Bones are living tissues that are made up of cells.

The skeleton is made up of bones. It provides support, protection and movement.

A tissue is a group of similar cells working together for the same function.

Red blood cells carry oxygen around the body.

Muscles

Movement

Biomechanics

Pupils will learn that particles of substances move within, into and out of cells by diffusion.

Pupils learned that in multicellular organisms, all the tissues and organs are made of cells.

This unit investigates the structure and functions of the human skeleton, including support, protection, movement, and blood cell production. Explore biomechanics, the interaction of muscles and the skeleton, and antagonistic muscles while measuring muscle force.

Human skeleton and muscles

The shortening of muscles, which requires energy.

Found in the heart and moves involuntarily.

Found in organs such as the stomach and intestines and moves involuntarily.

Joined to bones, and moves voluntarily to make bones move.

A ligament holds two or more bones together at a joint.

Cartilage is a strong, smooth tissue that is found inside a joint.

Antagonistic muscles work in pairs to move a bone at a joint.

Muscle contraction is the shortening of muscles.

A force is a push or a pull that acts on an object.

Biomechanics is the study of how the body moves.

A moment is the turning effect of a force.

The point around which an object can rotate is a pivot.
