In June, USA TODAY highlighted the flow of marijuana from Colorado into small towns across Nebraska: felony drug arrests in Chappell, Neb., just 7 miles north of the Colorado border have skyrocketed 400% in three years.
Intestinal Absorptive Cells. Absorptive cells, or enterocytes, are the predominant epithelial cell type lining the lumen of the small intestine and colon. These cells are specialized for absorption of nutrients across the apical plasma membrane and export of these same nutrients across the basal plasma membrane.
The small intestine has a lining with many tiny, finger-like projections called villi. The villi increase the surface area of the intestinal lining so more nutrients can be absorbed. Each villus has capillaries inside it for absorption. See pictures here: http://images.search.yahoo.com/search/im...
