So if we're looking at our answer choices, you start with a, epithelial, b, connective tissue, c muscle, and d nerve.
00:15
If we look at the functions for each of these tissue types, epithelial cells mainly create a barrier so substances can't get through.
00:25
And for substances that can passively diffuse through a cellular membrane, they're allowed to selectively be transported across that way.
00:33
Layer.
00:35
Connective tissue are basically what holds together one tissue to the next.
00:40
So in the case of skin, we have a bottom adipose layer.
00:45
We have a top epithelial layer to keep things from getting through.
00:49
And in between, we have that connective layer of tissue that basically holds the skin together.
00:55
One layer to the next.
00:57
Muscle tissue is a series of cells that work together to lengthen and shorten muscles.
01:05
They're going to stretch according to electrical signals applied on them, and they're what give us our ability to move and function.
01:15
Nervous tissue are what feed those electrical signals.
01:19
For the most part, these are singular bodies, one nerve giving one kind of signal to one type of cell...
