What are the 6 types of connective tissues?
Fibrous, Loose, Adipose, Bone, Cartilage, and Blood
Describe loose ct?
The matrix has a loose weave of fibers (collagen and elastin). Mainly binding and packing and found under the skin.
Describe fibrous ct.
The matrix is densely packed parallel bundles of fibers, and maximizes strength, and forms tendons and ligaments.
Describe Adipose ct
it stores fat in closely packed cells with sparse matrix of fibers, it insulates the body and stores fat
Describe cartilage ct
the matrix consists of tons of collagen fibers embedded in a rubbery substance. It forms a strong but flexible skeletal material. It surrounds the ends of bones to create a shock absorbing surface. Supports the nose and ears and form cushioning discs between the vertebrae
Describe bone ct
it is a rigid ct and the matrix of collagen fibers embed in calcium salts which makes them hard but not brittle
Describe blood ct
the matrix is a liquid called plasma which consists of water, salts and dissolved proteins. Red and white blood cells are suspended in the plasma. It functions in transporting substances and in immunity
