Hint:
The epithelium is a type of tissue that lines the body's surface, including the lungs and mouth. Epithelial cells are responsible for creating a protective barrier against bacteria and other invaders. Additionally, epithelial cells secrete digestive enzymes and neurotransmitters, which help to control overall bodily function.
Complete step by step answer:
Epithelial tissue is a kind of cell that covers the outside of the body as well as the inside of some organs. It plays an important role in protecting these surfaces from outside factors, such as bacteria and other invaders. So, option B is not incorrect.
The cell junctions between cells in epithelial tissue are very tight and there is little extracellular material. This helps to keep the adjacent cells separated and protected from damage. However, option C is also not incorrect.
In epithelial tissue, there are no blood vessels to bring nutrients to the epithelial cells. Therefore, option D is also not incorrect.
The statement "Epithelial tissue rests on a cellular basement membrane splitting it from underlying connective tissues" is incorrect. Epithelial cells do not rest on a cellular basement membrane; they are separated from underlying connective tissues by the endothelium.
Option ‘A’ is correct
Note:
Epithelial tissue is an important component of the body's immune system and is responsible for maintaining a healthy barrier between the outside world and your internal organs. This layer of cells lines all surfaces in the body, including the inside of your mouth, nose, throat, stomach, intestines, rectum/anus (backside), vagina/vulva (front side), and skin.
