- The afferent arteriole delivers blood to the (a) renal artery (b) efferent arteriole (c) renal vein (d) capillaries of the glomerulus (e) peritubular capillariesDuring urine formation, movement of ions against concentration gradient from glomerular iltrate back into the plasma is called: a. Difusion b. Active transport c. Osmosis d. FiltrationThe lumen of glomerular capillaries is lined by: Select one: juxtaglomerular cells. a. b. fenestrated endothelium C. mesangial cells. O d. continuous endothelium. e. podocytes foot processes.
- Which of the following will decrease filtration at the glomerulus? ( check all that apply) A. Low colloid osmotic pressure B. Low capsular pressure C. A relatively large diameter of theefferent arterioles compared to theafferent arteriole. D. Increased number of podocytes at theglomerulusThe glomerulus is what type of blood vessel a. Continuous arteriole b. Fenestrated arteriole c. Sinusoidal capillary d. Fenestrated capillaryWhich of the following is NOT a factor affecting glomerular filtration? a. blood volume b.fenestrae c. renin d hydrostatic pressure e . erythropoietin
- Glomerular filtration can be increased by which of the following? A. Increasing blood flow via afferent arteriole B. Decreasing blood flow via afferent arteriole C. Decreasing arterial blood pressure D. Increasing blood flow via efferent arteriole The answer is (A) Increasing blood flow via afferent arteriole. Please explain why it is not the other options (B,C,D)Which one of the following statements is false?a. Blood pressure in the glomerular capillaries is greater than the osmotic pressure exerted by proteins in the plasma within the glomerular capillaries.b. If the osmotic pressure exerted by solutes in the peritubular capillaries is greater than the blood pressure in those capillaries, then water will be reabsorbed.c. Endothelial cells in glomerular capillaries are highly permeable, facilitating filtration of fluid into Bowman’s capsule.d. Constriction of the afferent arteriole is likely to reduce the volume of filtrate appearing in Bowman’s capsule.e. The efferent arteriole carries blood from the glomerular capillaries directly to the renal vein.0.5 pointsQuestion 2Your doctor calls with the results of your urinalysis and tells you that they found proteinuria, the presence of abnormal amounts of protein in your urine sample. What could have caused this?a. Infection and inflammation in the kidney.b. Abnormally high concentration of plasma…Glomerular colloid osmotic pressure (GCOP) is created by:- a. systemic blood pressure. b. filtrate in the capsular space. c. proteins such as albumin in the blood. d. fluids in the blood plasma.
- Which of these conditions reduces filtration pressure in theglomerulus?a. elevated blood pressureb. constriction of the afferent arteriolesc. decreased plasma protein in the glomerulusd. dilation of the afferent arteriolese. decreased capsular hydrostatic pressureIn which of the following is the blood FILTERED? a. peritubular capillaries b. afferent arterioles d. efferent arterioles c. glomerular capillariesIf the tubular maximum is exceeded, then a. the carrier mechanism will work harder. b. the excess will be reabsorbed in the bladder. c. the excess will appear in the urine. d. its blood concentration will increase.
