What area do the kidneys lay in? - Correct answer ✔The retroperitoneal cavity which is
|| || || || || || || || || || || || || || ||
behind the abdominal cavity.
|| || ||
Structure that covers the kidneys? - Correct answer ✔renal capsule
|| || || || || || || || ||
Kidneys are further wrapped in adipose tissue then: - Correct answer ✔a double layer of
|| || || || || || || || || || || || || ||
connective tissue called renal fasca.
|| || || || ||
What is the area where the renal vessels and ureter exit and enter? - Correct answer
|| || || || || || || || || || || || || || || ||
✔hilum.
The center of the concave portion of the kidney.
|| || || || || || || ||
If lose significant amount of body weight can end up having difficulty with kidneys bc: -
|| || || || || || || || || || || || || || || ||
Correct answer ✔bc fat pad that surrounds kidneys can be used up and cause kidneys
|| || || || || || || || || || || || || || ||
to drop inferiorly (ptosis). Leads to kinking of ureter or renal vessels.
|| || || || || || || || || || ||
Kidney extends beneath ____ rib to level of ____ __________ vertebrae. - Correct
|| || || || || || || || || || || || ||
answer ✔12th rib; || ||
3rd lumbar vertebrae.
|| ||
Which kidney is lower and why? - Correct answer ✔the right kidney is lower bc liver
|| || || || || || || || || || || || || || ||
,2
Outer portion of kidney? - Correct answer ✔cortex
|| || || || || || ||
what is contained in the cortex? - Correct answer ✔glomeruli and beginning of nephrons
|| || || || || || || || || || || || ||
including glomerulus, Bowman's capsule or renal corpuscle.
|| || || || || || ||
function of cortex? - Correct answer ✔starts filtration process
|| || || || || || || ||
inner layer of kidney - Correct answer ✔medulla.
|| || || || || || ||
Structures contained in the medulla: - Correct answer ✔renal pyramids, loop of henle,
|| || || || || || || || || || || || ||
vaso recta.||
these set up the concentration gradient = concentrate urine.
|| || || || || || || ||
Where do the collecting ducts pass through? - Correct answer ✔the renal pyramids and
|| || || || || || || || || || || || || ||
exit facing toward the hilus.
|| || || ||
Tip of renal pyramid is called: - Correct answer ✔papilla.
|| || || || || || || || ||
where fluid and urine will leak/drip out from renal pyramid into collective funnel shape
|| || || || || || || || || || || || || ||
structures = calyces. || ||
Major calyces combine to form: - Correct answer ✔the renal pelvis. It exits out the
|| || || || || || || || || || || || || || ||
hilum to form the ureter.
|| || || ||
What is the functional unit of the kidney? - Correct answer ✔nephron
|| || || || || || || || || || ||
, 2
How to differentiate b/t nephrons: - Correct answer ✔how deep the loop of henle
|| || || || || || || || || || || || || ||
extends into the medulla.
|| || ||
amount nephrons per kidney: - Correct answer ✔1.2 million
|| || || || || || || ||
Types of nephrons: - Correct answer ✔1. cortical - least extending into medulla.
|| || || || || || || || || || || ||
2. midcortical - middle length extension.
|| || || || ||
3. juxtamedullary - extend furthest.
|| || || ||
Which nephron will be used to preserve water and concentrate urine? - Correct answer
|| || || || || || || || || || || || || ||
✔juxtamedullary - more will flow here. || || || || ||
*desert animals have entirely these.
|| || || ||
Functions of nephron: - Correct answer ✔1. concentration of urine.
|| || || || || || || || ||
2. retention of water.
|| || ||
3. reabsorption of key substances.
|| || || ||
4. secretion of other substances.
|| || || ||
*where much of the work of the kidneys is done.
|| || || || || || || || ||
structures in the renal corpuscle: - Correct answer ✔1. glomerulus.
|| || || || || || || || ||
2. bowman's capsule.
|| ||
3. mesangial cells.
