A person must remove mOsmol of solute in a day.
- How many litres of urine are passed if the urine is at mOsmol/L?
- How many litres if it is at mOsmol/L?
- How many litres if it is at mOsmol/L?
Need a reminder? The key ideaShow
ADH is made in the hypothalamus and released by the neurohypophysis. It helps the reabsorption of water and prevents diuresis. Renin from the JG cells changes angiotensinogen to angiotensin I and II. Angiotensin II narrows the vessels and makes the adrenal cortex release aldosterone. ANF from the atria widens the vessels and lowers the blood pressure. In a model, the urine volume is .
The worked solution
Have you tried it?
Work it out on paper first. It is fine to get stuck or make a mistake: that is how we learn. When you are ready, go through the solution one step at a time, and check each step against your own.
Given. Solute: mOsmol a day.
Plan. .
Step 1. At . L.
Step 2. At . L.
Step 3. At . L.
Answer: L; L; L.
Check. The more concentrated the urine, the smaller the volume.
Source. The solute load of mOsmol a day is a physiology book value (Guyton and Hall, 14th edition). It is not in NCERT.
