Describe the functions performed by the placenta for the developing embryo, and in each case, explain the mechanism that allows it to perform such function.
Placental tissue may consume as much as 80% of the glucose that moves from parental circulation into the intervillous space. How does placental consumption of glucose impact the glucose concentration gradient between the intervillous space and parental circulation? In other words, does the intervillous space or the parental circulation contain a higher concentration of glucose?
define organogenesis and indicate the important roles of the three primary germ layers in this process. what will develop from these three layers?
