Dr. Najeeb you have helped me so much. I am studying to be a Paramedic and your videos will get me through the course with no problems. Thank you, much appreciated!
even if my english is not perfect, it´s still the best source of physiology info I´ve ever found. It sounds so clearly and simple, next to a few diagrams, which made our professor.. Thanks so much from Czech republic
OMGosh! You're explanations are so easy to understand. Love the "mango" explanation. I now understand a lot more of how renin is produced by the reduction in blood pressure!! Thank You, this will help me so much in my Nursing Exams. Very much appreciated
Thank you for your love and support. :) May you be blessed with knowledge, prosperity, love and happiness, always. We wish you success and happiness in every walk of life and good luck in your future endeavors. Regards, Dr. Najeeb Team
This video has been soooo educational and entertaining. I'm watching just before taking my comprehensive final and wish I had found it earlier. So helpful and easy to comprehend information that I could NOT seem to grasp before. Thank you. :)
You are amazing!!! You might have just reignited my passion for learning and for medicine and for kidneys especially (LOVE them!!!). Simply amazing. Your passion is contagious. Thank you.
Oh man! I was SCREAMING out JGA! JGA! JGA! This guy rocks. I wish I could skip the thousands of dollars of debt from college, pay a few hundred for a comprehensive list of videos like this, and end up with a BETTER education. Seriously.

Most of the Sodium is reabsorbed in the kidney tubules. There are Sodium sensing cells called as macula densa lining the tubule at the junction of DCT and thick Loop of Henle. Special muscle cells ling the afferent arteriole is called Juxtaglomerular Granular Cells. These cells lie between macula densa and Polkissen cells Together, the Polkissen cells, JG cells and macula densa constitute JG(Juxtaglomerular apparatus).They produce Renin. When there is blood loss, renal perfusion is less. And movement of fluid through the tubule is slow. So there is more Sodium is absorbed. So less sodium comes to macula densa. Macula densa produces NO which activates JG cells and JG cells produce major proportion of renin. Whenever Blood pressure falls down, like during blood loss, carotid sinus signals CNS
