Chapter 12.1 Waste Excretion & Internal Equilibrium. Flashcards
Nitrogen waste formed from two molecules of ammonia and one molecule of carbon dioxide.
Urea.
Removal of an amino acid group from an organic compound.
Deamination.
A waste product formed from the breakdown of nucleic acids.
Uric Acid.
A tube that conducts urine from the kidney to the bladder.
Ureter.
The tube that carries urine from the bladder to the exterior of the body.
Urethra.
The outer layer of the kidney.
Cortex.
The area inside of the cortex.
Medulla.
The hollow area where the kidney joins the ureter.
Renal Pelvis.
A functional unit of the kidney.
Nephron.
A small branch of the renal artery that carries blood to the glomerulus.
Afferent Arteriole.
The high-pressure capillary bed that is the site of filtration.
Glomerulus.
A small branch of the renal artery that carries blood away from the glomerulus to the peritubular capillaries.
Efficient Arteriole.
A member of the network of small blood vessels that surround the tubule of the nephron.
Peritubular Capillary.
The cup like structure that surrounds the glomerulus.
Bowman’s Capsule.
The section of the nephron joining the Bowman’s capsule with the loop of Henle.
Proximal Tubule.
The section if the tubule that carries filtrate from the proximal tubule to the distal tubule.
Loop of Henle.
Conducts urine from the loop of Henle to the collecting duct.
Distal Tubule.
A tube that carries urine from nephrons to the renal pelvis.
Collecting Duct.
The maximum amount of substance that can be moved across the nephron.
Threshold Level.
The fluid that surrounds the body cells.
Interstitial Fluid.
