Amniotic fluid Amniotic fluid is the liquid that surrounds the fetus after the first few weeks of gestation and is contained within the amniotic cavity. It surrounds the growing fetus, protecting it form external pressure. The fluid is initially secreted from the amnion and is later supplemented by urine from fetal kidneys. Some fluid is swallowed by the fetus and absorbed by the fetal intestine. It has a composition similar to blood plasma, and is initially produced by transport of fluid across the amniotic membrane itself. From week 16 onwards, fetal urine makes an important contribution to the amniotic fluid. If the fetus excretes no urine, the volume of amniotic fluid will be low, and leads to a condition known as oligohydramnios. …show more content…
Once the GIT was collected, the fetuses undergoing normal gestation had a relative weight of the small intestine to increase by 80%, while the fetuses that did not swallow had a reduction in body weight by 43%. The results clearly show that amniotic fluid is paramount to the development of the GIT. (Sangild, 2003) • Trauma protection: The watery environment acts as a shock absorber, attenuating any external force. • Temperature regulation Oligohydramnios Oligohydramnios is the aberrant condition, which occurs in 4% of pregnancies, where there is a low level of amniotic fluid, causing the amniotic cavity to be too small. It can occur in any trimester, although it is more common to occur during the third trimester. Oligohydramnios accompanies a broad range of reproductive disorders including fetal anomalies, such as impaired growth and development, functional anomaly to mother and placenta. The most common cause of oligohydramnios is the rupture of the amniotic sac. Causes of Oligohydramnios: The five main causes of oligohydramnios are: 1. Fetal causes: The kidneys develop between weeks 5 and 7 of fetal gestation, and urine production commences at week 14. When kidneys fail to develop properly, renal agenesis, less or no fetal urine is produced, which is the main contributor for amniotic fluid synthesis; hence, a low volume of amniotic fluid is produced. 57% of oligohydramnios cases are due to
pregnancy. This serious complication results in a miscarriage and can cause death of the mother.
To observe the anatomy and physiology of the fetal pig through dissection, the procedures for Labs 22-26 of the Biology 1107 Principles of Biology Laboratory Manual, 2017 were followed directly. This includes all materials and steps included (Lombard, Terry, Malinoski, 2017, Pages
Due to the fact that the fetal pig and the human being’s anatomy are extremely similar, with the exception of a few minor parts, the fetal pig will be a precise tool in learning about the anatomy of a human.
protein produced by the yolk sac and the liver during the fetal period. Research was done
Purpose: The purpose of this outline is to act as a guide and accompaniment to the Fetal Fibronectin Power Point as well as an aid for the Case Study learning activity.
Anything a mother consumes will affect her baby’s health, either positively or negatively. After the sperm enters into the egg, instantly, the baby begins to grow inside of the placenta, which is inside of the mothers’ uterus. “The placenta has been described as a pancake-shaped organ that attaches to the inside of the uterus and is connected to the fetus by the umbilical cord.” As the placenta produces the hormones for the baby, it also supplies the blood to the fetus from the mother. The most important element that allows the fetus to grow is the umbilical cord. The umbilical cord is composed of three blood vessels that attach to the placenta and the fetus. All of these components help the baby’s growth, but the amniotic sac, which is composed of amniotic fluid, helps protect the fetus. The amniotic fluid helps the baby maintain a regular body temperature that
The placenta is an organ that develops and attaches to the uterus during pregnancy; it is connected to the fetus by the umbilical cord. This is
On today’s evaluation, she is 19 weeks and the fetal measurements overall are concordant. The long bone measurements are within one week of her dates. The amniotic fluid volume is normal, and the cervix is long and closed. A complete fetal anatomical survey was performed and a significant amount of ventriculomegaly/hydrocephalous was identified but no other major malformations were noted at this time, though due to the
By dates, the patient is 35 5/7 weeks and the measurements are concordant. The amniotic fluid volume is normal. The fetus is in cephalic presentation. The BPP and Doppler studies are reassuring. A complete fetal anatomical survey was performed and no major malformations were noted at this time within the resolution of the ultrasound equipment other than the fetal abdomen. There is a cystic structure seen in the fetal abdomen that is about 3 cm in diameter with some echolucency surrounding this. It is below the kidney but above the fetal bladder as identified in your office.
This particular case study involves a 29 year old obstetric patient who presented to the labor and delivery unit at 33 weeks gestation with complaints of abdominal pain for the past three days that had become more severe and absence of fetal movement noted since the previous evening. Her obstetric history revealed she has one living child and has had one previous miscarriage at ten weeks
Most of the birth defects occur during the first three months of pregnancy when the baby’s organs
On ultrasound there is a live fetus in breech presentation. Fetal biometry is consistent with menstrual dates. A detailed anatomic survey was unremarkable but slightly suboptimal
On ultrasound there is a live fetus in cephalic presentation. Fetal biometry is consistent with dates. A detailed anatomic survey was fairly unremarkable although slightly suboptimal due to late gestational age. There were no gross abnormalities seen. The placenta is anterior. Amniotic fluid was 8.3 cm. Umbilical artery Doppler was within normal limits.
by sampling the amniotic fluid, which contains cells and chemicals which are fetal in origin.”(4) This
The device consists of a clear plastic bag filled with synthetic amniotic fluid, much like the inside of a mothers womb. A machine outside the bag is attached to the umbilical cord to function like a placenta, providing nutrition and oxygen to the blood and removing carbon dioxide. This is detrimental to the development of a fetus, as everything needs to be re-created in such a way that there is no difference in the natural and artificial methods. This ensures that the development and maturation of the fetus.
