Tissues
1) Based
on the shape and function of its cells, epithelial tissue is subdivided further
into squamous, cuboidal, columnar, ciliated and glandular.

Ciliated
|
Cubical or columnar cells with
cilia.
|
Moving
materials, like mucus, forward.
|
Glandular
|
Glands
formed from cuboidal or columnar cells.

Secretion

2)
Connective
tissue is the binding and supporting tissue of the animal body. Matrix forms
the main bulk of this tissue, whereas the cells are loosely spaced and less in
number.
3)
Blood,
bone, ligament, tendon, cartilage, areolar tissue and adipose tissue are
important connective tissues present in our body.
4)
Blood
is a fluid connective tissue, composed of plasma and cells, and plays a
significant role in the process of transportation.
5)
Functions
of protection, providing skeletal framework and anchoring are carried out by
the strong and hard bone tissue.
6)
Ligaments
connect bones to bones whereas tendons connect bones to muscles.
7)
Cartilage
provides support and flexibility to the body parts.
8)
Areolar
tissue repairs the injured tissues and fills spaces within organs.
9)
Adipose
tissue serves as a fat reservoir and also carries out the function of
insulation.
10)
All
movements in our body are brought about by the muscular tissue through the
contraction and relaxation of their contractile proteins.
