Types of epithelium tissues

Question 1

squamous epithelium - structure

Answer 1

single layer of flattened squamous cells

Question 2

squamous epithelium - function

Answer 2

thin, smooth flat layer - ideal for rapid diffusion

absorption + filtration

not effective protection (bc of single layer of cells)

Question 3

squamous epithelium - location

Answer 3

line alveoli in lungs

walls of capillaries

form membrane in body cavity

Question 4

ciliated columnar epithelium - structure

Answer 4

irregularly shaped cells with nuclei at different levels

reach basement membrane

Question 5

ciliated columnar epithelium - function

Answer 5

absorption + secretion

goblet cells produce mucus

cilia sweep mucus

protect from infection

Question 6

ciliated columnar epithelium - location

Answer 6

respiratory linings such as trachea

reproductive tract

Question 7

endothelium - structure

Answer 7

• a layer of flattened sacs

- one layer thick

Question 8

endothelium - function

Answer 8

provides short diffusion pathway + rapid movement of substances such as:

• products of digestion in capillaries
• blood plasma in and out of capillaries

Question 9

endothelium - location

Answer 9

found lining:

• heart
• blood vessels
• lymphatic vessels
