Bio 112L Urinary System
Kidney
Produces Urine
Ureter
Transports Urine towards the Urinary Bladder
Urinary Bladder
Temporarily stores Urine prior to Urination
Urethra
Conducts Urine to Exterior (In Males) It also transports Semen
Renal Cortex
Outer light red layer of the Kidney located deep to Fibrous Capsule
Renal Medulla
Consists of Triangular Renal Pyramids
Renal Column
areas of cortex extending between the Renal Pyramids
Renal Lobe
is a Renal Pyramid and accompanying cortex and the adjacent renal columns
Ren Papilla
At the apex of each Renal Pyramid
Minor Calyx
empty into Major Calyx
Renal Pelvis
Calyces merge to form the___?
Nephron
Each Kidney contains 1 million microscopic Tubules called?
Cortical Nephron
Approximately 85% of nephrons are?
Juxtamedullary Nephron
About 15% of Nephrons are?
Renal Corpuscle
Where blood is filtered. And consists of a glomeruralar capsule called Bowmans Capsule
Bowmans Capsule
Houses the Glomerulus
Capsular Space
As filtration occurs, materials are forced out of the blood that is in the glomerulus and into the?
Renal Tubule
Consists of twisted and straight ducts of primary cubodi epithelium.
PCT Promixal Convulates Tublue
First segment of the renal tubule, coming right after the Glomerular capsule is a twisted segment called?
Nephron Loop
Is a straight portion that begins where the PCT turns toward the medulla
Descending Limb
Is mostly a thin tubule that turns back toward the cortex as the ascending limb
Ascending Limb
Leads to a second twisted segment the DCT
Connecting Tubule
A nephron ends where the DCT tubule empties
Capsular Space
Between Capsular Epithelium and Visceral Epithelium
Podocytes
The Visceral Epithelium consists of specialized cells called?
Pedicles
Podocytes wrap extensions called?
Filtration Slit
Small gaps between the Pedicels are pores called?
Ureter
Each kidney has a singlw?
Rugae
Folds in the mucosa of the Urinary Bladder allow the bladder wall to expand and shrink as it fills with Urine ans then empties
Prostatic Urethra
Portion of male Urethra that passes theough the prostrate gland, located inferior to the bladder
IUS AND EUS
Control the voiding of Urine from. bladder
Meniscus
Urine will adhere to the walls of the glass cylinder and form a trough called a?
Ketones
May be a result of stravation, diabetes mellitus or a diet low in carbs
Glucosuria
Indicated diabetes Mellitus
Albumin
A Large Protein molecule that normally cannot pass filtration slits of the glomerulus.
Al-Buminuria
Suggets Increase in the peremability of the glomerurlar membrane
Hematuria
Prescene of Erthrocytes in the urine indication of bleeding caused by inflammation or infection
Pyuria
Lekoycytes in the Urine indicate a UTI
Hemoglobinuria
Urine develops a dark brown to reddish colour
Bilirubinuria
Breakdown of hemoglobin from old red blood cells being removed
Nitrites
Indicate possible UTI
