Placenta
Placenta is the organ that attaches itself to the uterus during the earliest stages of pregnancy. It provides blood, oxygen, and nourishment to the fetus while also allowing a way for waste to exit the baby's blood as well.

How early can you see the placenta on ultra sound?
at about 4 weeks they can sometimes see the gestation sac. by 5 weeks they can usually see the yolk sac. and by 6 weeks you can usually see a fetal pole, sometimes even a heartbeat
Which hormone is associated with the maintenance of the placenta?
There are a number of different hormones involved in pregnancy, and I will outline the main hormones and their purposes below:
- Human Chorionic Gonadotrophin - this is involved in the maintanence of the corpus luteum, which secretes progesterone and oestrogen during the first 12 weeks of pregnancy, after which the placenta takes over production of these hormones. This hormone is secreted by the chorion/placenta.
- Oestrogen - initially secreted by the corpus luteum up to 12 weeks, after which placenta takes over secretion of this hormone.Oestrogen inhibits the hormones FSH (Follicle Stimulating Hormone) and LH ( Lutenising hormone), both of which are involved in the process of ovulation in a menstruating woman. During pregnancy, menstruation must stop, and so Oestrogen inhibits these 2 hormones. It also acts on the uterus, causing growth of the uterus and increasing the sensitivity of the uterus to the hormone oxytocin which is involved in the processes of birth and lactation. It also inhibits the hormone prolactin, and thus inhibits lactation during pregnancy. However, it stimulates the development of the ductal system in the breasts in preparation for lactation after the baby has been born. Causes a softening and relaxing of the ligament of the pelvic girdle.
- Progesterone - again this is initially secreted by the corpus luteum, and later by the placenta. It stimulates the development of milk glands, and also inhibits the secretion of prolactin ( in order to stop lactation) and also inhibits FSH and LH. It stimulates growth and glandular activity of the uterus. It is essential for successful implantation and maintainence of the endometrium, stimulates endometrial glands to secrete nutrients taken up by the developing embryo and slightl supresses the mother's immune system so the foetus is not rejected. As a steroid hormone, it is transferred to the fetus and used by the fetus for production of fetal hormones by the fetal adrenals. It also quitens muscular contractions of the uterus to prevent premature expulsion of the fetus, causes mammary glands to develop and enhances their ability to produce milk.
- Human placental lactogen - hormone made in the placenta which gives foetus priority over maternal glucose and fatty acids. Also known as Human Chorionic Somatomammotrophin.
- Prolactin - secreted by the maternal anterior lobe of pituitary gland, it is essential for expression of oestrogen and progesterone on the mammary glands. Having said that, oestrogen (and progesterone) inhibits lactation until birth. When levels of Oestrogen and Progesterone then decrease after birth, prolactin can exert its effects fully and lactation can take place.
- Relaxin - Causes the relaxation of ligaments, softens the cervix and inhibits muscle contractions.
The placenta provides your developing baby with a supply of blood, oxygen, and nutrients vital to a healthy baby! The placenta is fully developed by your 18th week of pregnancy. The placenta also carries waste including carbon dioxide away from your baby. The quality of function of your placenta is dependent upon how healthy you are, this is why it is important to keep your blood and oxygen as clean as possible especially during pregnancy (which is why you should not drink or smoke during pregnancy). The placenta keeps harmful materials away from your baby including infections but the body does not always recognize these harmful substances which is another reason you should not drink,smoke or take drugs during pregnancy.
What is the risk of placenta acreeta after c sections?
Extremely dangerous. I miracously survived one in o6 along w my son. You should have a team of specialists present at birth. Ready to repair any organ that it may have grown into and possibly you might need blood transfusions for hemoraging complications so look into family donating blood.

What is the consequences for the umbilical cord not to have 3 vessel cords?
The feotus will get blood/nutrients less easily from mother as less vessels means a smaller flow of the babies vital nutrition. The extent of this however, depends on the stage of pregnancy, missing vessel and personal case - see doctor to seek advice

What happens if placenta is down at the time of 5 months pregnancy?
This condition is called placenta previa and has various grades, from 1 to 4.
It depends how far down, if right Dow, cwentrally over the cervix it will probably stay there and the mother wil;l have to be jhospitalised for the latter part of her pregnancy as this is potentially fatal to mother or baby and if she starts bleeding will need an immediate C-section. If it is height#er it Amy move out of the way.
What impact does gestational diabetes have on the placenta?
Gestational diabetes affects the mother only after the baby's body has been formed. So no birth defects, but babies may develop low blood glucose and breathing difficulty.
The placenta supports the baby as it grows. Hormones from the placenta help the baby develop. But these hormones also block the action of the mother's insulin in her body. This problem is called insulin resistance. Insulin resistance makes it hard for the mother's body to use insulin. She may need up to three times as much insulin.
it increases the risk for post partum hemorrhage and infection The person who delivers the placenta should ensure it is complete so this doesn't happen. an operation may be required to remove the remaining placenta.
What is the value of a 2005 dime that is normal front side and blank on the back?
Without seeing the coin it's difficult to say what you have. If the reverse side is smooth and the coin is lighter than a normal dime, it's almost a dead cert that someone with too much time on their hands filed it down. For one thing, if it's completely smooth it couldn't have come out of a coin press that way because the blank should have a raised rim on both sides, regardless. In this case it's a damaged coin worth nothing more than face value.
OTOH, if the coin has some evidence of a design and/or shows the inside copper core, you could have a so-called lamination error that occurs when part or all of the outer cladding fails to bond to the core. These are true mint errors and would be worth a few dollars to an error collector.
Some lip balms and cosmetics may contain ingredients derived from animal sources, including placenta or placental extracts, although this is not common. Most mainstream chapsticks do not list placenta as an ingredient. It's always best to check the ingredient list if you're concerned about specific components. Additionally, many brands now offer vegan options that do not contain any animal-derived ingredients.
What is the role of the uterus in the development of the fetus and the placenta?
The uterus is where the fetus develops and the placenta connects the uterus to the fetus.
