61: Urinary System Flashcards
Bean shaped Retroperitoneal organs, situated lateral to the vertebrae T12-L3
Kidneys
Which kidney is located higher in the abdominal cavity?
The Left Kidney
The hilum of the kidney faces medially and contains:
- Renal vein
- Renal artery
- Renal pelvis
The left kidney is located at the level of rib… and rib….
The right kidney is located at the level of rib….
Lt: Rib 11 and 12
Rt: Rib 12
- Connective tissue closely adhered to the kidney
- Also enters the renal hilum and lines the renal sinus
- Continuous with the connective tissue forming the walls of the calyces and renal pelvis
Renal Capsule
The renal capsule is surrounding by a layer of…..
Extra-peritoneal fat (Perirenal/Perinephric fat)
Enclosing the perirenal fat is a membranous condensation of the ………… that also encloses the adrenal gland.
Extraperitoneal fascia
– Renal fascia
Space superior to the right kidney, posterior to the liver that where Fluid in the abdomen would accumulate when the body is supine
Hepatorenal recess (Pouch of Morrison)
The Hepatorenal recess is also investigated during a ……….. exam
FAST exam
The internal structure of the kidney is divided into the ……… and the ………
Outer Cortex and Inner Medulla
- A continuous band of tissue surrounding the medulla
- Has extensions into the medulla known as the renal columns
- Contains all the renal corpuscles
Cortex
- Divided into triangular pyramids by the renal columns
- Contains the continuation of collecting ducts and tubules
- Each renal pyramid has a papilla which drains into a minor calyx
Medulla
Several minor calyces join to form a major calyx, which join to form the……….
Renal Pelvis
The renal pelvis exits the hilum and narrows to form the……..
Ureter (ureteropelvic junction UPJ )
The ……… is the basic functional unit of the kidney
Nephron
The renal corpuscle of the nephron contains the ………. and……..
- Glomerulus
* Bowman’s capsule
The tubules of the nephron are:
- Proximal convoluted
- Loop of Henle
- Distal convoluted
Several connecting (collecting) tubules drains into a ………
Collecting duct
Several collecting ducts drains into the ……… via ………..
Minor Calyx
The renal papilla
…………. and ……… together form a Uriniferous Tubule
Nephron and Collecting ducts
Lymphatic Drainage: From Kidney
Into Left and Right Lumbar (aortic and caval) lymph nodes
Lymphatic Drainage: Upper Ureter
Into Kidney Lymphatics or lumbar lymph nodes
Lymphatic Drainage: Middle Ureter
Into Common iliac lymph nodes
Lymphatic Drainage: Lower Ureter
Into Common, external, and internal iliac lymph nodes
Lymphatic Drainage: Pelvic Ureter and Bladder
Into Internal iliac lymph nodes
…………..is formed from rami from the:
• The celiac ganglion and plexus
• The aorticorenal ganglion
• The lower (least) thoracic splanchnic nerves
• The 1st lumbar splanchnic nerve

• Sympathetics are supplied from T11-L2
The renal plexus
The renal plexus usually continues into the kidney around the renal arteries .Most renal nerves are …….
Vasomotor
The renal plexus gives rise to the …………. and ……….. plexuses
Ureteric and Gonadal plexuses
Sensory nerves pass back to the CNS with the ……….
Thoracic splanchnic nerves
