A

fat cells

18
Q

blood

A

-liquid connective tissue -composed of plasma and cells -responsible for transporting substances such as nutrients and oxygen around the body

19
Q

bone

A

-a rigid organ -protect the various organs of the body, produce red and white blood cells, store minerals, provide structure and support for the body, and enable mobility

Q

chondrocyte

A

cells found in cartilage connective tissue

22
Q

connective tissue

A

-a primary tissue -functions include support, storage, and protection

23
Q

fibroblast

A

-a cell of connective tissue -secrete elastin and collagen protein fibers

24
Q

fibrosis

A

repair by dense (fibrous) connective tissue, that is, by the formation of scar tissue

25
Q

inflammation

A

-reaction to the invasion of microorganisms through the skin or through the epithelial layers of the respiratory, digestive, or urinary system -characterized by redness, swelling, heat, and pain

26
Q

lacunae

A

a little depression in bone or cartilage

27
Q

ligament

A

a cord of fibrous tissue that connects bones

28
Q

A

the watery fluid in the lymph vessels collected from the tissue spaces

29
Q

A

-cells that synthesize and release histamine (allergic reaction) -found most often in connective tissue surrounding blood vessels

31
Q

muscle tissue

A

-one of four main tissue types -specialized to contract in order to produce a force that will cause movement

32
Q

necrosis

A

-the death of body tissue -occurs when too little blood flows to the tissue
