Animal tissues
Epithelial tissues
stratified squamous
layered simple squamous
columnar epithelial
absorption/secretion happen
pillar like
hair like projections present (cilia)
inner lining of intestine
simple squamous
thin/flat/form delicate lining
lining of mouth
cuboidal epithelium
cube shaped cells
provides mechanical support
forms lining of kidney tubules/ducts of salivary glands
Connective tissues
Bone
supports main organs/non flexible
Ligament
connects 2 bones to each other
elastic
Blood
plasma
