Question 10

Transitional Epithelium

Answer 10

Location: Urinary bladder, ureters, and part of urethra

Function: Stretches and relaces to accommodate change in volume

Question 11

Blood

Answer 11

Location: Within blood vessels
Function: Fas transport, immune response, clotting/transport of nutrients, wastes, and hormones

Question 12

Areolar Connective Tissue

Answer 12

Location: Subcutaneous layer, surrounding organs, papillary layer of dermis

Function: Surrounds and protects tissues and organs; loosely binds epithelium to deeper tissues; provides nerve and blood vessel packing

Question 13

Reticular Connective Tissue

Answer 13

Location: Forms stroma of lymph nodes, spleen, thymus, and bone marrow

Function: Provides supportive framework

Question 14

Adipose Connective Tissue

Answer 14

Location: Subcutaneous layer; covers and surrounds some organs

Function: Stores energy; protects, cushions, and insulates

Question 15

Dense Regular Connective Tissue

Answer 15

Location: Forms tendons/ligaments

Function: Resists stress applied in one direction

Question 16

Elastic CT

Answer 16

Location: Walls of arteries, trachea, bronchial tubes

Function: Allows stretching of some organs

Question 17

Dense Irregular CT

Answer 17

Compact Bone

Answer 18

Location: Exterior of bones

Function: Support

Question 19

Hyaline Cartilege

Answer 19

Location: Most of fetal skeleton, articular ends of bones, costal cartilage, nose

Function: Smooth surfaces for movement at joints, model for bone growth, supports soft tissue

Question 20

Fibrocartilage

Answer 20

Location: Intervertebral discs; pubic symphysis; menisci of knee joint
