Anatomy Flashcards
A bean shape organ that is responsible for the urine formation.
Kidney
The location of the kidney

Thickness of the kidney
2-3 cm
Why is the right kidney slightly lower than the left kidney?
Because of the presence of the liver in the right
How much cardiac output does the kidney receive?
20-25%
A interstitial distinct region of the kidney that is light in color and granular in appearance. It also contains the glomerulus
Cortex
A tough of capillaries surrounded by bowman’s capsule responsible for filtration
Glomerulus
A interstitial distinct region of the kidney that contains the loop of henle, vasa recta and the renal pyramid
Medulla
How wide is the medula
5cm
Responsible for water reabsorption
Loop of henle
Responsible for normal renal blood flow for the normal tissue perfusion
Vasa recta
Site for urine flow out which exits the renal pelvis
Renal pyramid
A interstitial distinct region of the kidney that is responsible for water reabsorption
Renal pelvis
It is responsible for urine formation and each kidney contained 1 million of this
Nephron
Normal glomerulus filtration rate
125 ml/min
Total urine per hour
40-60 ml/hr
Total urine per day
1500 ml/day
A type of nephrons that is responsible for urine formation
Cortical nephron
A type of nephron that mainly produce renin
Juxtamedullary nephrons
Enumerated the function of kidney
Urine formation
Excretion of waste product
Regulates electrolytes

A muscular hollow sac that serves as an opening if ureters and urethra
Urinary bladder
Over all location of the urinary bladder
Posterior to the symphysis pubis
Behind the pubic bone
Location of urinary bladder for male
Lies immediately in-front of the rectum
Location of the urinary bladder for female
Lies in-front of the vagina
How many ml of urine does the urinary bladder hold
500-800 ml
A thin walled muscular tube that serves as a passage way of urine out of the body
Urethra
Size of the female urethra
1-2.5 inches (2-3 cm)
Size of the male urethra
5-6 inches (20cm)
Muscle layer that allows the bladder to expand or contract and dilates
Detrusor
Smooth triangular portion of the base of the bladder
Trigone wall
Passage way of urine form the renal pelvis to the bladder
Ureters
How long is the ureter
12-20 inches
