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.

Muscles

Science

The human skeleton

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

True or false? Skeletal muscle is joined to the bone.

Match the type of muscle to the organ system it is involved with.

What happens to a muscle cell when it contracts?

Laura: Gravity moves food through the digestive system.

Sam: Food is pushed through the digestive system by smooth muscle contracting.

Jun: Vibrations of the body when walking move food through the digestive system.

Jacob: Swallowing more food pushes the food through the digestive system.

True or false? All living things are made of cells.
