| 2 kidneys; 2 ureters; 1 urinary bladder; 1 urethra | The urinary system consists of: |
| A failure to completely or normally void urine, may be due to an obstruction in the urethra or neck of the urinary bladder | Urinary retention |
| 1. renal capsule (deep) 2. adipose tissue (intermediate) 3. renal fascia (superficial) | Layers of the tissue that surrounds the kidneys (deep to superficial) |
| 1. renal cortex (superficial) 2. renal medulla (deep) | A frontal section through the kidneys reveals two distinct regions: |
| Renal medulla: deep; darker reddish-brown; inner region; contains pyramids renal cortex: superficial; light-red area; smooth-textured | Describe the renal medulla and cortex: |
| 1. 1/2 of each adjacent renal column 2. renal pyramid 3. over-lying area of the renal cortex | The renal lobe |
| Sympathetic division of the ANS | The renal nerves are part of the |
| 1200mL/per minute | In adults, the renal blood flow to both kidneys is about: |
| R.S.I.A.I.A.G.E.P.I.A.I.R. | Blood supply of the kidneys: |
| 1. nephron 2. collecting duct 3. papillary duct 4. minor calyx & major calyx 5. renal pelvis 6. ureter 7. urinary bladder 8. urethra | Path of urine drainage: |
| Functional units of the kidneys | NEPHRONS |
| 1. renal corpuscle 2. renal tubule | Each nephron consist of: |
| 1. glomerulus 2. glomerular (bowman's) capsule | The renal corpuscle consists of: |
| 1. PCT 2. LOH 3. DCT | The renal tubule consists of: |
| 1 million | The kidneys has about..........nephrons |
| Cortical | About 80-85% of the nephrons are: |
| Juxtamedullary | About 15-20% of the nephrons are: |
| 1. renal corpuscles 2. loops of henle length 3. penetration into the renal medulla 4. supplies by peritubular capillaries or vasa recta | Differences between the cortical & juxtamedullary nephrons: |
| Modified simple squamous epithelial cells (podocytes) | The visceral layer of the glomerular capsule consists of: |
| Simple squamous epithelium | The parietal layer of the glomerular capsule consists of: |
| Capsular (bowman's) space- the space between the 2 layers of the glomerular capsule | Fluid filtered in the glomerulus enters the: |
| Simple cuboidal with prominent brush borders of microvilli | Cells of the PCT are: |
| Simple squamous epithelium | The descending and thin ascending limb of the LOH are composed of: |
| Simple cuboidal to low columnar epithelium | The thick ascending limb of the LOH is composed of: |
| Cells of the final portion of the ascending limb of the LOH that makes contact with the afferent arteriole | Macula densa |
| Simple cuboidal epithelial cells | Most of the DCT is composed of : |
| Simple cuboidal epithelium consisting of principal and intercalated cells | Last part of the DCT AND collecting duct is composed of: |
| 1. macula densa 2. juxtaglomerular cells of the afferent arteriole | What makes up the juxtaglomerular appartus (JGA) |
