Question 13

Adipose

Answer 13

-loose tissue
-filled with fat (triglycerides)

Question 14

Reticular

Answer 14

-loose tissue
-made up of reticular fibers (made of collagen)
-provides framework to hold organs together in place
-liver and spleen

-lacuna (space surrounding a cell)
-fetal skeleton, in joints at end of long bones, soft part of the nose

Question 16

Fibrocartillage

Answer 16

-dense tissue
-made up of collagen fibers
-provides a long framework for organ its in
-example: vertebral disc acts as a cushion

Question 17

Blood

Answer 17

-dense tissue
-liquid connective tissue
-transports oxygen and nutrients throughout the body VIA hemoglobin
-consisting of white blood , red blood cells, plasma, platelets, cryoprecipiate (factor 8)
