How is epithelial tissue the opposite of connective tissue quizlet?

How is epithelial tissue the opposite of connective tissue quizlet?

How is epithelial tissue the opposite of connective tissue? In epithelial tissue the cells are packed together very tightly. Epithelial tissue is avascular. Epithelial tissue has three cell types that cover or line things and make tubes.

How are epithelial tissues different from connective tissues?

The key difference between epithelium and connective tissue is that epithelium is the tissue that lines outer surfaces of organs and blood vessels as well as inner surfaces of cavities of organs while connective tissue is the tissue that separates, connects and supports various tissues and organs in an animal body.

What is the main difference between epithelial tissue and connective tissue quizlet?

Epithelium protects organs while connective tissue essentially connects organs in some way or another.

What does it mean to be avascular but innervated?

Avascular but innervated. Whereas most tissues in the body are vascular (contain blood vessels), epithelium is avascular (a-vas′ku-lar), meaning it lacks blood vessels. Although blood vessels do not penetrate epithelial sheets, nerve endings do; that is, epithelium is innervated.

How can one tell the difference between stratified squamous epithelium and transitional epithelium quizlet?

The most reliable distinctions are two. Compared to stratified squamous epithelium, transitional epithelium has fewer layers (6 or less) and has more rounded surface cells when it is bunched up with more apparent layers and more likely to be mistaken for stratified squamous.

How are epithelial tissues different?

Epithelial tissues are identified by both the number of layers and the shape of the cells in the upper layers. There are eight basic types of epithelium: six of them are identified based on both the number of cells and their shape; two of them are named by the type of cell (squamous) found in them.

How does connective tissue support epithelial tissue?

As may be obvious from its name, one of the major functions of connective tissue is to connect tissues and organs. Unlike epithelial tissue, which is composed of cells closely packed with little or no extracellular space in between, connective tissue cells are dispersed in a matrix.

How do epithelial and connective tissue work together?

Epithelial tissues act as coverings, controlling the movement of materials across their surface. Connective tissue binds the various parts of the body together, providing support and protection.

Why are epithelial and connective tissues found adjacent to each other?

Epithelial and connective tissues are found adjacent to each other because: Epithelium is avascular and needs to exchange oxygen, nutrients and waste with the blood of highly vascular connective tissue. Which types of cell junctions prevent the contents of organs from leaking into surrounding tissues?

Why is epithelial tissue avascular?

Whereas most tissues in the body are vascular (contain blood vessels), epithelium is avascular (a-vas′ku-lar), meaning it lacks blood vessels. Epithelial cells receive their nutrients from capillaries in the underlying connective tissue.

Where is basement membrane?

The basement membrane is a thin, pliable sheet-like type of extracellular matrix, that provides cell and tissue support and acts as a platform for complex signalling. The basement membrane sits between epithelial tissues including mesothelium and endothelium, and the underlying connective tissue.

How does it differ from other stratified squamous epithelium?

how does it differ structurally from other stratified squamous epithelia? the cells change shape to allow stretching, which are only in the bladder. transitional epithelium is classified as stratified squamous. how does transitional epithelium reflect its function in the body?
