Characteristics/Identification: a loose, flexible arrangement of fibers in a gel-like ground substance that makes it strong, yet flexible.

Structure-Function: contains fibroblasts, collagen, and elastic fibers that are embedded in a fluid ground substance, creating a flexible matrix that provides support, cushioning, and flexibility for surrounding organs. Used to bind epithelial tissue to deeper tissues, as a pathway for blood, houses immune cells like macrophages, and essential for nutrient exchange.

Characteristics/Identification: large, white, spherical cells within a sparse network of collagen and elastic fibers.

Structure-Function: large fat cells with minimized extracellular matrix, used for energy storage, thermal insulation, organ protection, and endocrine secretion of hormones.

Characteristics/Identification: a network of delicate, branched reticular fibers that form a supportive stroma within soft organs like lymph nodes.

Structure-Function: consists of stroma, the fine mesh-like internal framework, that is made up of collagen fibers, with specialized fibroblasts called reticular cells that are scattered throughout. The main function is to provide a supportive scaffold that houses and filters immune cells and blood cells, which is vital for immune response and organ functions.

Characteristics/Identification: has an abundance of collagen fibers that are arranged in a tight network, and a low cell and ground substance content. Fibers are aligned in a parallel shape, running the same direction with fibroblasts in the fibers.

Structure-Function: provides strong, flexible support that is important for structural support, protection and connecting tissues. the parallel fibers provide extra support in the tissue.

Characteristics/Identification: smooth, blueish-white, translucent cartilage that is firm but flexible consistency. Made of fine collagen fibers with the surrounding extracellular matrix.

Structure-Function: flexible yet tough due to the extracellular matrix and collagen fibers. They mainly provide structural support for organs like the nose, reduce friction, absorb shock joints, and serve as the template for bone development in long bones.

Characteristics/Identification: defined by a dense network of elastic fibers within its matrix that allows the cartilage to bend and return to its original shape without being damaged.

Structure-Function: flexible enough to stretch and move, but provides enough support for external organs such as the external ear. large amount of resilience from outside factors.

Characteristics/Identification: identified by a fibrous appearance with chondrocytes (cartilage cells) located in the lacunae (spaces between fibers).

Structure-Function: allows for easy shock absorption and provides support in areas like the intervertebral discs. shock absorption is important for safely landing on feet/knees.

Characteristics/Identification: has a fluid matrix called plasma that consists of red blood cells, white blood cells, and platelets. Red blood cells are shaped as discs while white blood cells are often various shaped and contain a nucleus.

Structure-Function: its primary function is to transport oxygen, nutrients, waste, and hormones, regulate homeostatic mechanisms such as temperature, pH, and fluid balance, and protect the body from infection and blood loss.

Characteristics/Identification: can be easily identified by its composition of organic and inorganic composition including collagen fibers and calcium phosphate.

Structure-Function: composed of dense compact bone and lightly spongy bone. it provides support, protection, and leverage for movement, while also providing a spot for mineral storage and blood cells production through bone marrow.
