Thank you soo much ❤️

[@mouhammedazeez7664]

You are wonderful,
One thing to ask ,
...angiotensin II constricts the mesangial cells, an effect that tends to lower the GFR by decreasing the surface area available for filtration

[@michealphiri9383]

Thank you very much

[@chetansharma8562]

Beautiful 🥰

[@varathankalimurugan6100]

the video quality and explanation was❤️‍🔥❤️‍🔥❤️‍🔥
can u tell me which app u use

[@Chinnu-je7hr]

Great 👍

[@thegahd]

If there is decreased sodium, it won't want to INCREASE GFR, that would make us just lose even more blood. Low Na+ is a sign of blood loss, and angiotensin II stimulates adrenal cortex to produce aldosterone = more sodium pumps in the distal tubuli

[@shinyvision.]

thank you

[@chithraniweerasingha9916]

Thanks 😊 🎉❤

always d best
