the thin ascending limb is highly permeable to what?
which tubule receives the ultrafiltrate from the urinary space of Bowman's capsule?
True or False: Distal tubules have a brush border.
small transmembrane protein that functions as a molecular water channel in the cell membrane of proximal convoluted tubules.
the proximal straight tubule, the thin segment, and the distal striaght tubule are collectively known as what?
True or False: Glomeruli are supplied by afferent arterioles and drained by efferent arterioles
ADH regulated water channels in the collecting ducts
the _________ nephrons have their renal corpuscles in proximity to the base of a medullary pyramid
unique capillary network within the renal corpuscle
point where afferent and efferent arterioles enter and exit Bowmans capsule
the _____ nephrons have their renal corpuscles located in the outer part of the cortex
double layered epithelial cup surrounding the glomerulus
this is where the proximal convoluted tubule begins
the thin ascending limb is highly impermeable to what?
2 proteins that are responsible for fluid reabsorption in the proximal convoluted tubule of the kidneys
secretes renin
the ____ convoluted tubule exchanges Na and K ions
this hormone is involved in the regulation of blood pressure. It is released from the kidneys and cleaves angiotensinogen
constitutes the thin portion of the loop of Henle.
central medullary ray and surrounding cortical material
true or false: the kidney is supplied by a venous portal system.
nuclei are located in the apical portion of which type of tubule
an inability of the renal tubules to respond to antidiuretic hormone (ADH) resulting in inefficient water resorption by the collecting tubules.
distal convoluted tubules drain into what?
the Na/K ATPase pumps Na in or out of the cell?
also referred to as the thick ascending tubule of the loop of Henle. Ascends through the medulla to enter the cortex
this glycoprotein regulates RBC formation in response to decreased blood oxygen concentration
collecting tubules or ducts drain urine into what?
space between the visceral and parietal layers of Bowmans capsule
elongated space in between the interdigitating processes that allow the ultrafiltrate from the blood to enter Bowmans space
originates from the urinary pole of Bowmans capsule, follows a very convoluted course and then enters the medullary ray.
an area of closely packed specialized cells lining the wall of the distal tubule at the point of return of the nephron to the vascular pole of its parent glomerulus, (glomerular va
arteries in between the medulla and cortex of the kidney
special capillary network of the medulla
true or false: the distal straight tubule is a continuation of the thin ascending limb and it pumps ions from the tubule lumen to the interstitium
True or False: the proximal convoluted tubule aids in digestion of peptides and disaccharides
the thin descending limb is highly permeable to what?
capillaries of the renal medulla
True or False: The cells of the proximal straight tubule are more specialized that that of the proximal convoluted tubule.
when ultrafiltrate enters the loop of henle it is isoosmotic to plasma. when it leaves it is what?
commonly referred to as the thick descending tubule of the loop of Henle. Descends into the medulla.
the interdigitating processes of proximal convoluted cells are composed of?
the basal striations of the proximal convoluted tubule contain which organelle?
this hormone regulates the water permeability in collecting ducts by acting AQP2
basic functional unit of the kidney
these cells provide structural support and act as macrophages in the GBM of the kidney
visceral epithelial cells that extend processes around the glomerular capillaries
capillaries of the renal cortex
acts a a physical barrier and ion selective filter in the kidney
these transmembrane proteins are responsible for the reabsorption of Na, which is the major driving force for the resorption of water in proximal convoluted tubule.
