Which of the following is/are true concerning kidney structure?
a.
The 'hilum' is the concave part of the kidney through which everything entering or leaving the kidney goes
b.
The kidney is surrounded by a thin connective tissue capsule
c.
Urine collects in the renal sinus
d.
The renal medulla contains the renal corpuscles
e.
Each kidney contains about a million nephrons
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…
