👉 The term "whorle" is a biological concept that refers to the middle part of a胎儿的 placenta, or uterine wall, which contains the fetal membrane and other structures. The whorle is made up of three layers of cells, each with its own function: the mesenchymal layer is responsible for supporting and protecting the developing fetus, the myoid layer provides support to the mesenchymal layer, and the endoderm (the outermost layer)
