A souffle (English: / ˈ s uː f əl /) [a] is a vascular or cardiac murmur with a blowing quality when heard on auscultation. It is particularly used to describe vascular murmurs or transmitter heart sounds which occur during pregnancy, either from the uterus and breasts of the mother, or from the fetus.
The fetal circulation is composed of the placenta, umbilical blood vessels encapsulated by the umbilical cord, heart and systemic blood vessels. A major difference between the fetal circulation and postnatal circulation is that the lungs are not used during the fetal stage resulting in the presence of shunts to move oxygenated blood and ...
The placenta also produces human placental lactogen (hPL), which stimulates maternal lipolysis and fatty acid metabolism. As a result, this conserves blood glucose for use by the fetus. It can also decrease maternal tissue sensitivity to insulin, resulting in gestational diabetes.
Vasculature of the placenta, with a chorionic artery labeled in . Chorionic (plate) vessels, also fetal surface vessels [1] are blood vessels, including both arteries and veins, that carry blood through the chorion in the fetoplacental circulation. Chorionic arteries branch off the umbilical artery, and supply the capillaries of the chorionic ...
Hippomanes arise from unconsumed and thickened nutrient fluid (histiotrophe) of the placenta, in concentric layers around the centre of allantoic calculi of tissue debris. [1] The chemical composition is different to amniotic fluid, which along with the insolubility suggests that it's not a result of a simple precipitation process, but a ...
Placenta shown with attached fetal membranes The fetal membranes surround the developing embryo and form the fetal-maternal interface . [ 3 ] The fetal membranes are derived from the trophoblast layer (outer layer of cells) of the implanting blastocyst . [ 3 ]
Image showing trophoblast differentiated into the two layers of cytotrophoblast and syncytiotrophoblast during implantation. It is the outer layer of the trophoblasts and actively invades the uterine wall, during implantation, rupturing maternal capillaries and thus establishing an interface between maternal blood and embryonic extracellular fluid, facilitating passive exchange of material ...
The form of the human placenta is generally classified as a discoid placenta. Within this, the cotyledons are the approximately 15-25 separations of the decidua basalis of the placenta, separated by placental septa. [3] Each cotyledon consists of a main stem of a chorionic villus as well as its branches and sub-branches. [3]
