Connective Tissue

A cell is the basic structural and functional unit of a living organism. A tissue is a group of cells having a common origin, similar structure and function and held together by a cementing substance. Example: Connective Tissue

Animal Tissues

Animal tissues are different and are broadly classified into four types :

  • Epithelial Tissue
  • Connective Tissue
  • Muscular Tissue and
  • Neural \ Nervous Tissue

In this article we are going to discuss about Connective Tissues only.

Connective Tissue

CHARACTERISTICSConsists of a matrix
and the cells are
embedded in it.
LOCATIONFound in the deeper parts of the body in
between the skin and
FUNCTIONConnects various
organs and keeps
them in proper

Types of Connective Tissues

  • Connective tissue proper
  • Supportive connective tissue
  • Fluid connective tissue

Connective tissue proper:

CHARACTERISTICSMade up of irregular cells scattered and
embedded in a soft
LOCATIONEncompasses all the internal organs and
body cavities.
FUNCTIONActs as a binding
and supporting
structure within the

Types of Connective tissue proper:

  • Areolar tissue
  • Adipose tissue
  • Fibrous tissue
Areolar tissue:
CHARACTERISTICSMade of gelatinous
matrix containing
cells and irregularly
arranged fibres.
LOCATIONFound between the
skin and muscles,
around the blood vessels, nerves and in
the bone marrow.
FUNCTIONFills the space inside the organs and supports and
strengthens the
internal organs.
Adipose tissue:
CHARACTERISTICSCells are filled with
fat globules, situated in a large central vacuole of a cell, pushing the cytoplasm and the
nucleus to the
LOCATIONFound beneath the
skin, around the kidneys and other
internal organs such
as intestines.
FUNCTIONActs as an insulator
because of the
storage of energy in
the form of fats. It
insulates the body
and prevents the
loss of heat.
Fibrous tissue:
fibre-forming cells
which form the tendons and ligaments.
LOCATIONFound in the spaces
between the bones and muscles.
FUNCTION1. Tendons help to
attach muscles to
the bones.
2. Ligaments serve to
hold the structures
together and keep
them strong and

Supportive connective tissue:

CHARACTERISTICSHas fibres as its main matrix element.
LOCATIONFound in bones and
connection between
different tissues.

Types of Supportive connective tissue:

  • Cartilage
  • Bone
CHARACTERISTICSNon-porous, semi-transparent and
elastic tissue.
LOCATIONPresent in the nose, external ear, trachea,
larynx, ends of the long bones and between the vertebrae.
FUNCTIONSmoothens the bone surface at joints, allowing smooth movement of these joints.
CHARACTERISTICS1. Hard, strong and
non-flexible porous
2. Consists of living
LOCATIONForms the rigid part of the skeletal system.
FUNCTION1. Forms the
supporting framework of the body.
2. Gives shape and
rigidity to the body.

Fluid connective tissue:

CHARACTERISTICSConsist of fluid/liquid as the ground substance.
throughout the body.
FUNCTION1. Provides nutrition.
2. Helps in transport
of nutrients.
3. Gets rid of waste

Types of Fluid connective tissue:

  • Blood
  • Lymph
CHARACTERISTICS1. Contains a straw-coloured fluid matrix called blood.
2. It consists of
plasma (55%) and
cellular part (45%)
which contains cells, RBCs, WBCs and platelets.
throughout the body
FUNCTIONConnects different
body parts and
establishes continuity within the body.
CHARACTERISTICS1. Fluid surrounding
the body cells.
2. Contains WBCs.
throughout the body.
FUNCTION1. Transportation of
2. Provides protection
against diseases.
