Document Summary

If you drink a lot of water, more water will be excreted: maintain proper osmolality of body fluids, primarily through regulating h2o balance, regulate the quantity and concentration of most ecf ions, na+, hco3. , glucose: maintain proper plasma volume, help maintain proper acid base balance in the body, excreting (eliminating) the end products (wastes) of bodily metabolism, excreting many foreign compounds, producing erythropoietin, producing renin. Urine is stored in the bladder and periodically emptied to the exterior through the urethra: the kidney consists of an outer, granular-appearing renal cortex and an inner, striated- appearing renal medulla. The renal pelvis at the medial inner core of the kidney collects urine after it is formed. Phs3342: each kidney has a million nephrons. The two types of these microscopic functional units are shown here, greatly exaggerated, in a medullary renal pyramid capped by a section of renal cortex. 1. 2 renal vasculature (circulatory pathway through the kidney)
