Why does the mass of the placenta increase as the foetus develop?
The mass of the placenta increases as the fetus develops to support the growing fetus' nutritional and oxygen needs. This increase in mass is essential for the placenta to effectively exchange nutrients, waste, and gas with the mother's bloodstream to support the fetal growth and development.
Why the mass of the placenta increases as the foetus develops.?
To hold the growing fetus .
Why the mass of the placenta increases as the foetus develops?
To hold the growing fetus .
What part of the placenta will become the trophoblast and the blastocyst?
The outer layer of the blastocyst will become the trophoblast, which later develops into the placenta. The inner cell mass of the blastocyst will give rise to the embryo and eventually the fetus.
In which lifework period on the graph does the mass of the fetus increase most rapidly?
The mass of the fetus increases most rapidly during the third trimester of pregnancy. This is when the fetus experiences significant growth and development, resulting in a noticeable increase in mass and size.
What portion of blastocyst develops into the body of the embryo?
The inner cell mass of the blastocyst develops into the body of the embryo. This inner cell mass will give rise to the different cell types and structures that form the developing fetus.
What does the separation from the inner cell mass from the trophoblast form?
The separation of the inner cell mass from the trophoblast during early embryonic development forms two distinct structures: the embryoblast and the trophoblast itself. The embryoblast eventually develops into the embryo, while the trophoblast contributes to the formation of the placenta, facilitating nutrient exchange between the mother and the developing fetus. This differentiation is crucial for establishing the early stages of pregnancy and supporting fetal development.
Were does the placenta form?
The placenta develops in the uterus after the zygote has implanted in the Uterine wall. This wall develops into the placenta during pregnancy. If implantation does not occur the wall will be sloughed off in the next menstrual cycle
Do you increase or decrease in mass?
you increase or decrease mass by taking the mass out
What does the fetus have to do with pregnancy?
The fetus is what they call the unborn baby after 3 months of growing in the uterus. At that time it is now considered an unborn child or fetus instead of a blacocyst or mass growth of cells.
What best defines blastocyst?
A blastocyst is an early-stage embryo with about 70-100 cells, consisting of an outer layer of cells that will become the placenta and an inner cell mass that will develop into the fetus. It forms a few days after fertilization as the embryo travels down the fallopian tube towards the uterus for implantation.
How do the cells in a blastocyst as it becomes an embryo?
Cells in a blastocyst start to differentiate into specific cell types, forming layers called the inner cell mass and the trophectoderm. These cells will give rise to different tissues and organs as the embryo develops. The inner cell mass forms the embryo itself, while the trophectoderm will become the placenta.
