Excretory System and the Nephron

Join the Amoeba Sisters as they explore the excretory system! This video will first discuss two major functions of the excretory system before focusing on the nephron. The majority of this video will tour through the nephron while listing major items reabsorbed and secreted.

[@margaretagyei3376]

No

[@rafsanjani7819]

I just love the way she made it look like a piece of cake yet gave a detailed explanation which helps me remember. And yes, the video explains much better than my science teacher.

[@AlecHutson-op8dn]

I cannot express in words how thankful I am to you guys for making these videos. I would have zero chance in my bio class if it weren’t for you.

[@StaticBlaster]

It's been a while since you've uploaded. So, it's great to see a video from you. :)

[@maryambatool6986]

[@ssm188]

all the best! you got this!

[@mingyue_chen]

Is it just me or is this video so much more detailed than those of the other systems?

[@unmep2528]

Well, at the start of the video she did say that the excretory system is the most ignored, and in fact, the most important system that not many people are that familiar with. Maybe the amoeba sisters are biased? LOL.

[@vanshikahariya7144]

You guys made it so easy. Thank You so much ❤ . You have no idea how badly I was struggling to remember this portion

[@AmeAttire]

I have no clue what girlys on abt. I understood the first 2 mins but got lost at the nephrons 🙂

[@10Th1ngs]

Thanks Amoeba sisters♥️♥️♥️🥰🤩

[@MicrowaveOvenVideo]

1:57 & 8:09 Just one little nitpick. The ureters loop behind and under the bladder, filling from below. This is because having the urine fall into the bladder would be taxing having a constant drip of liquid as well as unneeded stimulation of the nerves.

[@natarajanrd]

This was a fun and informative video

[@dweebteambuilderjones7627]

Your characters are frequently hilarious, and this video was a great showcase of them. "WE DEMAND *ALL* THE SALT!" - Aldosterone, probably.

[@khepri5945]

Please fix the video :( Some of the illustrations are hard to see with the captions on top. These have been so helpful for my K103 studying. Thank you!

[@kartiktotlani]

I really wish KZbin and this channel existed while I was choosing a career

[@W4VDragon]

Amazing explanation

[@Jireh.s]

Who is here the morning of the exam

[@bridgeythecommie]

omg the always sunny reference at the end yesss

[@unknownpitch]

Please sister Make videos on Aldosterone and ADH if possible.

[@kenziebacklin11]

Id like to see a video by u guys on kidney failure as well
