3
Regarding glomerular capillary endothelium which of the following statements is
false
?
Mesangial cells are contractile, allowing blood flow
Contain large pores that allow most substances to pass
Glomerular capillaries are defenestrated
Cells are too large to pass through so they are retained
4
Net filtration is glomerular capillary pressure, plasma osmotic pressure and Blood pressure?
False
True
5
Which is
not
one of the barriers that substances must pass through for kidney filtration?
Glomerular capillary endothelium
Proximal tubule
Bowman's capsule epithelium (podocytes)
Basal Lamina
6
In comparison to other capillary beds glomerular capillaries are important because?
2. Filtration occurs through entire length of capillary bed
1. Glomerular capillaries are highly permeable
Both 1 and 2
3. Acts as a sieve to prevent filtration of plasma proteins
7
Filtration happens exclusively in the …..?
Peritubular capillaries
Bowman's capsule
Renal Tubule
Glomerulus
8
Tubular secretion is the transfer of substances from the peritubular capillaries to the ….?
Peritubular capillaries
Tubular fluid
Glomerulus
Tubluar lumen
9
GFR is define as the 1……… of fluid that is filtered at the 2……… per unit time.
1. Type 2. Glomerulus
1. Volume 2. Nephron
1. Type 2. Nephron
1. Volume 2. Glomerulus
10
Presence of protein in the urine can indicate damage to the filtration barrier. This is called?
Haematuria
Proteinuria
None of the answers
Glycosuria
11
What is the path of blood flow in the kidneys? (AA=Afferent arteriole; EA= efferent arteriole)
AA, EA, glomerular capillaries, peritubular capillaries
AA, glomerular capillaries, EA, peritubular capillaries
AA, peritubular capillaries, EA, glomerular capillaries
EA, glomerular capillaries, AA, peritubular capillaries
12
In the basic renal process reabsorption occurs from the tubular lumen back into the …..?
Glomerulus
Bowman's capsule
Peritubular capillaries
Tubular fluid
13
Regarding basal Lamina which of the following statements is false?
Extracellular matrix contain positively charge glycoproteins
The negatively charge proteins help to repel plasma proteins
Extracellular matrix between glomerular and bowman’s capsule
Acts as a sieve to prevent the filtration of plasma proteins
14
Which of the following is not one of the forces that drives filtration?
Glomerular capillary hydrostatic pressure
Bowman’s capsule hydrostatic pressure
Plasma osmotic pressure (oncotic pressure)
Blood osmotic pressure (lymphatic pressure)
15
Basic renal process- reabsorption is the 1.. movement and tubular secretion is the 2.. transfer
1. Exclusive 2. Selective
1. Selective 2. Selective
1. Exclusive 2. Exclusive
1. Selective 2. Exclusive
16
Regarding Podocytes which of the following statements is false?
Podocytes surround the glomerular capillary
They have short extensions that wrap around the lamina
Cells and plasma proteins are retained within the blood
The slits that form are the final barrier to filtration
17
Which of the following is not a factor that would affect GFR?
Low white blood cell count
Urinary tract obstruction
Severe dehydrating diarrhea
Low plasma albumin
