|
The four main kinds of tissue that compose the body’s many organs? |
Epithelial tissue Connective tissue Muscle tissue Nervous tissue |
|
|

|
|
How are epithelial tissues connected? |
Protein connectors in the plasma membrane firmly holds epithelial cells together |
|
|
Does Epithelial cells have interstitial fluid between them? |
they are packed tightly together so they have little to no interstitial fluids |
|
|
Does epithelial tissues have blood cells? If yes, or no please explain why |
No - because they are packed closely together |
|
|
True or false Epithelial tissues have no matrix |
True |
|
|
Where does epithelial tissues get oxygen and nutrients from? |
The blood vessels in the connective tissues |
|
|
Where do you find connective tissues? |
Always underneath sheets of epithelial tissues |
|
|
Describe the basement membrane? |
A gluelike layer that connects the epithelial tissue to its connective foundation |
|
|
Name the shapes of epithelial cells |
Squamous Cuboidal Columnar Transitional |
|
|
Describe squamous epithelial cells |
Flat and scalelike |
|
|
Describe cuboidal epithelial cells |
Cube shaped |
|
|
Describe columnar epithelial cells |
Taller than wide Slender and looks like a rectangular column |
|
|
Describe transitional epithelial cells |
Shape can stretch |
|
|
How are epithelial tissues labeled or arranged |
Simple Stratified |
|
|
A single layer of cells of the same shape |
Simple epithelial tissue |
|
|
True or false Blood plasma always have matrix and fibers, explain your answer |
False - blood plasma always have matrix but does not have fibers - they only have fibers when forming blood clots |
|
|
Describe the fibers in the tissues of your tendon and ligaments |
Dense, strong and twisted in a rope like manner |
|
|
Describe bone matrix fibers |
Encrusted with mineral crystals that gives it a concrete like look |
|
|
Tissues of your tendons and ligaments are thin True or false |
False - they are thick and rope like |
|
|
Name the two types of protein fibers found in the tissue |
Collagen Elastin |
|
|
What is the role of collagen |
Gives the tissues flexibility |
|
|
What is the role of elastin |
Gives you the ability to stretch and rebound easily |
|
|
Describe collagen |
Rope like |
|
|
Describe elastin |
Rubbery |
|
|
Many layers of cells named for the shape of cells in the outer layer |
Stratified epithelial tissue |
|
|
What is the function of the simple squamous epithelium |
Transportation |
|
|
Why can substances pass through the simple squamous epithelium? |
Because it’s a simple layer of thin and irregular shaped cells |
|
|
Where does absorption of oxygen and blood takes place |
In the simple squamous epithelium |
|
|
True or false There are no matrix in epithelial tissues |
False |
|
|
True or false Connective tissues have more matrix than epithelial tissues, explain your answer |
True - because there are more spaces between the cells in connective tissues- in epithelial tissues the cells are packed closely together therefore they have less matrix |
|
|
Another name for matrix |
Extra cellular matrix |
|
|
Describe matrix |
Fluid like material between cells that’s holds them together Jelly made up of mostly water with fibers that thickens it |
|
|
Are there any matrix in blood plasma? |
Yes |
|
|
Name the types of epithelium |
Simple squamous epithelium Stratified squamous epithelium |
|
|
Closely packed epithelium |
Stratified epithelium |
|
|
The epithelium that is arranged to protect the body from invasion of microorganisms |
Stratified squamous epithelium |
|
|
Microbes can enter the body through mucous membranes, explain your answer. True or false |
False - skin, tears and mucus are part of the first line of defense in fighting infections- they protect against invading pathogens |
|
|
What is the function of the simple cuboidal epithelium |
Secretion |
|
|
The tissue that forms tubules |
Simple cuboidal epithelium |
|
|
If you looked at a group of cells how can you know it’s a simple cuboidal epithelium |
They join together to form rings and the inner part of the rings forms the tubes |
|
Give the name of these cells and state why they form in a ring like shape |
Cuboidal shape Why? They form in a ring to create tubes for secretion They make up the simple cuboidal epithelium |
|
|
Another name for secretory cells |
Glands |
|
|
Name the classification of glands |
Exocrine Endocrine |
|
What cells are found in this gland? Why is this gland formed in this way? |
Cuboidal cells forming the wall of the gland It is form in a tubular form for secretion |
|
|
What does exocrine glands do? |
Release secretions through a duct |
|
|
What does the endocrine glands do? |
Release secretions directly by diffusion into the blood stream |

|
What gland secretes harmonies? |
Pituitary gland Thyroid gland |
|
|
Tubules that forms urine in the kidneys |
