(14:47-28:35) Mechanisms of concentration and dilution of urine: 1-Medullary Interstitial Hyperosmolarity (MIH) [Cortico-Papillary Osmolar Gradient]; outline of its mechanism of production and maintenance. 2-Role of ADH as the second mechanism of concentration & dilution of urine. (28:36-54:50) Mechanisms of concentration and dilution of urine continued: 1-Development of Medullary Interstitial Hyperosmolarity (MIH); Counter Current Multiplication Mechanism. (54:51-1:03:26) Development of MIH continued; Urea Recycling in Renal Medulla. (1:03:27-1:10:47) Maintenance of Medullary Interstitial Hyperosmolarity (MIH); Vasa Recta's Counter Current Exchange Mechanism/System. Comparison of Counter Current Multiplier & Counter Current Exchanger System. (1:10:50-1:28:55) Mechanisms of concentration & dilution of urine continued: 2-Role of Anti Diuretic Hormone (ADH); enhancing water permeability in last part of nephron. (1:28:56-1:47:40) Recapping the concept of concentration & dilution of urine with the help of an example of a person's thirst and water intake in differing environments; emphasis on effects of ADH on the nephron. (1:47:41-1:57:57) Explanation of "Ratio of Tubular Fluid Osmolarity (TF) to Plasma Osmolarity (Posm)" at different points along the nephron; emphasis on the role of ADH. --------------------------------------------------------------------------------------------------------------------------- Join this channel to get access to perks: Sign up now on our website at https://members.drnajeeblectures.com/...    / @doctornajeeb   Follow us on Facebook :-   / drnajeeb   Follow us on Instagram :-   / drnajeeblectures
