Question 1

3 important functions of connective tissue
Specific example from the body
Location of each tissue sample

Answer 1

Bonds body tissue together- dense regular: tendons connect muscle to bone.
Supports body- elastic: maintain ear structure
Protection- bone: hard and calcified protects organs

Question 2

3 important functions of epithelial tissue
Specific example from the body

Answer 2

Covers all body surfaces: stratified squamous: skin
Major tissue of glands: simple cuboidal: secretion and absorption- gland ducts
Reproduce rapidly: psuedostratified columnar: trap and move foreign objects- trachea
