Loose areolar connective tissue
- Functions:
- Wraps and cushions organs, macrophages phagocytize bacteria, plays important role in inflammation, holds and conveys tissue fluid.
- Location:
- Widely distributed under epithelia of body, packages organs, surrounds capillaries.
-
Adipose connective tissue
- Function:
- Provides reserve food fuel, insulates against heat loss, supports and protects organs.
- Location:
- Under skin, around kidneys and eyeballs, within abdomen, in breasts.
-
Reticular connective tissue
- Function:
- Fibers form a soft internal skeleton (stroma) that supports other cell types.
- Location:
- Lymphoid organs (lymph nodes, bone marrow, and spleen).
-
Dense connective tissue
- Function:
- Able to withstand tension exerted in many directions, provides structural strength.
- Location:
- Dermis of the skin, submucosa of digestive tract, fibrous capsules of organs and of joints.
-
Dense regular connective tissue
- Function:
- Attaches muscles to bones or to muscles, attaches bones to bones, withstands great tensile stress when pulling force is applied in one direction.
- Location:
- Tendons, most ligaments, aponeuroses.
-
Connective tissue: Hyaline cartilage
- Function:
- Supports and reinforces, has resilient cushioning properties, resists compressive stress.
- Location:
- Forms most of the embryonic skeleton, covers the ends of long bones in joint cavities, forms costal cartilages of the ribs, cartilages of the nose, trachea, and larynx.
-
Connective tissue: Elastic cartilage
- Function:
- Maintains the shape of a structure while allowing great flexibility.
- Location:
- Supports the external ear (pinna), epiglottis.
-
Connective tissue: Fibrocartilage
- Function:
- Tensile strength with the ability to absorb compressive shock.
- Location:
- Inervertebral discs, pubic symphysis, discs of knee joint.
-
Connective tissue: Bone
- Function:
- Supports and protects, provides levers for the muscles to act on, stores calcium and other minerals and fat, marrow inside bones is the site for blood cell formation.
-
Connective tissue: Blood
- Function:
- Transport of respiratory gases, nutrients, wastes, and other substances.
- Location:
- Contained within blood vessels.
