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.

Carries away wastes such as carbon dioxide that body cells produce.

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

There are three types of vessels in the human body, and each have a special structure and function
Arteries take blood away from the heart, they are thick walled to withstand the pressure of the pumping blood
Veins take blood back to the heart and have valves to prevent the blood flowing backwards
Capillaries are thin walled so that gases can diffuse through to cells
