Urogenital System Flashcards
What makes up the urinary system?
Kidneys
Ureters
Bladder
Urethra
Where is the Urinary System located?
Lies in the abdomina and pelvic cavities
True or False: The Urinary System is Anatomically linked with the Genital system?
True
Urogenital System
True/False: The Urinary System and Genital System share the urethra?
True
They share the urethra wich runs through the penis of the male and joins the vagina of the female.
What are the functions of the Kidneys.
Form urine from the blood
Endocrine gland
How much blood perfuses through the kidneys daily and how much urine is produced?
In large dogs - 1000 to 2000 L of blood perfuse the kidneys daily to produce 1 to 2 L of urine
What does Renin do?
Regulates blood pressure
What does Erythropoietin do?
Increases rate of production of RBCs in bone marrow.
Where are the kidneys located?
Found pressed against the abdominal roof in the lumbar region
Right and left of the median plane
Are the Kidneys covered by peritoneum?
No, they are Retroperitoneal - ‘behind peritoneum’
Only the ventral surface of the kidney is covered by parietal peritoneum
True or False: The right kidney is less variable in position than the left kidney?
True
The right kidney is less variable in positon.
What is the location of the Right Kidney?
More cranial than the left by about a half a kidney length
Extends from T13/L1 to L3
What is the location of the Left Kidney?
Extends from L2 to L4
Know the different shapes of Kidneys!
Describe the dorsal surface of the Kidney.
Contacts lumbar hypaxial muscles
free of peritoneum
Describe the ventral surface of the Kidney.
Faces abdominal cavity
Covered by parietal peritoneum
Describe the lateral border of the Kidney.
Convex
Related to abdominal wall/spleen
Descirbe the medial border of the Kidney.
Concave
Related to caudal vena cava/abdominal aorta
Describe the cranial pole of the Kidney.
Right Kidney - caudate process of liver, Right Adreanal
Left Kidney - left lobe of pancreas, Left Adreanal
Describe the caudal pole of the Kidney.
Right Kidney - Ascending colon
Left Kidney - Descending colon, mesovarium (female)
What is the Renal Hilus?
Indented medial border of the kidney is called hilus
Renal b.v., lymphatics, nerves, and the ureter enter
What is the Renal Sinus?
The hilus leads into a recess called the renal sinus.
Contains the renal pelvis, fat, and proximal branches of the renal vessels and nerves.
What is the Renal Pelvis?
Funnel shaped dilatation of ureter
Located inside the renal sinus
Receives urine from the papillary ducts and passes into the ureter
What is the Pelvic Recess?
Curved diverticula of the renal pelvis
Project into parenchyma between renal pyramids
5-6 recesses from each border of pelvis
