The happiest moment in the life of a woman is the moment of her first pregnancy. The fetus is inside her uterus surrounded by a thin membrane which is amniotic sac and inside is the amniotic fluid in which that the unborn baby float in it and moves easily. This amniotic fluid is a yellowish liquid and like water, it contains fetal cells and about 98% of water, 2% salts, carbohydrates, proteins, peptides, lipid and electrolyte enzymes (Penn Medicine, 2013). This fluid filled the extracelomic cavity and then the amniotic space become identified and easily to be seen within days of implantation. The amniotic fluid is made from mother's body, so that the water from amniotic fluid is coming from maternal plasma cells that moves through the fetal membranes, this movement could be during after vessels development so that the water and salts will moves from maternal plasma cells across the placenta to fetus and then to the amniotic fluid.
In the early period of embryo the volume of amniotic fluid is about 25 ml at 10 weeks and it increase to about 400 ml at 20 weeks, in this period of time the amniotic fluid composition is similar to fetal plasma (Mark, William & Michael, 2005). Also at this period of time the amniotic fluid serve as a physiological buffer, because it pass across non keratinized fetal skin and the amnion surface, placenta and umbilical cord all are permeable to water and solutes. By the week of gestation which is about week 8, the kidney of fetus start to function and the fetus start to make his own contribution to amniotic fluid and this can be done by swallowing and urinating into the amniotic fluid, so now amniotic fluid is mostly achieved by excretion of fetal urine. Specifically, we can say that fetu...

- ... This inhibitor may serve as the primary defence against invading microbes, mainly gram-negative bacteria. The sensitivity to phosphate ions is what makes this bacterial inhibitor unique to other inhibitor systems. The peptide compnent of the inhibitor also makes the system special by its molecular size being similar to that of hormones and antibiotics. • Growth and development of fetal lungs: There must be enough amniotic fluid present to prevent lung compression, normal fetal breathing movements and the volume of fluid within the developing airways....

- Oligohydramnios Oligohydramnios is a condition in which there is not enough fluid in the sac (amniotic sac) that surrounds your unborn baby (fetus). The amniotic sac in the uterus contains fluid (amniotic fluid) that: • Protects your baby from injury (trauma) and infections. • Helps your baby move freely inside the uterus. • Helps your baby 's lungs, kidneys, and digestive system develop. This condition occurs before birth (prenatal condition), and it can interfere with your baby’s normal prenatal growth and development.... [tags: Pregnancy, Fetus, Childbirth, Obstetrics]

- Introduction The mechanism of the differentiation of stem cells (SCs) into smooth muscle cells (SMCs) is not yet fully understood, although recent research in this area has made significant strides. In previous studies, human embryonic mesenchymal stem cells (hEMSCs) were shown to differentiate by induction with transforming growth factor beta (TGF-Β) through Smad and serum response factor (SRF), p38 mitogen-activated protein kinase (p38 MAPK), and PI3k Phosphoinositide 3-kinase (PI3k).3 Human amniotic stem cell derived smooth muscle cells do not show continuous differentiation and are functionally different as compared to embryonically derived cells.2 This may be influenced by differe...

- The volume flow rate of a fluid is the amount of fluid that passes a point per second. It is dependent on a number of variables. These variables include the dimensions of the object that the fluid is flowing through, and the amount of force that is applied to it. The pressure that water in a pipe system is under is calculated using the following equation: P=F/A Where P is the pressure, F is the force that is being applied to the water, and A is the area that the water is in. The force in the previous equation can be calculated using Newton’s Second Law of Motion, F=ma (University of Tennessee, 2014).... [tags: Fluid dynamics, Viscosity, Fluid]

- THE FOUNDER OF MODERN FLUID DYNAMICS: LUDWIG PRANTDL A fluid is defined as a substance that does not have any determined shape and is deformed continuously by a shear force, thus it can be said that fluid mechanics is considered as a part of physics which is concerning about gases, liquids and plasmas, in the other words, no solid phases. Modern fluid mechanics is based on Continuum Hypothesis. This hypothesis assumes that a matter is continuous, hence while a matter is examined, atomic structure is not regarded- because if a matter is analyzed at a microscopic scale, the matter will be observed as discrete- and macroscopic scale is preferred instead of microscopic scale. Fluid mecha... [tags: fluid mechanics, boundary layer, adhesion]

- Morality of Amniotic Tissue Research It seems that there is always new groundbreaking technology introduced into society. Our hope is to find some magical chemical that will cure all diseases or cancer. Imagine that a miracle substance was found but came, at what some may think is to high a price. Amniotic tissue is remarkable in its healing abilities, however, many think it is wrong to utilize the tissue since it is taken from aborted fetuses and embryos. Are the research processes of fetal tissue in direct conflict with our moral values, or is it negligent for us not to do research that might lead to cures for Alzheimer’s, diabetes, and Parkinson’s disease....

- During a severe blizzard, a 25 year-old Caucasian woman named Linda arrives at Thomas Jefferson University Hospital in Philadelphia, PA after being in labor for over thirty hours at home. Being only 28 weeks pregnant, she was hoping that her contractions would be able to be stopped. Unfortunately the delivery was not able to be interrupted and she delivered a premature baby boy named David at 28 weeks gestation; weighing only 1400 grams. Due to the difficult labor, and baby David being a Frank breech, David was delivered via caesarian section.... [tags: premature babies, breathing, health]

- Archimedes and Fluid Mechanics Fluid mechanics studies the behaviour of liquids and gases at rest or in the motion. It can be divided into 3 different areas; fluid statics research on fluids at rest, fluid kinematics that investigates fluids in motion, and fluid dynamics that analyses the effect of forces on fluid motion. The second and especially the third areas are greatly used on both solved and partly solved problems. The study of fluid mechanics is significant to engineers; because the main interest of engineers is to solve industrial problems in the applications of fluid mechanics....

- Your car will rely on many things especially fluids to keep all the mechanical parts well lubricated and working without using much heat on high-friction functions. Transmission fluid is one of the most important fluids in the car. Significance The transmission system uses clutch, actuating shafts and all the gear connections. Each engine gear will have a limit, which is defined by the red line that is always defined by the revolutions per minute. When the gear of your vehicle reaches the limit, it has to stop spinning and let another gear power the vehicle.... [tags: Automobiles]
