1

Trachea

a large membranous tube reinforced by rings of cartilage, extending from the larynx to the bronchial tubes and conveying air to and from the lungs; the windpipe.

2

Rib cage

A protective layer of ribs surrounding the heart/lungs

3

Heart

An organ that pumps oxygenated blood around the body

4

Diaphragm

A dome shaped muscle that increases the volume of your chest therefore letting your lungs expand

5

Lung

It holds the oxygen

6

Bronchiole

any of the minute branches into which a bronchus divides.

7

Bronchus

any of the major air passages of the lungs which diverge from the windpipe.

8

Alveoli

any of the many tiny air sacs of the lungs which carry the air into the cells

9

Intercostal muscles

They help the rib-cage Move

10

Cell

The building blocks of everything

11

Tissue

What your organs and muscles are made of

12

Organ

Vital things (eg heart) made out of tissue

13

Organ system

A set of organs(eg skeletal system) working together to do one thing

14

Hierarchy of organisms

Organism
Organ system
Organ
Tissue
Cell

15

Tendon

What holds your muscles to your bone

16

Ligament

Holds your bones together in a joint

17

Bone

A part of your body that keeps you uprite

18

Joint

The thing that connects your bones

19

Muscle

These makes your bones move

20

Antagonistic pairs

A pair of muscles that work oppositely to move your bones. Eg biceps and triceps

21

Synovial fluid

A fluid that keeps your bones from wearing each other out

22

Cartilage

Cartilage stops your bones from rubbing therefore wearing each other out

23

Bone marrow

These are in side your bones and make red blood cells

24

Inhalation

When you breath in your chest expands and moves up then out

25

Exhalation

You breathe the carbon dioxide out and your chest goes back to normal

26

Allows 180 degrees movement

28

Hinge joint

You can move it back and forth

29

Immoveable joint

Doesn't move at all

Bone in your upper arm

32

Cranium

Skull

33

Mandible

Jaw

34

Clivicle

Shoulder blade

35

Sternum

Part in the middle of your rib cage

36

Rib cage

Bone that protect your heart and lungs

37

Radius

Bone on the under arm connected to the thumb

38

Ulna

Part of the under arm that connects to your wrist

39

Patella

Knee cap

40

Fibia

Part of the lower leg bone

41

Tibia
