Structure, and Urinary System | Verified Exam Q&A
Description:
This study document provides detailed verified exam questions and answers on the
kidney’s anatomy and embryology. It covers nephron structure, urine formation,
renal physiology, and developmental stages including pronephros, mesonephros,
and metanephros. It also explains anomalies, renal ascent, and the urogenital
system. A key resource for medical and anatomy students.
corresponding vertebrae with kidney locatoin - answer✔✔T12 to L3 *renal hilum,
L2* *(renal vein, artery, pelvis) *anterior -> -> -> posterior renal papilla (urine is
released from collecting ducts) - answer✔✔lies in ONE minor calyx 2-3 minor
calices = major calyx => renal pelvis renal medula, cortex and renal columns on CT -
answer✔✔*cortex brightest due to high blood flow to area + contrast *renal
cortex receives 90% of RBF Components of renal corpuscle - answer✔✔Bowman's
capsule: cup-like sac (B) at the proximal end of a nephron invaginated by ->
Glomerulus: tuft of capillaries (A) nephron anatomy summary - answer✔✔
Structures of cortex and medulla - answer✔✔Cortex: glomeruli, blood vessels, and
, all parts of the renal tubules except for the loops of Henle Medulla: loops of Henle
and vasa rectae path of urine from collecting duct - answer✔✔collecting ducts ->
calyces (minor -> major) -> renal pelvis -> ureter -> bladder in addition to urine

production, key functions of the kidney - answer✔✔regulating blood pressure, the
composition of body fluids, acid-base balance Separation of kidney units by function -
answer✔✔• Nephrons = the excretory units of the kidneys • Collecting system =
ducts and ureters • Urinary bladder and urethra kidney and gonades develop from
which embryonic layer? - answer✔✔intermediate mesoderm "urogenital ridge"
*kidneys from 'nephrogenic cord'* mesonephric duct and tubules are shared with
the developing ______ - answer✔✔gonads and urinary system mesonephric duct
-> ureteric bud -> ureters to collecting duct *mesonephric duct becomes sperm
carrying tubes of male reproductive system* *vestigal in females Pronephros -
answer✔✔i. Tubules (nephrons) form at 4 weeks in cervical region, 1 per body
segment ii. Degenerates iii. Pronephric duct extends to cloaca (common sac at the
ends of the genitourinary and intestinal tracts) iv. Pronephric duct becomes
mesonephric duct Mesonephros - answer✔✔i. Appears late in 4th week ii. Forms
interim kidney - functions from *5th - 10th* weeks iii. S-shaped mesonephric
tubules, 3-4 per body segment 1. One end becomes Bowman's capsule around a tuft
of capillaries (glomerulus) 2. Other end taps into the mesonephric duct 3.
Mesonephric (Wolffian) duct becomes sperm-carrying tubes of the male
reproductive system; mesonephric duct system is vestigial in females 4. Cranial
