-
1 excretion
2 secretion
3 support
4 protection
5 transport
6 reproduction
7 absorption
8 lubrication - Describe a simple squamous epithelia, its function and where you would find it
-
Flattened centered nucleui is disc shaped, one layer, scalelike sparse cytoplasm.
Function absorbtion, filtration.
It is found in the kidneys, in lining of blood vessels(endothelium), lungs, lymph lining - Name the 4 types of tissues
- Epithelium, connective, muscle, & Nerve
- What is the funtion of Mitochrondia?
- It produces ATP also call the "powerhouse of the cell"
- What is the function of Peroxisome
- Detoxifies harmful chemical, alcohol, hydrogen peroxide ect..
- What is the function of Lysosomes?
- Lysosomes digest wornout cell organelles (stomach breakdown of food)
- What is the funcion of Golgi apparatus?
- Role in packaging proteins & lysosomal enzymes
- What is the function of smooth endoplasmic reticulum?
- Lipid synthesis & metabolism & drug detoxification
- What is the function of rough endoplasmic reticulum?
- Stores & transports proteins
- Function of ribosomes
- Actually site of protein synthesis
- Function of centrioles?
-
Directs the formation of mitotic spindle during cell division
form the bases of cilia & flagella - Describe stratified squamous epithelium, location and function
-
Thick membrane several layers, basal cells cuboidalor, columnar & metabolically active surface squamous.
Function protects underlying tissues in area subjected to abrasion.
Found nonkeratinized types: lining of mouth, vagina, esophagus
Keratinized type: epidermis of the skin, a dry membrane - Describe transitional epithelium, function, location
-
Layers of cell which change their shape when they are distended.
Function stretches
location Bladder, lining of ureters, part of urethra - Describe pseudostratified columnar epithelium
-
(false/two layer)
Single layer differing heights some not reaching surface
function secretion, particularly mucus cilia propels mucus
found nonciliated types: male's sperm
ciliated types trachea, most upper respiratory tract - Descibe simple cuboidal epithelium, location, function
-
single layer cube like shape with large centered spherical nuclei
funtion secretion & absorbtion
location: kidney tubules, thryoid gland, surface of ovary - Describe simple columnar epithelium, function, location
-
Tall single layer with oval nuclei may contain cilia
Location: stomach, intestine, uterus, uterine tubes
function absorbtion, secretion fo mucus, enzymes, cilia propels mucus
