Anatomy 14 - The Urogenital System Flashcards
What is the urinary system composed of
The kidneys, ureter, bladder and urethra
What are the main functions of the urinary system
To filter the blood, conserve/release water and ions, create and store urine, and release urine as a waste product
Function of the kidneys
To filter the blood to create urine
How do the kidneys filter the blood

What surrounds the kidneys
A capsule
What sits at the apex of the kidneys
The supra-renal glands
Where does the renal vessels and ureter enter/exit the kidney from
The hilus
Where does the renal artery come from
The aorta
Where doe the renal veins drain into
The inferior vena cava
Where does filtration of the blood occur
In the medulla
What makes up the kidney cells
The cortex and the medulla
What is the path of urine thought the kidney
Medulla -> small collecting ducts -> minor calyx -> major calyx -> renal pelvis -> ureter
What are the kidneys surrounded by
Perirenal fat pads
What supplies the suprarenal glands
The suprarenal vessels
What are the suprarenal glands involved in
Endocrine functions
What are the ureters
Smooth muscle tubes passing from the renal pelvis to the urinary bladder
Where is the starting point of the ureter
L1
Where does the urinary bladder sit
Behind the pubic bone
What pushes the bladder forward
The peritoneum
What is the function of the bladder
To be a urine store
What lines the bladder
Containment epithelia
What drains the bladder
