Question

give three difference between epithelial tissue and connective tissue

Answer 1

epithelia

cells bound closely (not seperated by extra cellular materials)



polarity- apical (top) surface usually exposed to the environment/internal chamber



Apical surface lining internal passageways may contain: microvillus and cil



Attach to underlying connective tissue by basement membrane. Connected by hemidesmosomes



Avascular (absence of blood vessels), nutrients diffuse. If cells are damaged of lost at the exposed surface, they are continuously replaced by stem cells at deepest layer

connective

Most diverse tissue in the body



Never exposed to outside environment



Highly vascularized (has many blood vessels)



Has 3 components: specialized cells, protein fibers (located in the extracellular matrix), and has ground substance (fluid) also located in the extra cellular fluid

Answer 2

Cells make up all tissues, tissues make up organs, organs make up systems and systems makeup organisms. Cells have different types that make up different tissues. Each has different characteristics, but the epithelium and connective tissues are commonly confused with each other. To distinguish the differences between the two, below are detailed explanations and descriptions.
