describe simple Squamous epithelium
function of simple Squamous epithelium
diffusion and filtration
location of simple Squamous epithelium
pulmonary alveoli, kidneys, lining the inner walls of blood and lymphatic vessels (endothelium), form serous membranes that line the body cavities and its organs – pericardium, pleura, peritoneum
describe simple cuboidal epithelium
FUNCTION of simple cuboidal epithelium
secretion, filtration and absorption
LOCATION of simple cuboidal epithelium
found in many glands and glandular organs and ducts (e.g. surface of ovaries, ducts of salivary glands and pancreas)
describe simple columnar epithelium
what are the two types of simple columnar epithelium
ciliated
non-ciliated
what is non-ciliated simple columnar epithelium covered in and why
covered in microvilli to increase SA for absorption in intestine
what is ciliated simple columnar epithelium covered in and why
covered in cilia to support beating of secondary oocyte through the uterine tube to the uterus)
function of simple columnar epithelium
protection, lubrication, secretion and absorption
location of simple columnar epithelium
lining of intestine, uterine tubes, bronchioles
describe pseudo-stratified simple epithelium
what are the two types of pseudo-stratified simple epithelium
non-ciliated
ciliated
function ciliated Pseudo-stratified simple epithelium
ciliated= protection, secretion of mucin, movement of particles and mucus
function non-ciliated Pseudo-stratified simple epithelium
protection
location of ciliated pseudo-stratified simple epithelium
ciliated: trachea, bronchi, nasal cavity
location of non-ciliated pseudo-stratified simple epithelium
non-ciliated: male urethra, male epididymis (sits on top of testes, where sperm matures)
describe stratified Squamous epithelium
function of stratified Squamous epithelium
found in areas subjected to wear and tear; top layer cells are rubbed away and replaced via mitosis of the innermost cells
what are the two types of of stratified Squamous epithelium
keratinised
non-keratinised
location of keratinised stratified Squamous epithelium
keratinised (dry) contains keratin, a protein that strengthens the tissue, LOCATION: epidermis
location of non-keratinised stratified Squamous epithelium
non-keratinised (wet) mucosa; LOCATION: mouth, oesophagus, larynx, vagina, anal canal
describe stratified cuboidal epithelium
- usually only two or three layers of cuboidal cells
