A journal is a scholarly periodical aimed at specialists and researchers. Articles are generally written by experts in the subject, using more technical language. They contain original research, conclusions based on data, footnotes or endnotes, and often an abstract or bibliography.
When aldosterone is absent, Na+ reabsorption in the nephron is greatly reduced, and as 30-40g of sodium can be lost in the urine daily. The answer is decreased. Site: Anatomy and Physiology Eighth Edition by Seeley Stephens Tate.
Regulation of Na + Reabsorption. The principal regulator of Na + reabsorption is the steroid hormone aldosterone, which is produced in the zona glomerulosa of the adrenal cortex. Aldosterone, like all steroid hormones, works as a transcription factor to alter gene expression in cells.he figure provides an overview of Na + reabsorption along the nephron. In different segments of the renal tubule, there are different proteins (co-transporters, counter-transporters, or channels) on the apical surface of tubule cells that mediate Na + reabsorption.
