extracellular space..

Back 27

takes up more room than the cell. no free surface

Front 28

connective tissue functions

Back 28

binding organs, support, protection , movement, storage,heat production, and transport

Front 29

fibrous connective tissue is

Back 29

most diverse, nearly all contain fibers and consist of ground substance

Front 30

components of fibrous connective tissue

Back 30

fibroblasts, macrophages, leukocytes, plasma cells, mast cells and adipocytes

Front 31

fibroblast produce

Back 31

fibers and ground tissue

Front 32

macrophages is

Back 32

large phagocytic cells. wander though connective tissue

Front 33

plasma cells does what?

Back 33

synthesizes disease fighting proteins called antibodies

Front 34

mast cells does what?

Back 34

inhibits blood clotting. secrets histamine.

Front 35

histamine does..

Back 35

increases blood flow by dilating blood vessels

Front 36

fibroblasts produces what types of fibers

Back 36

collagenous fibers, reticular fibers and elastic fibers

Front 37

collagenous fiber

Back 37

tough and flexible and resist stretching. 25% of the body's protein

Front 38

reticular fibers

Back 38

from a spongy like frame work for such organs and spleen and lymph nodes

Front 39

elastic fibers

Back 39

thinner than collagenous fiber. made up of protein called elastin.

Front 40

elastin ...

Back 40

coiled structure allows it to stretch and recoil like a rubber band

Front 41

type of fibrous connective tissue

Back 41

loose and dense

Front 42

loose connective tissue

Back 42

areolar and reticular

Front 43

dense connective tissue

Back 43

regular and irregular

Front 44

areolar

Back 44

abundant, binds epthelial to deeper tissue. mostly collagenous but also elastic and reticular. underlying epithelia, surrounding blood vessels, nervous between muscles and skin. binging and packing material. flexible and strong in any direction

Front 45

reticular

Back 45

supports lymphatic organs. spleen. lymph node and bone marrow. loose net work of reticular fibers and cells.
