And so what that means is the entire lymphatic system is also made from the mesoderm. And the lymphatic system, if you recall, not only plays a role in immunity, in protecting our body from pathogenic infections, but it also plays a role in basically removing that extra fluid that is found in the interstitial space between our cells in the body. Now recall that the adrenal modula, the inner portion of that adrenal gland is formed from the exoderm. But the mesoderm forms the adrenal cortex, the outer portion of those adrenal glands. Now it's the ectoderm that forms the outer portion of the skin but the inner portion of the skin is formed from the macederm. So the dermis, the inner portion is formed from the mesoderm.
