|
Three Layers of tissue surrounding each kidney
|
Renal capsule
Adipose Capsule Renal Fascia |
|
|
Nephroptosis
|
Floating Kidney
|
|
|
Renal Papilla
|
Apex of pyramids
|
|
|
Renal Lobe
|
A renal pyramid, overlying renal cortex, and one half of each adjacent renal column
|
|
|
Parenchyma
|
Functional portion of kidney
Renal Cortex & renal pyramids |
|
|
Two parts of Nephron & their parts
|
Renal Corpuscle - Glomerulus & glomerular capsue
Renal tubule - Proximal convoluted tubule, loop of henle, distal convoluted tubule |
|
|
Two types of nephrons, which ones are more abundant and where are thick and thin ascending limbs found?
|
85% are cortical nephrons
15% are Juxtamedullary nephrons & have long renal tubules with thick and thin ascending limbs |
|
|
Podocytes
|
Footlike projections that form inner wall of the capsule
|
|
|
Macula Densa
|
Region near the afferent arteriole that seem crowded together
|
|
|
Juxtaglomerular cells
|
Found alongside the macula densa and the afferent arteriole & together with macula densa forms juxtaglomerular apparatus which helps regulate BP
|
|
|
Two different cells in the last part of the DCT & their functions
|
Principal cells which contain receptors for ADH and aldosterone
Intercalated cells which helps to maintain blood pH |
|
|
Tubular Reabsorbtion & tubular secretion
|
Reabsorbtion moves fluid and solutes out of tubule
Secretion moves fluid and solutes into tubule |
|
|
Filtration Fraction
|
Fraction of blood plasma in afferent arterioles of kidneys that become glomerular filtrate
|
|
|
Mesangial Cells
|
Contrctile cells that help glomerular filtration
|
|
|
Three barriers of Filtration membrane
|
Glomerular Endothelial cells
Basal Lamina Podicytes that form pedicles |
|
|
3 Forces governing net Filtration Pressure
|
Glomerular Blood hydrostatic Pressure
Capsular Blood hydrostatic Pressure Blood colloid osmotic pressure |
|
|
2 Hormones regulating GFR
|
Angiotensin II which is a potent vaso constrictor and decreases GFR
ANP atrial natriuretic peptide which increases GFR by causing relaxation of glomerular mesangial cells |
|
|
Two sides of tubular cells
|
Apical membrane facing the filtrate & basolateral membrane facing the blood vessel
|
|
|
Obligatory and Faculative water reabsorption
|
Obligatory is 90% and occurs in PCT and descending loop of henle
Faculative is 10% and occurs in Collecting duct |
|
|
3 Layers of Ureters
|
Mucosa - Transitional epithelium & lamina propria
Muscularis Adventitia anchors it in place |
|
|
Detrusor muscle
|
Muscularis of Urinary Bladder
|
|
|
Serosa
|
Visceral peitoneum layer on top of urinary bladder
|
|
|
Micturition
|
Urination
|
|
|
3 regions of male urethra
|
Prostatic Urethra
Muscularis urethra Spongy Urethra |
