ureters
urinary bladder
urethra
2. kidney (shape, weight, location) - correct answer ✅bean shaped / size of soup can,

is slightly lower than the left b/c of the liver above it
3. adrenal glands - correct answer ✅a pair of endocrine glands that sit just above the
kidneys and secrete hormones (epinephrine and norepinephrine) that help arouse the
body in times of stress.
4. renal hilus (hilum) - correct answer ✅a notch located near center of medial concave
side of the kidney / the passageway to renal sinus for vessels and ureter
5. 3 layers of kidney tissue (outermost to innermost) - correct answer ✅renal fascia
(outer, fibrous connective tissue, keeps kidney in place), adipose capsule (middle, fatty
layer protects kidney from trauma), renal capsule (inner layer of protective tissue
projects kidney from injury + infection)
6. 3 regions of kidney (outermost to innermost) - correct answer ✅cortex, medulla, renal
pelvis
7. renal pelvis (of kidney) - correct answer ✅central collecting region in the kidney,
extensions of the pelvis (calyces) collect urine and drain continuously into pelvis and
then into ureter
8. kidney blood supply chain - correct answer ✅Abdominal aorta -> renal artery ->
segmental artery -> lobar artery -> interlobar artery -> arcuate artery -> interlobular
artery -> afferent arteriole -> glomerular capillaries / filtration / efferent arteriole ->
peritubular capillaries (deoxygenated) or vasa recta -> interlobular vein -> arcuate vein -
>interlobar vein -> renal vein which exits kidney

bladder / inner layer made of transitional epithelium, continuous with kidney's lining
16. 3 layers of bladder wall (outermost to innermost) - correct answer ✅outer fibrous
connective tissue layer / middle detrusor muscle layer / inner mucosal layer made of
transitional epithelium specialized to enable cellular expansion to absorb fluid
17. Describe the bladder when it is full and when it is empty. - correct answer ✅When
filled with urine, the bladder swells and becomes pear-shaped, raising in the abdominal
