How do sperm get through the cervix?
Sperm travel through the cervix into the uterus by swimming through the cervical mucus. The cervix produces a special type of mucus that is more conducive to sperm movement during ovulation. Additionally, sperm can also be helped by uterine contractions that draw them into the uterus.
What is a good sentence for divergent boundaries?
My girlfriend broke up with me, saying that we were developing divergent boundaries. In plate tectonics, divergent boundaries are linear features that exist between two tectonic plates that are moving away from each other.
What is the process involving cell rearrangements to form the three primary germ layers?
During gastrulation in embryonic development, cells undergo rearrangements to form the three primary germ layers (ectoderm, mesoderm, endoderm). This process involves invagination, ingression, and delamination of cells. Invagination occurs when cells move inward, ingression refers to individual cells leaving the surface epithelium and entering the interior, and delamination involves cells moving between epithelial layers. Together, these movements help establish the three germ layers that give rise to different tissues and organs in the developing embryo.
Which way you are moving is you are changing longitude?
If you are changing longitudes while moving eastward, you are moving in an easterly direction. If you are changing longitudes while moving westward, you are moving in a westerly direction.
How can you determine the direction in which a comet is moving?
You can determine the direction in which a comet is moving by observing its motion against the background stars over a period of time. If the comet appears to be moving eastward against the stars, it is moving in a westerly direction in relation to the Earth. If it appears to be moving westward, it is moving in an easterly direction from Earth's perspective.
What on the inner lining of the fallopian tube aids in moving a developing embryo?
The uterine tube is called the fallopian tube and the lining is made up of tiny hairlike, fingers called fimbria. The fimbria move the developing embryo along the fallopian tube to the uterus where it will embed itself. Here it will grow and develop until it is ready to be born in about 9-10 months..
What is embryo transfer?
Embryo transfer is the process of moving embryos fertilized outside the body (through in vitro fertilization) into a woman's body for conception and pregnancy.
What color is the embryo?
The precise color of an embryo will change as it develops, but for much of development, pigmented cells have not yet formed, so the embryo will mostly be white-pink in color. The embryo proper will be white or off-white, but the circulatory system forms pretty early so the red of the blood moving through the embryo gives it a pinkish hue.
Placenta formation?
Many people have mistaken ideas about how a growing embryo eats and breathes in the uterus.From the earliest stages of its development, the growing embryo requires nutrition and oxygen, and a disposal system for the waste products of its own metabolism. All of this is accomplished by the placenta, which allows the growing embryo to eat and breathe while in the mother's uterus.To get some perspective on how the placenta began, let's go back to Day 8. This hollow ball of cells moving through the uterus is the blastocyst, searching for an implantation site. Here you see its outer layer beginning to extend out and implant in the uterine lining, searching for the uterine blood vessels that would nourish it throughout the pregnancy.As it went deeper, a single layer of cells from the mother's uterine lining surrounded it, so that it would be protected from harm. On Day 9, as it grew larger and more complex, the blastocyst became an embryo. Here it's about the size of a pinhead.Also on Day 9, the outer layer of the embryo developed spaces called lacunae. The lacunae filled up with blood from the mother's uterine lining.On Day 13, small projections from the embryo's chorionic layer reached out into the uterine lining. The chorionic layer is one of the membranes that surround the embryo and help it implant.On Days 15 through 21, blood vessels began to form beneath this chorionic layer.Around Day 21, the embryo's blood stream and the mother's blood stream were in such close contact that nutrients and oxygen could cross from mother to embryo. This was how the embryo first got its food and air from the mother, and technically this is when the placenta began to function.Let's magnify this area so you can see what we're talking about. Here you see a vein and an artery from the embryo in close contact with the blood in the mother's uterine lining. Inside the blood vessels, you can also see red blood cells, which carry oxygen.The two blood streams are separated by a thin collection of tissues in the placenta called the blood barrier. This barrier permits small particles like nutrients and oxygen to pass from the mother to the embryo, (pause) and allows waste products to pass from the embryo back to the mother. The blood barrier also prevents many large or potentially harmful particles from entering the embryo's blood stream. Notice that the red blood cells do not cross from the mother's blood stream to the embryo's.You may be wondering how a mother's blood cells could be harmful to her growing baby, and why it's important to keep the two blood streams separate. If the mother's blood type is RH negative, and her embryo's blood type is RH positive, then the mother's antibodies would treat the embryo as an invading foreign organism, and try to destroy it.Now you can see why the placenta and its blood barrier are important for supplying the growing embryo with nutrition and oxygen, removing its waste products, and preventing harmful substances from getting into its blood stream.Reviewed ByReview Date: 09/16/2008Dan Sacks MD, FACOG, Obstetrics & Gynecology in Private Practice, West Palm Beach, FL.

Is Yemen a developed or developing country?
Yemen is a developing country and it's moving forward to improving its economy in the coming years.
What is a Country moving from an agricultural to an industrial economy are referred to as?
I think you mean a developing country.
What is embryo transport?
Embryo transport refers to the process of moving embryos, typically in the context of assisted reproductive technologies, from one location to another. This can involve transferring embryos created via in vitro fertilization (IVF) to a recipient's uterus or transporting them between laboratories for research or preservation. Proper handling and storage conditions are crucial to maintain embryo viability during transport. This process is essential for successful implantation and pregnancy outcomes in fertility treatments.
Was it bad cause your doc only seen a sac at 5 weeks?
Seeing only a sac at 5 weeks of pregnancy can be concerning, but it's not uncommon. At this early stage, it may be too soon to detect a developing embryo, as some pregnancies progress at different rates. It's important to follow up with your doctor for further monitoring and possibly another ultrasound to assess the situation. They can provide clarity on what to expect moving forward.
Can you get worms in your period blood?
If the "worms" are dark red and not moving, I'm guessing what you're seeing are pieces of the uterine lining which sloughs off each month. If they're moving - I have no idea what's going on!
What is the difference between fertilization and implantation?
the difference is, fertilization is when you want something to grow and you put fertalizer down (it most likely would be on grass) and implantation when you are growing something or you are moving a plant or something like that. :)
What is the word to change from worse to better?
improving enhancing developing perfecting upgrading
When do the puppies start moving in the womb?
Puppies start moving in the womb around day 45-50 of gestation. At this stage, they are developing their motor skills and strength, which allows them to start shifting and kicking inside the mother's womb.
