@InteractiveBiology THANK YOU!!! for the great community service, your time, efforts and talent for teaching is much appreciated!!!
Id really appreciate it if you could make videos about pulmonary oedemas and cardiac arrhythmias I really need help understanding those concepts You seem to make concepts very clear and I really enjoy the way you explain things
This video did not load from the interactive website. Possibly because the URL was ht tp"v"... I removed the "v", and was able to view it here on you tube. You rock. Thanks for the free schooling.
@madej1858 All questions are answered in the Interactive Biology community forums from now on. Go to the website in the description and then visit the community. This is to make it as efficient as possible as we have multiple people over there to help answer questions. All the best
Since some of your video helped with exam 2, I am going to be watching your videos from now on :) They are very helpful! We're doing blood and Lymph system next.
This video really helped with some of the exam questions. There was question saying that PR increases __when viscosity increases (I chose this) I thought of this video and got it. I also remembered how to calculate MAP 'cause of this video. Thanks a lot! I got myself 6 points because of this. I would probably have chosen different answers. I think I got around 80-82 for this exam. My teacher said it is the hardest exams ever. I really hope I got around 80-82
ooooh I always wondered why McDonalds milkshakes were impossible to drink!! I havent had one since I was about 11 cos they are too thick!! It also explains how in the cool hawiian bar here, with the really long straws for their crazy volcano themed cocktails... its reallly difficult to drink your cocktail... but I didnt stop going there of course!! I once again feel enlightened after watching your videos... and its given me an extra incentive to resist the icecream this summer too !!
it's so nice, i love this video.
Soo helpful thanks so much
thank you so much for all you do!

that's what she said
"it was hard to get it in my mouth because of how THICK!! it was..." haha
if PR goes up for dehydrated then MAP pressure will go down?
I love you Leslie Samuel! xx

ok
if the PR goes up, then MAP goes up as well. they are directly related.
Wow ..
where is the 2.2 lbs fat = 400 miles statistic from???
then gain muscle weight!
Wow , i need to lose weight :(
