    OMG!!!! I only have a few more weeks of Human Anatomy and Physiology II and I am so MAD I just found you!!! You were here when I started Anatomy I and I didn't even know it. You have such a flow and easy way to follow each body system etc., Although I am just so mad I missed you for so long, thank you for being here now at least! THANK YOU!!!!

    Studying for the MCAT makes you feel like you can never spend too long on one thing. I didn't really fully get the RAAS from a couple of videos I watched but figured I'd just wing it with the knowledge I had. Finally decided I really needed to get it down and this is the first time it actually stuck with me. Thanks a million man.

    I have been self-studying my A&P II course based on just the textbook and my professor’s ppt slides because the lecture weren’t helpful. If you were to be my professor, my A&P II course would be so much better and easier to learn, especially for someone like me who is a visual learner. These picture illustrations and side by side explanations are amazing!

    Angiotensin II has an effect on both afferent and efferent arteriole but it mainly constricts the efferent to maintain the GFR.

    Hey I have a question, wouldnt vasoconstriction of afferent arteriole decrease blood flow into glomerulus therefore decreasing pressure, which would decrease GFR which is a good thing because we have a low blood volume so we want to keep as much volume within the blood

    Thank you!!- quick question, since you mention that this system is about low levels of Na+ if there was a high intake of sodium by the human, like eating salty meals- would this system cease? as in stop the stimulation of aldosterone to prevent reabsorption of Na+ into the blood stream and allow it for secrection into the urinary system.
