Both (A) and (B)

The myogenic mechanism.

Glomerular-tubulo balance.

Tubulo-glomerular feedback.

you lose more salt through the skin.

initially the excess sodium is sequestered in the intracellular compartment.

the excess sodium is rapidly excreted within 2 hours of ingestion.

initially total body water increases which corrects the change in plasma osmolarity.

Dilation of the afferent arteriole or constriction of the efferent arteriole

Dilation of the afferent or efferent arteriole  

Constriction of the afferent arteriole or vasodilation of the efferent arteriole        

Constriction of the afferent or efferent arteriole      

Plasma adrenaline levels.

Plasma atrial natriuretic peptide levels.

Plasma aldosterone concentration.

Plasma angiotensin II levels.

distal tubule

proximal tubule

thin descending limb of the loop of Henle

thick ascending limb of the loop of Henle             

(A), (B) and (C).

plasma atrial natruiretic peptide levels to increase.

plasma angiotensin II levels to increase.

plasma aldosterone levels to increase.

secretion of atrial natriuretic factor would increase.

All of the above would occur.

firing by hypothalamic osmoreceptors would decrease.

urine osmolarity would decrease.

Fall due to fluid pressure in the Bowman’s capsule falling           

Fall due to oncotic pressure of the filtrate falling     

Increase due to oncotic pressure in the Bowman’s capsule increasing  

Increase due to the net filtration pressure across the glomerular capillary increasing
