Systemic Ion Absorption Pathways

Systemic ion absorption pathways refer to networks of molecular mechanisms and transport processes by which ions are absorbed from the external environment (such as the intestinal lumen or renal tubule) into the bloodstream or other compartments, ensuring maintenance of electrolyte balance, cell function, and whole-body homeostasis. These pathways include various cellular transport mechanisms (active transport, co-transport, facilitated diffusion, passive diffusion, endocytosis), transcellular and paracellular routes, and involve numerous transporters and channel proteins (e.g., SGLT-1, GLUT-5, claudins, occludin, sodium/potassium pumps, aquaporins). They are essential for normal physiology and can be dysregulated in diseases such as cancer, hypertension, kidney disorders, and genetic channelopathies[1][5][6][4][9]. There is no single "systemic ion absorption pathway" molecule or receptor; it is a descriptive term for the collective physiological processes and involved proteins. For structured database purposes, this should not be treated as a canonical molecular target.
