Answer 2

Answer:

Explanation:

➺ Connective tissues are the most widely distributed and abundant tissue found in animals.

➺ It connects different tissues or organs and provides support to various structures of the body.

➺ Conective tissues are broadly classified into proper connective tissue, skeletal connective tissue and vascular connective tissue.

Proper Connective Tissue:

➣ It is again divided into loose, dense and specialised connective tissue.

Loose connective tissue:

• It consist of cells and fibres which are loosely arranged in a semi fluid matrix.
• Areolar connective tissue: The matrix is made up of modified polysaccharides and glycoproteins.Fibroblasts, mast cells, plasma cells,macrophages are scattered in the matrix. It is present beneath the skin, around blood vessels, in the sub mucosa of gastrointestinal tract. It provides support and elasticity between organs. It also facilitates migration of cells at the site of inflammation.
• Adipose connective tissue: It is also called as fatty connective tissue. The adipose cells are called as adipocytes.  It is present beneath the skin and around the kidneys and heart. It provides insulation, stores excess fat and also helps in shock absorption.

Dense connective tissue:

• White fibrous connective tissue: Collagen fibres are mostly found in this tissue. There is complete absence of yellow fibres and reticular fibres. Fibroblasts and mast cells are found more in number. It is present in the perichondrium, periosteum, muscles and nerves. It forms tendons which joins muscles to bones.
• Yellow fibrous connective tissue: Even though yellow elastic fibres are more in number, collagen fibres are also present. Reticular fibres are absent in this tissue. It is present in the vocal chords , elastic membranes of trachea and artery etc. It forms ligament which joints bone to bone

Specialised connective tissue:

• Reticular fibrous connective tissue: Also called as the lymphoid tissue.The matrix of this tissue is lymph. The cells are called as reticuloendothelial cells. It is present in the liver, splleen, lymph nodes etc. It provides strength and support.
• Mucoid connective tissue: It is also called as the embryoic tissue and it is mainly found during embryonic life. Matrix is abundant. It is present in the umbilical cord, vitreous body of eyeballs. It forms the umbilical cord.
• Pigmented connective tissue: This tissue is a modification of areolar connective tissue.It is present in the choroid, ciliary body,iris of the eye etc.

Skeltal connection tissue:

➣ It is also known as the supportin tissue.. It provides support to the body and plays a major role in locomotion. It is of two types - cartilage, bone

Cartilage:

• It is a flexible connective tissue.
• The matrix is called as chondrin and is made up of water, proteoglycans, proteins and lipids.
• The outer fibrous sheath is called as the perichodrium.
• It provides support and flexibility to the body.
• It prevents and wear and tear of bones due to friction.

Bone:

• It is called as called as osseous tissue.
• It is the hardest tissue in the body.
• It consists of five parts - periosteum matrix, bone cells, bone marrow and endosteum.
• The bone cells are also called as the osteocytes.
• The matrix is made up of a protein called as the ossein.

Vascular connective tissue:

➣ The fluid connective tissue is blood.

Blood:

• It consists of a fluid matrix along with free cells
• The blood plasm forms about 60% of the blood and is a yellow transparent colloidal mixture.
• The blood cells are RBCs or erythrocytes, WBCs or leukocytes, blood platelets or thrombocytes.
