What do you notice is the main difference between the structure of the connective tissues and the structure of the epithelium? m
AVprozaik [17]

Epithelial tissue lines the cavities and surfaces of organs and blood arteries throughout the animal body, whereas connective tissue supports, links, and divides many types of tissues and organs in the body. This is the main distinction between epithelial and connective tissue.

Cell arrangement: The physical properties of the Epithelial tissue affect how the connective tissue is organized. There are different arrangements of epithelial cells, such as squamous, cuboidal, and columnar, that organize as simple, stratified, pseudostratified, and transitional. Since epithelial cells form from ectoderm, mesoderm, and endoderm, this explains why epithelia line body cavities. Dense irregular connecting tissue is made up of messily organized tightly packed collagen bundles.
