It absorbs fats and fatty acids apically, converts them to chylomicra, and releases the chylomicra into the space between adjacent enterocytes. It absorbs immunoglobulins apically and releases them from its lateral walls into the space between adjacent enterocytes. Hair cells of the organ of Corti. Epithelial cells of the oviduct.
