What is the function of the nephron?
Extract CO2 from blood and clean water to make urine.
Filter blood and send blood to ureter to make urine.
Filter blood and send blood to bladder to make urine.
Filter water and extract waste which forms urine.
Filter blood and extract waste which forms urine.
What are the three stages, and in order, of urine formation?
Tubular reabsorption, glomerular filtration, tubular secretion.
Glomerular filtration, tubular reabsorption, tubular secretion.
Tubular secretion. tubular reabsorption, glomerular filtration.
Glomerular reabsorption. tubular reabsorption, glomerular filtration.
Glomerular reabsorption, tubular filtration. tubular reabsorption,
What is the purpose of glomerular filtration?
Re-incorporate substances back into the bloodstream
Waste ions and hydrogen ions reabsorbed from the capillaries into the renal tubule.
Different kinds of waste are filtered from glomerulus and into bowman's capsule.
Substances that may have been filtered and are not considered wastes
Moving urine from tubule into collecting duct.
What is the purpose of tubular reabsorption?
Re-incorporate substances back into the bloodstream
Waste ions and hydrogen ions reabsorbed from the capillaries into the renal tubule.
Different kinds of waste are filtered from glomerulus and into bowman's capsule.
Movement of substances from capillaries and filtration of waste into bowman's capsule.
Moving urine from tubule into collecting duct.
What is the purpose of tubular secretion?
Re-incorporate substances back into the bloodstream
Waste ions and hydrogen ions reabsorbed from the capillaries into the renal tubule.
Different kinds of waste are filtered from glomerulus and into bowman's capsule.

Moving urine from renal pelvis into ureter.
A patient was suffering from a disease which affected the bladder. What potential problems could this cause?
Formation of urine.
Build-up/accumulation of urine in kidney.
Storage of urine.
Removal of urine from body.
Movement of urine from nephrons (wastes removed) and into ureter.
A patient was suffering from a disease which affected the renal pelvis. What potential problems could this cause?
Formation of urine.

Formation of urine.
Build-up/accumulation of urine in kidney.
Storage of urine.
Removal of urine from body.
Movement of urine from nephrons (wastes removed) and into ureter.
A patient was suffering from a disease which affected the urethra. What potential problems could this cause?
Formation of urine.
Build-up/accumulation of urine in kidney.
Storage of urine.
Removal of urine from body.
Movement of urine from nephrons (wastes removed) and into ureter.
A patient was told to eat foods low in salt, what affect could salts already had on his body?
Foods high in salt cause water to be KEPT inside the body which means there are a build up of liquids.
Foods high in salt cause water to be REMOVED QUICKLY inside the body which means there is a removal of too much liquids.
The kidneys don't have any direct function with the level of salt.
The kidneys would immediately stop functioning
The process or urine formation would take longer.
