Document Summary
Different ratio of each part will dictate the different function of tissue: protein fibers strong, flexible, inelastic, collagen. Made 25% of all protein in the body give strength of protein cannot be stretch and bring back to its shape. Molecules are cross-linked can be stretched and them bring back to the original shape. Can attach proteoglycan to the side of the cell. Attach cell to each other: fluid. Blood has more fluid portion (contain ions, nutrients etc) Bone does not have much fluid but more protein fibers. Regular: protein fiber oriented in the same direction. Irregular: protein fiber oriented in the different direction (90 degree) Loose packing material of most organs and tissues ( fills the gaps) Fat can be a part of areolar tissue. Contains collagen, reticular, elastic fibers (all 3, but most of them are collagen) Dense regular collagenous ct (don"t have good blood supply) Has abundant collagen fibers that resist stretching.
