Pregnancy Differentiation and Birth
Fertilization (first week) - The process by which gametes from two parents combine to form one new cell (zygote). After Fertilization the zygotes continues down to the oviducts toward the uterus on its way approximately 24-36 hours after Fertilization the process of mitosis begins.
Implantation – embryo attaches itself to the thickened lining of the uterus.
Cleavage – When the cell divides rapidly after the egg is fertilized.
Blastocyst – developing of the embryo and forming in outer and inner layer.
Placenta- When the blood vessels reach organ that is present only during pregnancy.
Gastrula – when cell begins to specialize to form an embryo the structure of the developing embryo.
The yolk sac is supplying the nutrients to the embryo for about the first two months of developments.
Amnion-
the fluid-filled membrane enclosing the baby in the womb
Allantois- helps remove waste from the embryo. A tubular extension of the endoderm of the yolk sac that extends with the allantois vessels into the connecting stalk of the embryo Umbilical cord - The flexible cordlike structure connecting a fetus at the navel with the placenta and containing two umbilical arteries and one vein that transport nourishment to the fetus and remove its wastes. It’s also called funis. umbilical -cord
A temporary lifeline connecting the unborn child with the placenta, channelling nourishment from the mother and removing wastes from the baby.
The first trimester starts with the first day of your last menstrual period, and ends roughly 13 or 14 weeks later. Three different methods are used to divide up a pregnancy into the three trimesters. Each methods results in slightly different spans for the trimesters.
The development method uses the developmental stages to divide up a pregnancy. The second trimester begins at 12 weeks and the third at 27 weeks.
From LMP to 12 weeks, the embryo develops all the major organs.
From 12 weeks to 27
