Everybody knows, fetal live in amniotic fluid, amniotic fluid is right fetal for have very main effect, amniotic fluid can is fetal provide older territory, let fetal do proper breathing motion and limbs activity, prevent deformation of articulatory and fixed, limbs and fetal limbs adhesion, return the function that can balance outside pressure, lessen the impact of outside force apparently, protection is fetal.
The first speculation, the two opposing principles in nature is theoretical
Of amniotic fluid " sheep " with yin and yang " in relief " unisonant, representing human life only then cannot leave this world, this world also means the beginning of life, the genetic ground of life of be pregnant with, but why to cry " in relief water " ? So the first speculation has a place not quite rely on chart
The 2nd speculation, alimentary meaning
Amniotic fluid is the important part that keeps fetal life, it is for protection fetal and of existence, sheep and raising is homophonic, raising is to point to raise, also have give birth to the import that raises a child, amniotic fluid is nutrient child, amniotic fluid also should be called " raise water " , simplify ceaselessly through people, made amniotic fluid namely.
The 3rd speculation, basis the animal is conjectural
Amnion is person and certain vertebrate, reptile kind, avian afterbirth most the film of lining, this kind of film is particularly remarkable in ovine embryo and get a name, reason is wrapped with amnion general term by fetal outside film, the liquid in bursa of the amnion inside uterine antrum, protection is fetal do not get outside shock, also with amniotic fluid general term. This view still relies on chart quite!
The formation of amniotic fluid: ? The origin of amniotic fluid of? of awl of of ⒂ of of Mou Huang of of straightforward advice ザ also each are not identical. Be in gravid the first in March period, after amniotic fluid basically comes from embryonic serous composition; , begin mature growth as embryonic organ, path of bowel of the uric fluid with other fetal such as, respiratory system, stomach, umbilical, placental surface is waited a moment, also became the source of amniotic fluid. The composition: of amniotic fluid? Qiong some evil spirit?8% is water, have a few inorganic salt additionally kind, organic matter is hormonal with desquamation fetal cell. The amount of amniotic fluid, meet generally speaking as be pregnant of Zhou Shu increase and grow in quantity, in 20 weeks when, average it is 500 milliliter; went to 28 weeks or so, can increase 700 milliliter; to be in 32 ～ 36 Zhou Shi is most, make an appointment with; of milliliter of 1 500 of 1 000 ～ ever since drop off.
Accordingly, clinical going up is with 300 ～ 2 000 milliliter is normal limits, exceeded this limits to call " amniotic fluid crosses much disease " , this mark criterion calls short of " amniotic fluid crosses little disease " , these two kinds of situations need special attention.
The importance: of amniotic fluid? Qiong steals? of of Ma of Na Jin of of apricot ザ its importance is as follows: 1. Can serve as the index that evaluates fetal health and sexual distinction. 2. Have lubricant effect, make produce childbirth too won't dry. 3. Form water bag, neck of palace of the two pairs when be being produced and produce the function that has bate dilate, reduce the harm to the mother's body. . .
Those who thank you watch, pay close attention to me: Understand more Yo little knowledge!
