Question

ANSWER ALL PLEASE

12. the sympathetic nervous system causes changes in the afferent arteriole diameter, this will lead to;

a. decreased glomerular filtration rate (GFR) and decreased blood volume

b. decreased glomerular filtration rate (GFR) and increased blood volume

c. increased glomerular filtration rate (GFR) and decreased blood volume

d. increased glomerular filtration rate (GFR) and increased blood volume

10. during glomerular filtration___ stay in the blood and ____ enter the urinary filtrate.

a. glucose and nutrients; proteins and blood cells

b. proteins and blood cells; fluid and small moleules

c. urea and nitrogenous waste; fluid and small molecules

d. water and sodium; urea and nitrogenous waste

5. fluid from the nephron is reabsorbed into the

a. afferent arteriole

b. loop of henle

c. particular capillaries

d. proximal convoluted tubule

Answer 1

Answer

12. Option B) Decreased glomerular filtration rate (GFR) and increased blood volume

• Sympatthetic stimulation to afferent arteriole will lead to vasoconstriction of afferent arteriole.
• As diameter is reduced, resistance will increase and capillary hydrostatic pressure decreases.
• GFR decreases. As filtrate production is low, blood volume increases.  

10. Option B) Proteins and blood cells; fluid and small moleules

• The filtration membrane allows small molecules to enter the Bowman's capsule as filtrate.
• Large molecules such as proteins and blood cells remains in blood.

5. Option C) Peritubular capillaries

• These capillaries rung along the nephron tubule.
• Ions and nutrients reabsorbed from nephron tubule enters into peritubular caplllaries.
