The Amniotic Sac
Amniotic Sac is a bag made of thin- walled tissue. The amniotic sac lie within the uterine lining and is filled with a fluid, known as the amniotic fluid. The amniotic Sac is made of two membranes, called the amnion and the chorion. Chorion is the outer membrane, and it contains the amnion. The Chorion is a part of the placenta itself. On the other hand the amnion is the inner sac, and it contains the amniotic fluid. The Chorion is also often referred to as the “bubble” is the “Amniotic Bubble”. This is because of its appearance. The amniotic sac is smooth and shiny; however, it is fairly difficult to pierce and protects the foetus to a great extent.
When the amniotic sac ruptures, the fluid in the sac either trickles out or gushes out. This phenomenon is often referred to as “water breaking”. The amniotic sac grows in size throughout the period of the pregnancy. This is because the amount of the amniotic fluid in the sac keeps increasing throughout this span. This increase in the amniotic fluid takes place until the 38th week of the pregnancy. It reduces slightly before the baby is born. At the time of birth, the sac breaks and the fluid is released.
The Amniotic Fluid
The amniotic fluid is a straw colored liquid that is found in the amniotic sac. The amniotic fluid is made of several components and is responsible for protecting the foetus from any sort of injury. The amniotic fluid, in a way acts as a shock absorber and protects the foetus against any sort of jerks that the mother or the womb might be subjected to. The amniotic fluid is a little watery and allows the foetus to move freely without being bounded by the uterine walls. Apart from this, the amniotic fluid also provides buoyancy to the growing foetus.
Complications associated with the amniotic fluid
Complications might arise in the pregnancy when there is either too little or too much of amniotic fluid. In both these cases though, it has been observed that a normal delivery takes place. However, sometimes, any of these conditions may lead to limb contractures in the baby. These may also cause the clubbing of hands or feet in the baby. Worse still, these may also lead to a life threatening or fatal condition like hypoplastic lungs.
To avoid all these conditions, or to be well equipped to take action against any of these conditions, it is important that the mother undergoes an ultrasound. In fact this should be done on a regular basis. Apart from this, the amniotic fluid and the amniotic sac are today, being used to detect any sort of health related problems in the foetus.
