PHGY 170- Module 1 Exam Questions And
Answers 100% Pass
Epithelial Cells - ANSWER - form protective barriers in tissues
- may be specialized to absorb or secrete certain compounds
Muscle Cells - ANSWER - responsible for the movement of the skeleton, heart, and internal
organs
Nerve Cells - ANSWER - conducts electrical signals in the body
- controls contraction of muscles
- responsible for the 5 senses
Connective Tissue Cells - ANSWER - creates extracellular material that holds cell together
- specialized to absorb or resist external forces
Bone Cells - ANSWER forms bones (tough)
Secretory Cells - ANSWER - forms glands

- high heat of vaporisation
How Water Supports Cells - ANSWER - polar properties = excellent solvent that facilitates
delivery of nutrients and removal of wastes
