Let's start reviewing for the test!!

Hi, people!!! Ideal rainy day for a post!  I´ve been surfing the net to find some videos that can help you understand the relationship between surface area and volume. This is a key concept to understand absorption in every part of our bodies.
So, less talking and more doing!!! In the first video, a Biology teacher explains why cells are so small



We saw this video in class about the implications of the surface area to volume ratio (=proporción) in cells



This is an interesting video to review the mecanisms of transport of substances IN and OUT the cells




To review ENZYMES


If you need material to review DIGESTIVE SYSTEM, there you go!
