Human Body Systems Interactive Simulation

The human body is a collection of organ systems that work together. The circulatory system pumps blood; the respiratory system exchanges gases; the digestive system extracts energy from food; the skeletal system provides structure; and the nervous system coordinates everything. No system works in isolation — they constantly communicate and depend on each other. Students can change body system and compare what happens. Use it for biology inquiry with Grades 3–5 and Middle School on a projector or student device.

Standards: NGSS MS-LS1-3, 4-LS1-1

• Why the heart must beat continuously to keep the circulatory system running
• How the respiratory and circulatory systems work together to deliver oxygen to every cell
• What happens in each stage of digestion as food moves through the body
• How bones protect soft organs and enable movement by working with muscles
• How the brain sends electrical signals through nerves to control muscles and senses

1. 1Predict how changing body system will affect the visible outcome, then test the prediction.
2. 2Use evidence from the interactive visual to explain the result.
