In this question we have to describe the three tunics of gallbladder.
00:05
So tunics are basically the walls of gallbladder and gallbladder is the organ which is connected with the liver and its main function is to store bile juice.
00:16
It stores the bile juice which is then secreted into the small intestine.
00:20
So gallbladder is basically made up of three layers.
00:23
The innermost layer is the mucosa.
00:26
So mucosa is the innermost layer and mucosa is itself composed of three different layers.
00:35
The innermost layer of the mucosa is the epithelium.
00:40
So epithelium is basically a single single layer and it is composed of columnar epithelium cells.
00:48
Columnar epithelium cells and these cells they basically absorb the water and ions from the bile.
00:58
So they absorb water and ions from the bile which is stored inside the gallbladder as we discussed and when it absorbs water and ions basically it will concentrate the bile.
01:16
It will concentrate the bile and convert it into a more concentrated juice.
01:21
Secondly we have outside to the epithelium the lamina propria.
01:27
So for the second layer is lamina propria and this layer basically consists of connective tissue.
01:35
It consists of connective tissue and this connective tissue is supplied with all the blood vessels and all the lymphatic vessels.
01:44
So it is supplied with the blood vessels and the nerves...
