Osmoconformer and Osmoregulators

The second half of the distal tubule and the cortical collecting tubule of kidneys are equipped with the Principal and Intercalated cells. Of these, the Principal cells reabsorb ${\mathrm{Na}}^{+}$ and excrete ${\mathrm{K}}^{+}$ and are equipped with receptors for the hormone aldosterone. In primary hyperaldosteronism disease, there is an excess production of aldosterone which causes high blood pressure and ${\mathrm{K}}^{+}$ imbalance. Spironolactone, a diuretic drug is generally used to treat these conditions. Choose the correct option for the mode of action of Spironolactone.

The organisms that actively regulate their osmotic pressure, independent of the surrounding environment are called osmoconformers.

Write any two differences between osmoregulators and the osmoconformers.

Few statements about water reabsorption in kidney are given below:

i. Decreased production of anti-diuretic hormone.

ii. Increased osmolality of plasma.

iii. Decreased permeability of kidney tubule epithelium to water.

iv. Increased reabsorption of water.

The consequence(s) of dehydration in an otherwise healthy human would be

What are Osmoregulators?

The organisms that cannot maintain an internal environment that is isotonic to their external environment are called osmoconformers.

 Jellyfish is an example of an osmoconformer.

Give any two examples of osmoconformers.
