Functions of Loose Connective Tissue:

• Support: It provides support and strength to the organs and structures it surrounds.
• Elasticity: It allows for flexibility and stretching of the tissues.
• Diffusion: It facilitates the diffusion of nutrients, gases, and waste products between blood vessels and surrounding tissues.
• Immune response: It houses immune cells that help in the body's defense against pathogens.

The matrix of loose connective tissue is composed of collagen and elastic fibers, which are embedded in a gel-like ground substance. This ground substance contains water, glycoproteins, and glycosaminoglycans, providing a medium for nutrient exchange and support. The cells present in this tissue, such as fibroblasts, macrophages, and adipocytes, are scattered throughout the matrix.

1. Areteolar Tissue: Found beneath the skin, around blood vessels, and nerves. It provides support and elasticity.
2. Adipose Tissue: Specialized for fat storage and insulation. It also cushions and supports organs.
3. Reticular Tissue: Forms the stroma of organs, providing structural support and anchoring cells.
