lagringsvävnader

Lagringsvävnader, also known as connective tissue, is a broad category of tissues in the body that provide support and structure. They are composed of cells called fibroblasts, which produce the extracellular matrix, a complex network of proteins and glycoproteins. The primary functions of lagringsvävnader include:

Support: They provide structural support to organs and tissues, such as the skin, bones, and internal organs. The extracellular matrix, particularly collagen and elastin fibers, gives strength and flexibility to these structures.

Separation: Lagringsvävnader act as barriers, separating different organs and tissues. For example, the peritoneum lines the abdominal cavity and the pleura surrounds the lungs.

Transport: They facilitate the movement of cells and molecules within the body. For instance, the lymphatic system, a type of lagringsvävnader, transports lymph fluid and immune cells.

Storage: Lagringsvävnader store fat, water, and other substances. Adipose tissue, a type of lagringsvävnader, is specialized for fat storage.

Immune response: They play a role in the immune system by producing cytokines and other immune factors.

Lagringsvävnader can be further classified into several types, including:

Loose connective tissue: Found in areas where flexibility is important, such as the dermis of the skin.

Dense connective tissue: Provides strength and support, found in areas like tendons and ligaments.

Elastic connective tissue: Allows for stretching and recoiling, found in areas like the lungs and blood vessels.

Cartilaginous connective tissue: Provides flexibility and shock absorption, found in areas like the nose and external ears.

Bone: The hardest and most rigid form of connective tissue, providing structural support and protection.
