Protect organs

Support

Makes red blood cells

Used to create movement with

muscles

When a muscle contracts (shortens) it pulls on the tendon which pulls on the bone to cause movement.

Muscles work in pairs because they can only pull, not push (one pulls arm up, other pulls arm down)

Pairs of muscles work in the opposite direction –antagonistic pairs

Tendons connect muscle to bone

Ligaments link bones

Many animals have skeletal systems that are very similar to ours.

Our leg is very much like that of a chicken leg including:

• femur (thigh bone)• knee (hinge joint)• fibula and tibia (smaller bones of the shin)• cartilage• ligaments

These are all part of our skeletal system. Beyond that, we also have similar muscle structure, tendons, fat, and skin. We will be exploring each of these similar characteristics.

A). Fibers that contract and relax to effect body movement

B). An elastic tube through which blood circulates.

C). A tough, semi-rigid, calcified part of the skeleton

D). connects two bones together.

E). protective covering

F). It covers the surface of joints, allowing bones to slide over

one another, thus reducing friction and preventing damage.

Keeps bones from touching one another.

G). connects muscle to bone

H). A point of connection between two movable parts

Blood carries food, oxygen and

hormones to the cells around your

body, it removes wastes, carbon

dioxide and extra heat from the

cells.

Blood is made up of:

• Plasma – saline solution, blood

is mostly this

• Red blood cells – transport CO2

& O2

• Blood platelets – clotting agent

• White blood cells – fight

infection

Gases move from high to low concentration

CO2 moves out of cells and into blood

O2 moves out of blood and into cells

Ribs, diaphragm and lungs move to change

pressure to cause air to move in and out of

lungs

carbon dioxide

Converting oxygen and glucose into energy to

be used by muscles

Produces carbon dioxide and water as a

waste
