Biomaterials Introduction

Question 1

What is tissue?

Answer 1

Collection of cells and extra-cellular matrices that together carry out a specific function

Question 2

Function of connective tissue and three types of connective tissue

Answer 2

Function: holds organs in place, gives the body shape, is involved in doing mechanical work
Areolar: holds organs in place and has variety of fibres
Adipose: holds fat deposits
Fibrous: makes ligaments and tendons, densely packed collagen fibres so strong

Question 3

Function of epithelial tissue

Answer 3

Lining tissue for inner and outer surfaces; protects but also allows for passage of chemicals as necessary

Question 4

Function and two types of muscular tissue

Answer 4

Function: use body fuel to generate forces by contraction - do mechanical work
Skeletal muscle - voluntary muscle: links tendons to bones and moves your arms and legs around
Smooth muscle and cardiac muscle - involuntary actions / not under conscious control

Question 5

Four basic engineering tasks organs do

Answer 5

• Work in tension
• Work in compression
• Provide a permeable partition
• Allow for fluid transport

Question 6

Solutions to tissue disfunction/loss

Answer 6

• amputation
• prosthetic
• implant (eg pacemaker)
• transplant
