|
A group of cells that have specialized structural and functional roles are called what?
|
Tissue
|
|
|
What are the four types of tissue?
|
Epithelia
Connective Muscle Nervous |
|
|
Which type of tissue is most exposed?
|
Epithelial
|
|
|
Where are epithelial tissues found? (3)
|
Covering organs
Inner lining of body cavities Lines of hollow organs |
|
|
Is epithelial tissue lightly packed or loosely packed
|
Tightly
|
|
|
What do epithelial tissues lack that has to do with getting nutrients?
|
Blood vessels
|
|
|
How does epithelial tissue get nutrients?
|
Able to diffuse through underlying tissue
|
|
|
Do epithelial tissue divide fast?
|
Yes, faster than any other tissue
|
|
|
What is the main function of epithelial tissue?
|
Be a protective barrier
|
|
|
What is the second function of epithelial tissue?
|
Secretion, absorption
|
|
|
What type of epithelial tissue is a single layer of flattened cells fit tightly together?
|
Simple squamous
|
|
|
Is simple squamous easily damaged?
|
Yes
|
|
|
Simple squamous tissue very effective at sites of _____
|
Diffusion
|
|
|
Which kind of tissue is found lining air sacs in lungs and lining blood vessels
|
Simple squamous tissue
|
|
|
Where is simple cuboital found?
|
Covers some glands
|
|
|
What is the function of simple cuboital?
|
Secretion or creates hormones
|
|
|
Which type of epithelial tissue creates the thickest layer?
|
Simple columnar
|
|
|
Where is simple columnar found? And why
|
Stomach, intestines, needs to be thick enough for protection, but thin enough for absorption
|
|
|
What is function of simple columnar?
|
Protection, usually secretes mucus
|
|
|
What type of epithelial tissue looks like multiple layers but is only one?
|
Pseudostratified columnar
|
|
|
Which type of epithelial tissue has cilia
|
Pseudostratified columnar
|
|
|
Where is pseudostratified columnar found? And why
|
Line respiratory system, because cilia can catch things
|
|
|
What type of epithelial tissue has many layers of flattened cells that replicate quickly?
|
Stratified squamous
|
|
|
Where is stratified squamous found?
|
Lining outer layer of skin
|
|
|
Which type of tissue is two or three layers, covers glands
|
Stratified cuboital
|
|
|
Where is stratified columnar found?
|
In reproductive tract
|
|
|
What is the function of stratified columnar?
|
Secretion, protection, get egg and sperm where they need to go
|
|
|
Which type of tissue is found lining the air sacs in lungs, lining inside of blood vessels? Why
|
Simple squamous, (its very effective for diffusion)
|
|
|
What kind of tissue do you find covering some glands? Why?
|
Simple cuboital, function is secretion (salvitory glands, thyroid follicles, kidney tubules)
|
|
|
What type of epithelial tissue is found in the stomach and intestines? Why?
|
Simple columnar (need to be thick enough for protection but thin enough for asorption)
|
|
|
Which type of tissue is found lining the respiratory system? Ey?
|
Pseudostratified columnar, (cilia catch things that arent supposed to go down lungs)
|
|
|
Which type of tissue forms outer layer of skin? Why?
|
Stratified squamous (strat. Squam replicates quickly)
|
|
|
Which type of tissue is found covering some glands? And has more than one layer?
|
Stratified cuboital
|
|
|
Which type of tissue is found in reproductive tract? Why?
|
Stratified columnar (secretion, protection)
|
|
|
Which type of epithelial tissue is the best for diffusion
|
Simple squamous
|
|
|
Which type of tissue divides the fastest
|
Epithelial (stratified squamous)
|
