Lines body cavities; blood vessels; ducts; and the interiors of the respiratory, digestive, urinary, and reproductive systems

Answer 2

Epithelial Tissue

Question 3

This cells are thin, and allows for the rapid passage of substance through them

Answer 3

Squamous cells

Answer 7

1. Simple Squamous- flat cells
2. Simple cuboidal - cube-shaped
3. Simple Columnar - rectangular shaped
4. Simple ciliated - with fine hair-like processes — CILIA

2 types of stratified epithelium

Answer 8

1. Keratinized: dry surface; skin, hair, nails
2. Non-keratinized: wet surfaces; lining of mouth, pharynx, esophagus, vagina

Question 9

This type of epithelium tissue stretches as urine passes

Answer 9

Transitional epithelium

Question 10

A _________ may consist of one cell or a group of highly specialized epithelial cells that secrete substances into ducts, onto a surface, or into the blood

Answer 10

Gland

Question 11

This type of glands enter the interstitial fluid and then diffuse into bloodstream without flowing through a duct. These secretions are called hormones

Answer 11

Endocrine glands

Question 12

This type of glands secrete their products into ducts that empty at the surface jf covering and kining epithelium such as the skin surface or the lumen of a hollow organ

Answer 12

Answer 20

Plasma cells

Question 21

______ in the extracellular matrix strengthen and support connective tissue

Answer 21

Fibers

Question 22

These fibers are very strong and resist pulling forces, but they are not stiff, which promotes tissue flexibility

Answer 22

Collagen fibers

Question 23

These fibers are smaller in diameter than collagen fibers, branch and join together to form a network within a tissue

Answer 23

Elastic fibers
