Q

Epithelial tissue has its own nerve supply, but is avascular/vascular, relying on the blood vessels of the adjacent connective tissue to bring nutrients and remove wastes.

Q

What type of epithelial tissue is keratinized when surface cells become dead and hardened?

A

Stratified squamous epithelium

16
Q

Which type of epithelial tissue allows diffusion of gases and nutrients?

A

Simple squamous

17
Q

Which type of epithelial tissue lines the urinary bladder and parts of the ureters and urethra where it permits dissension of the organs?

A

Transitional

18
Q

Endocrine/exocrine glands secrete hormones that enter the interstitial fluid and then diffuse directly into the bloodstream without flowing through a duct.

A

Endocrine

19
Q

Endocrine/exocrine glands secrete their products into ducts that empty onto the surface of a covering and lining epithelium such as the skin surface.

A

Exocrine.

20
Q

Connected tissue consists of two basic elements.

What are they?

A

Cells and extracellular matrix.

21
Q

Unlike epithelial tissue which is vascular/avascular, connective tissue usually is vascular/avascular; that is, it has a rich blood supply.

A

Avascular, vascular.

22
Q

The extracellular matrix of connective tissue consists of two major components. What are they?

A

The ground substance and fibers.

23
Q

Which type of fibers form the stroma of many soft organs?

A

Reticular fibers.

24
Q

Ability to regenerate tissue depends on three things.

What are they?

A

Nutrition, circulation, and age.

25
Q

Vitamin C/ vitamin D is needed for normal production and maintenance of connective tissue.

A

Vitamin C.

26
Q

Cartilage is one type of mature connected tissue. Because cartilage is a vascular, it is relatively inactive tissue that grows slowly and regenerates proceeds quickly/slowly.

A

Cartilage regenerates slowly.

27
Q

Epithelial regenerate easily and well. True or false?

A

True.
