One major function of connective tissue proper is to physically support and connect other tissues. A second major function is to

Answer 8

Answer 13

Fibroblasts

Question 14

The formation of scar tissue following surgery or wounding is largely due to

Answer 14

Fibroblasts

Question 15

The two major types of protein fibers in the ECM are

Answer 15

Collagen and elastic

Question 16

What is interstitial fluid?

Answer 16

It is water in the ground substance of connective tissue.

Question 17

Reticular fibers are made of type III collagen. They function as a supportive stroma in which organs/glands?

Answer 17

Endocrine glands, Lymphoid organs, Hematopoietic organ

Question 18

The largest and most unique GAG (glycoaminoglycan) is:

Answer 18

Hyaluronic acid (hyaluronan)

Question 19

In the presence of an allergen (which can from any of a number of things such as insect venom, peanuts, penicillin, etc.), release of certain chemicals from mast cells may promote an allergic reaction known as an immediate hypersensitivity (also called Type I hypersensitivity) reaction. How is this reaction different from the normal infectious immune response of mast cells?

Answer 19

The immediate hypersensitivity reaction typically requires a previous sensitization to the allergen.

Answer 20

Macrophage
