Final answer:
The two cell types on the surface of the intestinal villi are absorptive epithelial cells, which uptake nutrients, and goblet cells, which secrete mucus.
Step-by-step explanation:
The two cell types found on the surface of the intestinal villi are absorptive epithelial cells and goblet cells. Absorptive epithelial cells are the most abundant and are specialized for nutrient uptake; their apical surfaces are covered with microvilli, which form a brush border that increases the surface area for absorption. Goblet cells are scattered among the absorptive cells and are responsible for the secretion of mucus, which lubricates the intestinal contents.
The two cell types found on the surface of the intestinal villi are absorptive cells and microvilli. Absorptive cells are primarily composed of the mucosal epithelium and cover each villus. They are responsible for absorbing breakdown products of carbohydrates and proteins into the bloodstream. Microvilli are cylindrical extensions of the plasma membrane of the epithelial cells in the mucosa. They greatly increase the surface area of the small intestine for absorption and are covered with enzymes that finish digesting carbohydrates and proteins.
