Where are simple squamos cells found? |
In the kidney glomeruli; the air sacs of the lungs; the lining of the heart, blood vessels, and lymphatic vessels; the lining of the ventral body cavity (serosae). |
|
|
What is the function of simple squamos cells? |
Diffusion and filtration where protection not important. Secretes lubricating substances in the serosae. |
|
|
Where are stratified squamos cells found? |
If nonkeratinized, found in moist linings of esophagus, mouth, vagina, urethra, anus. If keratinized, it forms the epidermis of the skin, a dry membrane. |
|
|
What is the function of stratified squamos cells? |
Protect underlying tissues in areas subject to abrasion. |
|
|
Where are simple cuboidal cells found? |
In the kidney tubules; the ducts and secretory portions of small glands; ovary surfaces. |
|
|
What is the function of simple cuboidal cells? |
Secretion and absorption. |
|
|
Where are stratified cuboidal cells found? |
Largest ducts of the sweat glands, mammary glands, and salivary glands. |
|
|
What is the function of stratified cuboidal cells? |
Protection. |
|
|
Where are simple columnar cells found? |
For the non-ciliated part, most of the digestive tract (stomach to anal canal), gallbladder, excretory ducts of some glands. For ciliated, lines the small bronchi, uterine tubes, some regions of the uterus. |
|
|
What is the function of simple columnar cells? |
Absorption; secretion of mucus, enzymes, other substances. Ciliated kind propels mucus (or reproductive cells) by ciliary action. |
|
|
Where are pseudostratified ciliated columnar cells found? |
The non-ciliated are found in male's sperm-carrying ducts and ducts of large glands. Ciliated line the trachea, most of the upper respiratory tract. |
|
|
What is the function of pseudostratified ciliated columnar cells? |
Secretion, particularly of mucus; propulsion of mucus by ciliary action. |
|
|
Where are stratified columnar cells found? |
Rare, but small amounts in the male urethra and in large ducts of some glads. |
|
|
What is the function of stratified columnar cells? |
Protection, secretion. |
|
|
Where are transitional epithelial cells found? |
Lines the ureters, bladder, and part of the urethra. |
|
|
What is the function of transitional epithelial cells? |
Stretches readily and permits distension of urinary organ by contained urine. |
