Q

Dense Elastic Tissue

A

Stretches and recoils, strength in one direction (arterial walls, vertebral ligaments)

17
Q

Hyaline Cartilage

A

Solid but transparent matrix, supports structures and smooth joint surfaces (costal cartilages of ribs, nasal cavity)

18
Q

Fibrocartilage

A

Thick bundles of collagen, somewhat flexible and withstands great pressure (intervertebral disks)

19
Q

Elastic Cartilage

A

Abundant elastic fibers, rigid with flexibility (ears)

20
Q

Bone

A

Hard mineralized matrix, strength and support to organs

21
Q

Blood

A

Blood cells in plasma, transports nutrients and protection from infection (blood vessels)
