Lesson Details
Key learning points
- Humans are multicellular organisms; the human body is made up of millions of living cells.
- Every cell must be supplied with substances for respiration, growth and repair; waste products must be removed.
- The circulatory system transports substances between cells and the gas exchange, digestive and excretory systems.
- The circulatory system is made up of the heart, blood vessels and blood.
Common misconception
Nutrients and waste are either not produced, or not by every cell, with misconceptions about where these substances come from or go to and what the roles of the various systems are as a result.
Key nutrients and waste products are dealt with individually and related to the relevant body systems. These ideas are focused on in main and check tasks.
