The kidneys are an integrative system that continuously interacts with the cardiac, endocrine and practically all of systems in our body, and that in addition the kidneys function in several capacities. As excretory organs, the kidneys ensure that those substances in excess or that are harmful are excreted in urine in appropriate amounts. As regulatory organs, the kidneys maintain a constant volume and composition of the body fluids by varying the excretion of solutes and water. Finally, as endocrine organs, the kidneys synthesize and secrete three hormones: renin, erythropoietin, and 1,25-dihydroxycholecalciferol.

In these conferences we will understand the importance of body fluids, the maintenance of ionic composition and osmolality in our body. We will understand how the nephron works, the functional unit of the kidneys, with emphasis on the mechanisms starting in the glomerulus to the collecting duct. We will also cover the mechanisms of ion and water movement that occur in each of the nephron segments. Also, we will discuss the maintenance of the acid-base balance, its origins and compensation (if exist). We will use common application cases in clinical practice.

Throughout this theme, in this particular year (2021), in addition to remote synchronous interactions, clinical case discussions, formative questions, and small group interactions will be used. I would appreciate any suggestions to help improve the presentation.
