-
What does the urinary system consist of?
- Two kidneys
- two ureters
- bladder
- urethra
-
What is the function if the kidneys
- Form urine to excrete waste productsÂ
- regulate the volume, electrolytes and pH of blood and tissue fluid
-
What is the function of adipose tissue and renal fascia in the kidney?
Cushion and help hold in place
-
What is the hilus?
An indentation on the medial sides of the kidneys, where renal arteries enter and where renal veins and ureter emerge
-
Renal cortex
Outer tissue layer, made of renal corpuscles and convoluted tubules
-
Renal medulla (pyramids)
Inner tissue layer, made of loops of henle and collecting tubules
-
Renal pelvis
A cavity formed by the expanded end of the ureter within the kidney at the hilus
-
Calcyes
- Extensions around the papillae of the pyramids
- collect urine
-
renal corpuscle
- In nephron
- consists of a glomerulus surrounded by a bowmans capsule
-
Glomerulus
Capillary network between an afferent arteriole and an efferent arteriole
-
Bowmans capsule
- The expanded end of a renal tubule that encloses the glomerulus
- inner layer made of podocytes
- has pores
- very permeable
- contains renal filtrate
-
Renal tubule
Consists of the proximal convoluted tubule, loop of henle, distal convolute tubule, and collecting tubule
-
Collecting tubule
Unites to form papillary ducts that empty urine into the calyces of the renal pelvis
-
Pertibular capillaries
arise from the efferent arteriole and surround all parts of the renal tubule
-
pathway of blood vessels in the kidney
- abd aorta
- renal artery
- interlobar arteries
- arcuate arteries
- interlobular arteries
- afferent arterioles
- glomeruli
- efferent arterioles
- peritubular capillaries
- interlobular veins
- arcuate veins
- Interlobar veins
- renal vein
- inferior vena cava
