenta. So the lungs of the foetus are at rest in the womb of the mother.
What does a fetus need?
A growing foetus needs the cord because it gives the food and oxygen from the mother into the babyThe cord feeds the baby and gives the baby oxygen.All foetus's need a cord !
How does the fetus obtain food and oxygen?
The mother's blood supply enters the foetus via the umbillical cord and allows oxygen to diffuse from the mother's blood into the foetus.
How does oxygen travel from the air to the foetus?
Through the mother's lungs into her bloodstream, then across the placenta and through the umbilical cord to the fetus.
How are nutrients absorbed by the fetus?
The nutrients are absorbed through the placenta by the foetus. The foetus gets the oxygen and nutrition from the mother. The blood of the mother and foetus comes very close to each other in the placenta. Both are not mixed up. They are separated by very thin membrane. The surface area of the contact is very large as compared to the size of placenta.
How does the placenta acts as the lungs for the foetus?
the blood from the mother runs alongside the blood from the foetus ;the mother's blood carries food and oxygen to the baby .The oxygen reachs the lungs and carbon dioxide +waste exits through the umbilical cord . Although they run beside each other they never mix.
What does the foetus give to the mother?
pain.
What is the process which substances pass from the mother to the foetus?
The deoxygenated blood and the baby's waste products pass from the foetus to the mother. The mother can then dispose of these through her systems.
What is it called when a baby is inside the mother?
The mother is then pregnant. Its called a foetus.
