Differences between connective and epithelial tissuse
Answers
Answer:
The main difference between epithelial tissue and connective tissue is their function and the cells they are comprised of. Epithelial tissue consists of three cell types; squamous, cuboidal and columnar. ... Connective tissue supports, connects, binds, or separates other tissues or organs
Explanation:
BASIS FOR COMPARISON EPITHELIAL TISSUE CONNECTIVE TISSUE
Made up of Cells and small amount of intercellular matrix. Cells and a huge amount of intercellular matrix
Role 1.Mainly forms covering of the organs, internally and externally.
2.Helps in transcellular or intercellular transportation.
3.In selective absorption, protection of cells. 1.Support and anchors other tissue and organs.
2.Helps in muscles and bone formation.
3.Also helps in working of blood and lymph.
Develops from It develops from the endoderm or mesoderm or ectoderm from the embryological germ layer. Develops from mesoderm (embryonic mesodermal origin).
Arrangement These cells are arranged in layers which can be either single or multi layer. Here cells are present in scattered form in the matrix and does not show any arrangement.
Surrounded by Does not surrounded by blood capillaries. These cells are surrounded by blood capillaries.
Location These tissues lie above the basement membrane. These tissues lie below basement membrane, called lamina propia.
Nutrition As epithelial cells are not bounded by blood capillaries and they gain their nutrition from the cellular membrane. These types are bounded by blood capillaries and hence gain nutrition from there.
Bounded by Special proteins, desmosomes and hemidesomes. Blood capillaries and materials like elastic or collagen fibres.
Can be found Lungs, kidneys, skin, mucous membranes. Bones, nerves, ligaments, tendons, blood.
The epithelial tissue forms a continuous layer over the free surface of many other tissues. Consequently, it covers the external surface of the animal body and the internal surfaces of visceral organs, body cavities and blood vessels.
While the Connective tissue provides the structural framework and mechanical support to different tissues forming an organ. It also plays a key role in the body defence, tissue repair, fat storage and transmission of blood vessels to the other tissues.
