The placenta has several functions in development of the human embryo. # It is an endocrine organ, i.e an organ which secretes hormones from endocrine glands which are ductless. # It is involved in the exchange of substances between the maternal and fetal circulation, e.g. glucose, water, inorganic ions, antibodies, fatty acids, amino acids, etc. # It acts as a barrier bwtween the fetal and maternal circulation for the following reasons - firstly because the mother may have a different blood type to the fetus (i.e. Rhesus Negative when the baby is Rhesus positive) and this stops her from mounting an immune response against the fetus. Secondly because the higher blood pressure of the mother would damage the fetal capillaries, which are very fragile if the placenta wasn't there to act as a barrier. # The blood flow in maternal and fetal capillaries in the placenta is counter-current, in other words they flow in opposite directions, maximising the concentration gradient between them, which is essential for transport of substances by the mechanism of diffusion (e.g. of waste gases like CO2) and facilitated diffusion (e.g of glucose)
caca
it extracts food and oxygen from the uterine wall of the mother to the fetus.
Both of these
If the placenta don't function the embryo will die.
For nine months the placenta feeds and nourishes the fetus while also disposing of toxic waste.
The placenta is for nourishing the embryo.
For nine months the placenta feeds and nourishes the fetus while also disposing of toxic waste.
In a fetal pig, when the lungs do not function, oxygen exchange occurs through the placenta. The placenta transfers oxygen from the mother's blood to the fetal blood, bypassing the need for lung function.
The main function of placenta in pregnancy is to supply your baby with sufficient nourishment. Generally it is found to evaluate around one-sixth of your newborn's weight. Every minute during the pregnancy, approximately about 550 ml of blood gets pushed into the uterus to replace enough nutrients with the placenta for your baby.
The structure of the placenta is related to its functions because its functions is to support the embryo/foetus in ways such as providing it with nourishment, and oxygen which explains the relevance of the placenta to its function of supporting the growing individual.
It provides food to embryo .
It nourishes the fetal pig.
