Define deamination
Removal of an amino group from an organic compound
Define urea
Nitrogen waste formed from two molecules of ammonia and one molecule of carbon dioxide
Define Uris acid
A waste product formed from the breakdown of nuclei acids
Define ureter
A tube that conducts urine from the kidney to the bladder
Define urethra
The tube that carries urine from the bladder to the exterior of the body
Define cortex
The outer layer of the kidney
Define medulla
The area insider of the cortex
Define renal pelvis
The hollow area where the kidney joins the ureter
Define nephron
A functional unit of the kidney
Define afferent arteriole
A small branch of the renal artery that carries blood to the glomerulus
Define glomerulus
The high pressure capillary bed that is the site of filtration
Define efferent arteriole
A small branch of the renal artery that carries blood away from the glomerulus to the peritubular capillaries
Define peritubular capillary
A member of the network of small blood vessels that surround the tubule of the nephron
Define Bowman’s capsule
The cup like structure that surrounds the glomerulus
Define proximal tubule
The section of the nephron joining the Bowman’s capsule with the loop of henle
Define loop of henle
The section of the tubule that carries filtrate from the proximal tubule to the distal tubule
Define distal tubule
Conducts. Urine from the loop of henle to the collecting duct
Define collecting duct
A tube that carries urine from nephrons to the renal pelvis
Define threshold level
The maximum amount of a substance that can be moved across the nephron
Define interstitial fluid
The fluid that surrounds the body cells
