Q

Describe the route of the ureters

A

Descend down the spine along the tips of the transverse processes

At sacroiliac joints, ureters cross the pelvic brim and enter the pelvic cavity

Once in pelvic cavity, ureters run down lateral pelvic wall and at level of ischial spines they turn anteromedially and move towards the bladder

Q

What is number 14

A

Renal cortex

17
Q

Describe the renal blood supply

A

Kidneys are supplied by left and right renal arteries

Kidneys are drained by left and right renal veins - left renal vein is longer as it crosses over the aorta

18
Q

What veins drain into the left renal vein

A

Left adrenal vein

Left gonadal vein

19
Q

Describe the route of ultra-filtrate through the nephron

A

Filtered at glomerulus -> enters PCT -> enters loop of Henle -> enters DCT -> enters collecting duct

20
Q

Where are the parts of the nephron found, in relationship to the overall kidney structure

A

Glomerulus, PCT, DCT and proximal collecting tubule are found in the renal cortex

Loop of Henle and distal collecting tubule are found in renal medulla

21
Q

What is the bladder and what is it formed of

A

The bladder is a expandable, muscular bag

It is formed of the detrusor muscle

22
Q

What are the entrances and exits of the bladder - what do they form

A

Two internal ureteric entrances for ureters

One internal urethral meatus for urethra

Form the trigone

23
Q

What is significant about the trigone

A

It is non-distensible

24
Q

What pouches are found behind the bladder

A

Men - recto-vesical pouch

Women - vesico-uterine pouch

25
Q

Where can the bladder be palpated

A

Above the symphysis pubis, but only when it is full as it moves upwards into the abdominal space when full
