Q

Do bones grow?

A

Yes they grow in length from ages 15-18 for girls and 16-18 for boys

18
Q

What are joints?

A

They occur when two or more bones meet and join together

19
Q

What are the three types of joints?

A

Immovable fibrous joints
Slightly movable cartilaginous joints
Freely movable joints synovial

20
Q

What are connective tissue?

A

They create movement at the joint and act as a lubricant and shock absorber between the bones

21
Q

What are the three main types of connective tissue?

A

Cartilage
Tendons
Ligaments

22
Q

How many muscles do we have?

A

Over 600

23
Q

Can people be born with more or less of slow/fast twitch fibres? What would they be better at?

A

Yes if more fast fibres then you are naturally better at fast paced things if more slow you are naturally better at long duration and low effort

24
Q

How many fast/slow twitch fibres do we have?

A

We usually have an even amount but can increase the fast or slow fibres by specifically training them

25
Q

What does the nervous system do?

A

Sends messages to the rest of the body

26
Q

What does the endocrine do?

A

It makes hormones

27
Q

What does our skin do?

A

Protects us from disease and keeps fluids inside our bodies

28
Q

What does the respiratory system do?

A

Oxygen intake and carbon dioxide removal

29
Q

What does our circulatory system do?

A

Transports materials to and from all body cells

30
Q

What does excretory system do?

A

Excretion of waste products

31
Q

What does our digestive system do?

A

Provides nutrients for energy production

32
Q

What does our skeletal system do?

A

Provides movement, shape and protection of vital organs

33
Q

What does our muscular system do?

A

Creates movement by pulling on our bones, aids digestion and breathing

34
Q

What does the reproduction system do?

A

Reproduces our species

35
Q

What does our physical, mental and emotional health depend on?

A

Depend on all the systems of the body being in order

36
Q

What do bones do?

A

Provide framework and levers for movement

37
Q

What do muscles do?

A

Muscles pull on our bones (levers) to create movement

38
Q

What do joints do?

A

They allow us to bend thus creating movement

39
Q

What is bone made up of?

A

50% water 50% solid

40
Q

Do bones have a hollow centre?

A

Yes some long bones are hollow which has bone marrow inside

41
Q

Are bone living?
