Fibres present in connective tissue are:

Connective tissue is a type of tissue found throughout the body that provides support and connects different structures together. It is composed of cells and extracellular matrix, which includes various types of fibres. The fibres present in connective tissue are:

1. Reticular Fibres:
- Reticular fibres are thin and delicate fibres that form a network or mesh-like structure.
- They are composed of type III collagen and glycoproteins.
- Reticular fibres provide support to various organs and tissues, such as the liver, spleen, lymph nodes, and bone marrow.
- These fibres form the framework of these organs and help in maintaining their shape and structure.

2. Elastin Fibres:
- Elastin fibres are stretchable and elastic in nature.
- They are composed of the protein elastin, which is responsible for their unique properties.
- Elastin fibres allow tissues and organs to stretch and recoil without damage.
- They are found in tissues that require elasticity, such as the skin, blood vessels, lungs, and ligaments.

3. Collagen Fibres:
- Collagen fibres are the most abundant fibres in connective tissue.
- They are composed of the protein collagen, which provides strength and support to tissues.
- Collagen fibres are strong, flexible, and resistant to stretching.
- They are found in various structures, including tendons, ligaments, bones, cartilage, skin, and blood vessels.

Conclusion:
In conclusion, the fibres present in connective tissue are reticular fibres, elastin fibres, and collagen fibres. These fibres play important roles in providing support, elasticity, and strength to different organs and tissues in the body.
