Efferent Glomerulus Distal A minimum daily urine output of approximately 400 mL is re- arteriole tubule quired to remove normal amounts of metabolic end products. Glomerular Filtration Arterial blood enters the glomerulus by the afferent arteriole Afferent at the relatively high pressure of approximately 70 mm Hg. This fluid, called glomerular filtrate, contains the Proximal same components as blood except for blood cells, fats, and tubule proteins that are too large to be filtered. The glomerular filtration rate (GFR) is about 180 L/day, or 125 mL/minute. Most of this fluid is reabsorbed as the glomeru- lar filtrate travels through the tubules. Because filtration is a nonselective process, Collecting the reabsorption and secretion processes determine the com- tubule position of the urine. Once formed, urine flows into collecting tubules, which carry it to the renal pelvis, then through the ureters, bladder, and urethra for elimination from the body. Descending Blood that does not become part of the glomerular fil- limb of loop trate leaves the glomerulus through the efferent arteriole. Peritubular capillaries Tubular Reabsorption Loop of Henle The term reabsorption, in relation to renal function, indicates Figure 56–1 The nephron is the functional unit of the kidney. Increased capillary permeability occurs as part of the occurs in the proximal tubule. Thus, edema may occur acids are reabsorbed; about 80% of water, sodium, potas- with burns and trauma or allergic and inflammatory sium, chloride, and most other substances is reabsorbed. In the descending limb of the loop of Henle, water from a sequence of events in which increased is reabsorbed; in the ascending limb, sodium is reabsorbed. This is the primary mechanism for marily by the exchange of sodium ions for potassium ions edema formation in heart failure, pulmonary edema, secreted by epithelial cells of tubular walls. The remaining water and solutes are now appropri- with decreased synthesis of plasma proteins (caused ately called urine. This conserves water important in keeping fluids within the blood- needed by the body and produces more concentrated urine.
