Tissues Flashcards
1
Q
What is the structure of epithelial tissue?
A
- one free surface
- tightly packed cells
- very little extracellular material
- a lack of blood vessels
- anchored to the underlying connective tissues by a thin extracellular structure called the basement membrane
2
Q
Where is epithelial tissue located?
A
- covering of the boys surface
- lining the body’s cavity
- covering the internal organs
- lining the internal organs
- composing glands
3
Q
What are the functions of epithelial tissue?
A
- protection
- secretion
- absorption
- excretion
- sensory reception
4
Q
What are the 3 shapes of the epithelial cells?
A
- squamous: thin and flat
- cuboidal: cube shaped
- columnar: tall column shaped
5
Q
What are the cells of epithelial tissues arranged in?
A
- simple epithelium: a single layer of cells
- pseudostratified epithelium: appears to have several laters of cells because the cell nuclei lie at different levels but actually only has a single layer of cells
- stratified epithelium: consists of 2 or more layers of cells
6
Q
What is the structure of connective tissue?
A
- widely spaced cells
- abundant extracellular matrix
- good blood supply
7
Q
Where is connective tissue located?
A
wide distribution in the body
8
Q
What is the function of connective tissue?
A
transportation of nutrients, wastes and gases production of blood cells fat storage protection against infection binding structures providing support serving as a framework protection and insulation of internal organs
9
Q
What are the two major cell types found in connective tissue?
A
fibroblasts: the most numerous type of cell found in connective tissue, they secrete protein fibres and ground substance
macrophages: engulf bacteria and cell debris by phagocytosis
