urinary bladder
The ______________exits the urinary bladder and takes the urine outside of the body
urethra

renalcortex
The _____________ ____________ makes up the inner portion of the kidney and is arranged in ____________ ____________.
renalmedulla
renal pyramids
_____________ ___________ separate the renal pyramids.
Renal columns
The ___________ ____________ is a connective tissue sheath surrounding the kidney.
renal capsule

into the ________ __________
into the __________ __________
into the__________ __________
intothe__________ __________
into the ___________
into the ___________ __________
into the ____________ that takes urine out of the body
renal papilla
minor calyx
major calyx
renal pelvis
ureters
urinary bladder
urethra
_____________ are muscular tubes that transport urine from kidneys to bladder via ___________.
Ureters
peristalsis
Urinary bladder includes two types of specialized tissue:
Smooth muscle called the _______________ that lines bladder and will squeeze out urine when necessary
________________ _______________ can stretch with increased volume
detrusor
Transitional epithelium
_______________ marks the points of an anatomical triangle: two ureters, one urethra
Trigone
Urethral ______________ regulate the removal of urine
sphincters
________________ urethral sphincter is between the urinary bladder and the urethra; is involuntary
Internal
_____________ urethral sphincter is between urethra and outside the body; is voluntary
External
Male urethra is longer than the female’s, with three distinct regions:
Prostatic urethra
Membranous urethra intermediate
External urethral sphincter here
Penile urethra
The kidneys will remove…?
Excess Solutes
Nitrogenous Wastes
Water
___________________ is the process of reclaiming solutes and water from the urinary system back into the blood
Reabsorption
The kidneys accomplish excretion and reabsorption with _______________, the functional unit of the kidney
nephrons
Three processes occur within the nephron to form urine:
Filtration
Reabsorption
Secretion
Glucose reabsorbed into ______________ capillaries
peritubular
Proximal Convoluted Tubule (PCT)
Absorbs water and NaCl
Aids in regulating final urine volume
Loop of Henle
Absorbs water, salts and other nutrients
Secretion of ____________ that escaped filtration
Distal Convoluted Tubule (DCT)
wastes
No secretion or absorption here
Collecting Duct
The first portion of the nephron is ______________ _____________, which surrounds the ________________.
Bowman’s capsule
glomerulus
Filtration occurs at ______________ ________________.
Bowman’s capsule
Any portion of blood that is too large cannot pass into the nephron but will move through the ____________ _______________ to stay in the blood stream
efferent arteriole
Reabsorption occurs mainly in the ____________ ____________ ____________. (PCT)
primary convoluted tubule
Water and NaCl balance occurs in the ___________ ____ ___________.
Loop of Henle
As a result, urine is _________________ at the Loop of Henle
concentrated
Secretion: movement of substances from the blood stream into the _____________ of the nephron
lumen
__________________ ____________, detect blood pressure
Cause more water to be moved from the blood into the nephron if blood pressure is too high
Juxtaglomerular cells
The _____________ ____________ detect ion concentration
macula densa
The juxtaglomerular apparatus is comprised of:
Juxtaglomerular cells
macula densa
______________: Glucose in the urine
Glycosuria
_________________: Bile pigments and bilirubin present in the urine
Bilirubinuria
______________: Ketone bodies in the urine
Ketonuria
________________: Blood present in the urine
Hematuria
__________________: Albumin present in the urine
Albuminuria
