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
