  1. 1Surrounding the kidney from superficial to deep are?
    1. Ainferior renal capsule, superior renal capsule, paranephric fat, fascia, perinephric fat
    2. Binferior renal capsule, superior renal capsule, perinephric fat, fascia paranephric fat
  2. 2The kidney is a retroperitoneal structure. The renal hilum (entrance to the kidney) has three vessels enter. From anterior to posterior they are?
    1. ARenal artery, Renal vein, Renal Pelvis
    2. BRenal Pelvis, Renal vein, Renal Artery
    3. CRenal Vein, Renal Artery, Renal Pelvis
  3. 3The right renal artery is _____and passes _____to the IVC.
    The left renal vein is____ and receives the L) _____________. Each vein drains into the _______
    1. Alonger
    2. Bposterior
    3. Cshorter
    4. Dsuprarenal
    5. EIVC
  4. 4Each nephron is an independent entity until the point at which its collecting ducts merge with other collecting ducts. The nephron consists of a [blank_start]glomerulus[blank_end] and tubule. The glomerulus is a cluster of blood vessels from which the plasma filtrate originates. The tubule is an epithelial structure consisting of many subdivisions including the PCT, thin descending limb, thick ascending limb and the DCT.
    1. Aglomerulus
    2. Bbowmans capsule
    3. Carteriole
  5. 5Within the renal cortex there are two types of populations of nephrons. Superficial nephrons and [blank_start]juxtamedullary[blank_end] nephrons which play a special role in [blank_start]concentration[blank_end] of urine, having [blank_start]long[blank_end] loops of henle.
    1. Ajuxtamedullary
    2. Bintermedullary
    3. Cconcentration
    4. Ddilution
    5. Elong
    6. Fwide
    7. Gshort
  6. 6Label these structures of the kidney?Bild zu Frage 6
    1. AMedulla
    2. BInterlobular arterioles
    3. CRenal artery
    4. DRenal vein
    5. EHilum
    6. FPelvis
    7. GUreter
    8. HMinor calyx
    9. ICapsule
    10. JNephrons
    11. KMajor Calyx
    12. LRenal Papilla
    13. MRenal Column
  7. 7The PCT has cuboidal epithelium with microvilli to increase surface area. The DCT has?
    1. Acuboidal epithelium
    2. Bmicrovilli
    3. Cstratified squamous epithelium
    4. Dno microvilli
  8. 8The control of blood flow in the kidney occurs by:
    1. [blank_start]Myogenic Response[blank_end]- Afferent arterioles have an ability to respond to changes in vessel circumference by contracting or relaxing Mechanism in response to opening of [blank_start]stretch-activated[blank_end] non-selective cation channels, depolarising the cell and leading to an influx of [blank_start]calcium.[blank_end]
    2. [blank_start]Tubuloglomerular Feedback[blank_end]
    The filtrate is detected by the Juxtaglomerular apparatus (macula densa cells) and in response to an increase in GFR, translate this into contraction of the [blank_start]afferent[blank_end] arteriole. The [blank_start]JGA[blank_end] mediates this response.
    1. AMyogenic Response
    2. BNeurogenic Response
    3. CVascular Response
    4. Dstretch-activated
    5. Evoltage gated
    6. Fcalcium.
    7. Gsodium
    8. Hpotassium
    9. ITubuloglomerular Feedback
    10. JJuxtamedullary feedback
    11. Kafferent
    12. Lefferent
    13. MJGA
    14. NNa-K-ATPase pump
  9. 9An important feature of the renal circulation is its ability to maintain RBF and GFR within narrow limits, even though MAP may vary between?
    1. A80 and 170mmHg
    2. B50-200mmHg
    3. C50-170mmHg
    4. D80-220mmHg
  10. 10Factors that increase sensitivity of TGF are: volume contraction, [blank_start]adenosine[blank_end], PGE2, TXA2, Ang 2.
    Factors that decrease the sensitivity of TGF are: volume expansion, [blank_start]ANP[blank_end], NO, cAMP, PGI2,
    1. Aadenosine
    2. BcAMP
    3. CEndothlelin
    4. DANP
    5. EAdenosine
    6. FEndothelin
