2. Important and difficult points in learning:

Explain that the movement of animals depends on certain structures.

Animal movement forms and energy supply PPT, Part 2 content: Animal movement

All animals, including humans, can move in certain ways, which is an important feature that distinguishes animals from other creatures.

Movement is of great significance to animals. It allows animals to quickly change their positions to find food, escape enemies, and reproduce the species.

animal movement patterns

2. What role do joints play in movement?

1. Articular cartilage and synovial fluid in the joint cavity make the joint flexible, and the joint capsule and ligaments make the joint strong.

2.Joints serve as fulcrums.

Animal movement forms and energy supply PPT, Part 4: Movement system

The motion system also requires the cooperation of other systems

Nervous system: controls movement and provides instructions for movement.

Digestive system: Provides energy needed for muscle contraction.

Respiratory system: Provides oxygen needed for energy utilization and conversion.

Circulatory system: transports oxygen and nutrients, removes waste
