👉 Endoderm is a type of epithelial tissue that forms the outermost layer of the digestive system and helps to protect the body by providing protection against external pathogens. It's also involved in the digestion process by secreting enzymes and acids, which help break down food into smaller pieces for easier absorption. Endoderm cells can be found in the lining of the stomach, small intestine, and other organs that are not directly exposed to digestive processes.
