Urinary Flashcards
Micturition/urination
Process of eliminating urine
How does urinary system stabilize blood pH
Controls loss of H+ and bicarbonate
Which ribs are the kidneys found near
11th and 12th
“Barely protected”
Function of renal lobule
Produce urine
When is the waste in the urinary tract called urine
When it reaches renal pelvis
After it passes minor calyx
Basic unit of a kidney
Nephron
Function of nephron
Produce urine
Cortical nephrons
Nephrons that have loop of henles mostly in the renal cortex
What is a juxtamedullary nephron
Nepohrons that have loops that extend mostly into renal pyramids
Where do nephrons start
Renal corpuscle
Function of glomerulus
Filters fluid and solutes from blood into capsule
Filtrate description
Protein and cell free solution
Renal corpuscle is for production of filtrate true/false
True
Proximal convoluted tubule function
For water & solute reabsorption
What substances are secreted into filtrate by tubule system
Ions, acids, drugs, & toxins
Where does tubule system release secretions into filtrate via hormones
Distal convoluted tubule
Most common nephrons in the kidneys
Cortical nephrons
Podocytes
Cells in glomerulus capsule that act as filtration slits
Filtration slits
Narrow gaps between adjacent pedocytes
Juxtaglomerular complex
Structure containing macula densa and juxtaglomerular cells
Macula densa
Cells that line distal convoluted tubule
Function of mesangual cells
Control diameter and rate of capillary blood flow,
Which tube is important solutes reabsorbed from filtrate
Proximal convoluted tubule
Organc nitrogenous waste products
Urea, creatinine, and uric acid, ammonia
What causes fatal dehydration from urinary system
Failure to concentrate filtrate in glomerular filtration
Where does active secretion occur in nephron
Distal convoluted tubule
