Production of urine to modify plasma makeup is the result of ________

The blood filtrate is captured in the lumen of Bowman's capsule, which surrounds the glomerulus. The glomerulus is a network of capillaries where blood is filtered, and the filtrate (containing water, ions, and small molecules) passes into Bowman's capsule before moving into the renal tubules for further processing.

The production of urine to modify plasmamakeup is the result of glomerular filtration, tubular absorption, and secretion. Glomerular filtration is the first step of making urine; a process where the kidney filter excess fluid and water products out of the blood in the urine collecting tubules of the kidney, to be eliminated in the body. Tubular reabsorption involves the removal of water and solutes from the tubular fluid which is returned to the circulating blood; while secretion involves the removal of wastes from the body into the bladder, then out through the urethra.

Afferent arteriole supply blood to the kidney from the renal artery while efferent arterioles are blood vessels through which blood exits the glomerulus.

Distal tubule is responsible for regulating extracellular fluid volume and electrolyte balance while the proximal tubule is responsible for reabsorbing macromolecules, filtered sodium ions, and low molecular weight proteins.

The efferent arteriole then forms a second capillary network around the tubule, called theperitubular capillaries. For juxtamedullary nephrons, the portion of the capillary that follows the loop of Henle deep into the medulla is called the vasa recta.
