<span>The primary organs of the respiratory system are lungs, which function to take in oxygen and expel carbon dioxide as we breathe. The human respiratory system is a series of organs responsible for taking in oxygen and expelling carbon dioxide.</span>
<em>In the inner medulla, urea recirculates, creating a greater osmotic gradient. It follows the concentration gradient formed by ADH-sensitive water reabsorption into the interstitial space from the collecting duct. The remaining water is drawn from the descending structures by increased interstitial osmolarity. </em>
<em></em>
<em>To maintain the vertical osmotic gradient, the blood supply to the renal medulla serves as a countercurrent exchanger. - The medullary vertical osmotic gradient is maintained by the vasa recta.</em>
<em></em>
<em>It enhances both water and urea permeability in the inner medullary collecting ducts, allowing urea to diffuse passively down its concentration gradient into the interstitial fluid. This contributes to the osmotic gradient and aids water absorption.</em>

Answer:
<em>Animalia is a kingdom which has different phyla. There are thirty six phyla in animal kingdom but nine are the major ones and they are – </em><em>Porifera, Cnidaria, Platyhelminthes, Nematoda, Annelida, Arthropoda, Mollusca, Echinodermata and Chordata. </em>
Explanation:
The organisms are classified on the basis of complexity. The complexity increases with increase in the mentioned phyla.
Humans are the most complex organism that perform several functions. The least evolved phyla is porifera and the most evolved phyla is chordata.
Hi lovely,
The statement above is True.
