Chloride Ion Transport Across Intestinal Wall - Biological Mechanism Explained #1404165 (License: Personal Use)

This scientific illustration depicts active chloride ion (Cl⁻) transport across the intestinal epithelium via specialized green channel proteins embedded in the blue intestine wall. The diagram distinguishes the extracellular space outside the intestine (top), the wall itself, and the luminal interior (bottom), where purple oval-shaped molecules represent other solutes or nutrients. The orange structure may indicate a regulatory protein or transporter assisting ion movement.
