Urinary system HESI

What are the functions of the kidneys?

Excrete waste, regulate blood pressure & produce erythropoietin, renin & urine

Which structure transports urine from the kidney to the bladder?

Ureter

Bladder

Sac-like structure that stores urine

The urethra conveys urine from the

Bladder to the exterior

What is the functional unit of the kidney?

Nephron

Convoluted tubule

Tubelike structure that empties urine into the collecting duct

Glomerulus

A tuft of capillaries across which filtration of blood occurs in the nephron

Where does reabsorption, diffusion and secretion occur?

Convoluted tubules

Bowman's capsule

Cup-like structure that contains the glomerulus

Where does the glomerulus receive blood?

Renal artery

Loop of Henle (Nephron loop)

Creates concentration gradient for water reabsorption

How does solute move across the glomerular basement membrane?

Diffusion

Filtration

Blood pressure drives fluid & solutes through the glomerular capillary into Bowman's space

Kidneys capillary system

Glomerular, vasa recta & peritubular

What is a potential site of ureteral stones?

3 points of ureteric constrictions

Proximal convoluted tubule

Reabsorbs sodium, glucose, water, ions & nutrients; removes toxins

Describe the transportation of glomerular filtrate

Bowman's capsule, proximal convoluted tubule, loop of Henle, distal convoluted tubule, collecting duct, renal pelvis, ureter
