Areolar Tissue vs. Adipose Tissue: What's the Difference?

Edited by Aimie Carlson || By Harlon Moss || Updated on October 29, 2023
Areolar tissue is a loose connective tissue providing support and flexibility, while adipose tissue stores fat and insulates the body.

Key Differences

Areolar tissue is a type of connective tissue characterized by its loose and flexible structure. Adipose tissue is specialized in storing fat and providing insulation and cushioning.
In areolar tissue, collagen and elastin fibers are loosely arranged, providing elasticity and support. Adipose tissue is composed of tightly packed fat cells (adipocytes) that store energy.
Areolar tissue is found around organs, supporting and protecting them. Adipose tissue is located under the skin and around internal organs, helping to regulate temperature.
Areolar tissue plays a role in the immune response by housing various immune cells. Adipose tissue, besides energy storage, secretes hormones and cytokines.
Areolar tissue helps in the diffusion of nutrients and waste between cells and the bloodstream. Adipose tissue is a major energy reserve in the body, releasing fatty acids when needed.

Areolar Tissue and Adipose Tissue Definitions

Areolar Tissue

Involved in immune response.
The areolar tissue houses immune cells that fight infection.

Adipose Tissue

Secretes hormones and cytokines.
Adipose tissue contributes to hormonal balance by secreting leptin.

Areolar Tissue

Fills spaces between organs and connects skin to underlying tissues.
Areolar tissue connects the skin to muscles beneath.

Adipose Tissue

Releases fatty acids for energy.
During fasting, adipose tissue releases fatty acids for fuel.

Areolar Tissue

Loose connective tissue providing elasticity and support.
The areolar tissue under the skin allows for flexible movement.

Adipose Tissue

Tissue specialized in storing fat.
Adipose tissue in the body stores excess calories as fat.

Areolar Tissue

Contains fibers and a variety of cells for support and defense.
The areolar tissue's fibers give strength to the surrounding area.

Adipose Tissue

Composed of densely packed adipocytes.
The adipocytes in adipose tissue store energy for later use.

Areolar Tissue

A site for nutrient and waste exchange.
Nutrients diffuse through the areolar tissue to reach cells.

Adipose Tissue

Provides insulation and protection to the body.
The adipose tissue under the skin helps retain body heat.


How do areolar and adipose tissue differ in function?
