Podocytes
Function of ureter
Transport of urine from kidney to urinary bladder

Secrete mucous to capture pathogen
Function of macula densa
Relay information such as osmolarity in tubule and regulates glomerular filtration
Epi of penile urethra
Pseudostratified columnar
Urine is nothing more than
Modified blood plasma
Basement membrane in renal corpuscle stops
Ions from passing though
Function of mitochondria in proximal convoluted tubule
Produce energy to move ions
The podocytes have several primary processes that divide into
Secondary processes called pedicels
What is the second layer of filtration slits

What are littres glands
Mucous secreting gland in urethra
Epi of proximal convoluted tubule
Simple cuboidal epi with microvilli (absorption)
The lamina densa in the renal corpuscle is surrounded by
Lamina rara
Thick segment of loop henle lined with
Simple cuboidal no microvilli
Podocytes wrap around
Capillary
Proximal convoluted tubule is acidophilic because of
High numbers of mitochondria
Function of mesangial cells
Macrophage of kidney that are mobile
What brings blood into the glomerulus

The pedicele slits block
Protein such as albumin
Epi of membranous urethra
Stratified columnar to pseudostratified columnar
What are the two layers of Bowmans capsule
Visceral and parietal
The glomerulus is made up of
Capillary bed
Function of loop of henle
Absorb water, responsible for concentration of urine
Describe lumen of proximal convoluted tubule
Collapsed
What is the vascular pole of the renal corpuscle
Where afferent, efferent and glomerulus is located
