With regard to human body, there are two important components which define the human body.
00:06
The first one are the blood vessels because these are the tubes that will supply the oxygen -rich blood and collect the oxygen -poor blood from different parts of the body.
00:18
And next to blood vessels is the epithelium because these epithelium will form the protective layers and also other important function like secretory function layers in different.
00:30
Parts of the body.
00:31
Both of these tissues are made up of three important layers.
00:36
The first one, it is called as the tunica intima.
00:42
And next one, it is called us the tunica media.
00:46
The third one, it is called us the tunica external or tunica adventia.
00:52
So these are the three different types of layers which will form a protective covering for these tissues itself.
01:01
As they also have some certain functions, they need to be protected as well.
01:05
So these layers help in protecting these by making them function regularly.
01:11
As the name intima states, it is the innermost layer that can be seen either with regard to the blood vessels or the epithelium...
