Retroperitoneal

Behind the peritoneum

Renal pelvis

Funnel-shaped cavity in kidney that channels urine to ureter

Renal medulla

Inner part of the kidney

Nephrons

Functional unit of kidney made of renal corpuscle and renal tubule

Urine

Wastes and excess water/electrolytes excreted by kidneys through ureters, bladder, and urethra

Afferent arteriole

Vessel that carries blood to the glomerulus

Nephron

Functional unit of kidney consisting of renal corpuscle and renal tubule

Renal corpuscle

Part of nephron made of glomerulus and glomerular capsule

Renal tubule

Part of nephron extending from corpuscle to collecting duct

Glomerulus

Capillary tuft that filters blood in nephron

Glomerular capsule

Double-walled enclosure around glomerulus (Bowman’s capsule)

Efferent arteriole

Vessel that carries blood away from glomerulus

Peritubular capillary system

Capillaries around renal tubule for reabsorption and secretion

Juxtaglomerular apparatus

Cells that regulate renin and monitor tubular fluid

Glomerular filtration

Filtration of plasma in glomerulus

Glomerular filtrate

Water and solutes filtered from blood

Tubular reabsorption

Movement of substances from tubule back into blood

Tubular secretion

Movement of substances from blood into tubule for excretion

Filtration

Movement of material through membrane due to pressure

Net filtration pressure

Force driving filtration in kidneys

Renin

Enzyme that helps regulate blood pressure and volume

Urea

Waste from amino acid breakdown

Uric acid

Waste from nucleic acid breakdown

Ureter

Tube carrying urine from kidney to bladder

Micturition
