WebA germ layer is a layer of cells that will go on to form one of our organizational tubes. Our anatomy can really be boiled down to an inner tube (our digestive tract), and a series of tubes that wrap around it. The three germ layers that will translate into these tubes are the ectoderm, the mesoderm, and the endoderm. Web7. A coelom is a fluid-filled body cavity that is lined by mesoderm tissue. The two germ tissue layers key to defining a true coelom are the mesoderm and the endoderm. 8. The ecdysozoans and lophotrochozoans are triploblasts. This relates to the presence or absence of a coelom because triploblasts possess a true coelom, while diploblasts do not. 9. bipee company
