My professor lectured everything in section, which makes me super confused and felt disorganized. It's great to have this general overview of the function of the nephron. Really appreciate this, highly recommend to anyone who are struggling with kidney physiology.

[@Jane-167]

I'm a hs senior year student in Turkey, and I just wanted to say that, the way you explain it is much detailed and therefore clearer for me to understand what exactly is going on. No one teaches this system with this much explanation in Turkish sadly. I'm so glad that I finally understand biology because of you ❤️

The vasa recta are only in the juxtamedullary nephrons, reaching deep down into the renal medulla. The cortical nephrons only have peritubular capillaries.

[@krystallowe1810]

Thanks for confirming this is true! I doubted myself a little when he was calling it vasa recta lol.

I found this video to be super interesting. But if you had an exam on nephrology, how much of this content would be on an exam?

[@jseanbrooks1]

@@Zux78 I'm looking through his nephrology videos to review for A & P and we are covering all of this plus a vast array of other info on the urinary system, I think the biggest thing missing in my class that he covered is the chemical reactions side of things. Pretty sure he's graduated med school so med school exams or MCAT is where the chemistry side of this would be likely to have the most prevalence I'd imagine.

Great review. The nephron is incredible. As a RRT, I understand acid/base balance: metabolic alkalosis/acidosis and respiratory alkalosis/acidosis. The renal and respiratory systems work hand-in-hand to balance pH. This information is so important; because, it the basis for understanding ABG's and the consequences of abnormal ABG results. Thanx for the great presentation.

[@Soneoak]

I know this video is old and your knowledge has probably updated since, so this comment is for new people seeing. The way the bicarbonate ions is absorbed without being acidic is wrongly described here. CO2 and water can equilibrate into bicarbonate ion and hydrogen ion. As the HCO3- is a molecule that can receive H+ ion, it acts as a conjugate base. When conjugated with h+ in the form of H2CO3, it is carbonic acid. Carbonic acid can requiliberate into co2 and h20. There are 2 equilibrium phases here. When sodium is reabsorbed, it creates an electric imbalance of positive ions. What happens is to balance it, we need to get rid of an equivalent positive ion, or pick up a negative ion. Sodium is usually with chloride ions as both are strong ionic molecules (atoms in this case), but if chloride ions are not reabsorbed, then it will also have to be balanced with a positive charge to go with it. The kidneys have devised a way to chuck out a positive charge “molecule” and keep a negative charge molecule at the same time that does not really require a special transporter or any energy, just a buffer that can change arround easily. That is the hydrogen ion, and bicarbonate molecule. It chucks out a h+ to keep the Cl- happy, and keeps a hco3- to keep the na+ happy. This is a very nuanced principle, but is key to understanding what to remember and what is going to be confusing. Example - the chloride transporter in the distal convoluted tubule and collecting duct, is not a hco3 ‘transporter’, it merely uses the balanced negative charge to reduce electrical work required to get it excreted. Movement of the chloride ion is more important than movement of the bicarbonate ion as the bicarbonate ion can just change into CO2, move across and change back. The reality is, when Cl move in, and hco3 move out, it’s practically the same as a h+ moving in with the cl-. So hcl moved in if the balancing ion is hco3-. If not, then work has to be done against an electrochemical gradient.

[@MarkoGangur]

Video is really helpful, but you can't say that ions from PCT, DCT and CCT go to vasa recta, since PCT, DCT and CCT are in cortex, and vasa recta is in medulla. If PCT, DCT and CCT were in medulla all the reabsortion of ions and water would disturb hiperosmolarty of medulla which is balanced by function of vasa recta (cunterurrent exchanger). Kidneys would be then spending a lots of energy to make again and again hiperosmolarty of medulla so they could concentrate urine. Accurate would be if you wrote that ions and water from PCT, DCT and CCT go to peritubular capillaries.

There is also H+-ATPase and H+/K+-ATPase in the distal and collecting tubules. This way H+ is excreted by primary active transport compared to the secondary active transport in the early tubular segments which is Na+-dependent.

Thank you so much for making this kinds of videos i love your videos and explaination you made for us

[@aba9119]

I found it confusing. The diagram at 2:31 shows blood entering the glomerulus and exiting via the efferent arteriole. You don't explain how blood comes to flow down PCT or why it does so. You list a bunch of ions that are leaving the PCT, but why are they doing so? What is drawing them out? Also, reabsorption into what? (2:36). I feel like a lot of the conceptual heavy-lifting was ignored, so the video does a good job of simply describing what is going on, and I took some notes, but the explanatory power was limited by the faults I've highlighted above.

[@raahul1303]

1.efferent arteriole continues wrapping around the nephron forming vasa recta 2. the ions are reabsorbed because they move down their conc gradient via a symporter which also transports amino acids and glucose, they are absorbed into the cuboidal cells of the pct wall then into vasa recta surrounding it He's mentioned all this rather in a subtle manner, youre expected to know the histology of nephron before watvhing the reabsorption video there are following steps filtration reabsorption secretion excretion he has only covered reabsorption, watch it again
