Question

1.) Renal & Nephon Physiology

A- A person is overhydrated. (Drinking tap water – hypoosmotic solution) What is their ADH level compared to normal?

B- What will be the result in urine production? (Increase or decrease)

C- What will the osmolarity of the urine be compared to normal? (high or low)

D- A different person has become dehydrated in the desert. What is their ADH level compared to normal?

E- What will be the result in urine production? (Increase or decrease)

F- What will the osmolarity of the urine be compared to normal? (high or low)

G- Where in the nephron is the target of ADH action?

H- What can the kidneys do to compensate for acidosis?

I- What can the kidneys do to compensate for alkalosis?

A. ADH level of an overhydrated person is low compared to normal

B. Which results in increase in urine production

C. Osmolarity of urine slightly decreases.

D. When person become dehydrated ADH level increases to conserve water in body

E. Which results in decrease in urine production

F. Osmolarity of urine compared to normal increases or no changes seen

G. ADH acts mainly on collecting tubule and distal convoluted tube where receptors of ADH presents

H. During metabolic acidosis, bicarbonate buffer equation shifted to left which means decrease in excretion

I. During metabolic alkalosis, increase in secretion of bicarbonate ion seen.
