5 True/False Questions
Submucosa → The inner lining of the digestive tract and consists of its own three layers: epithelium, lamina propria: loose CT, and muscularis mucosae: a thin smooth muscle layer.
Excretion → Removal of waste products (feces) from body.
Absorption → Removal of waste products (feces) from body.
Muscularis Mucosae → Deep to the lamina propria, a thin layer of smooth muscle cells, and muscle contraction causes movement of the mucosa.
Epithelial Cells of Gastric Glands- Endocrine cells → G cells and Stem cells.
