• 1) To provide us shape
• 2) So we can move
• 3) so we can stand up straight without falling

yes

• 1.arteries carry the blood away from the hear whereas veins bring the blood towards the heart.
• 2.arteries have more thickness  whereas veins have thin walls.
• 3.Arteries take oxygenated blood away from the heart and veins take de-oxygenated blood back to the heart.

Mouth/nose --> Trachea --> Bronchi --> bronchioles --> Alveoli --> blood stream

A blood vessel that moves blood, usually deoxygenated from the body back to the heart.

A blood vessel that moves blood (usually oxygenated from the heart to another part of the body)

Very small blood vessels that connect arteries to veins.

The hard internal structures (bone and cartilages) that provide a jointed frame for the body/

A muscle that opposes the action of another. The biceps and triceps are antagonistic muscles.

The process where some organisms obtain energy from food, usually required oxygen and producing carbon dioxide.

To reduce friction and acts as a shock absorber

Keeps cartilage lubricated and holds it in place

Produces synovial fluid

Join the two bones and stop them from coming apart.

• -responsible for fighting infection and disease.
• - The number of white blood cells increase when a person if fighting an infection or disease
• - Approximately 1% of our blood is made up of white blood cells and platelets.

• - Contain a chemical cooled haemoglobin that carries oxygen around your body.
• - make up 45% of your blood.

• - plasma makes up about 54% of our blood
• - Straw coloured
• - transports carbon dioxide from our cells to our lungs and nutrients from the small intestine to our cells.
• - also transports chemical messengers called hormones to your cells.
