Cells, Tissues & Organs
细胞、组织与器官
Description
Understand that the body is organised in a hierarchy: tiny cells are the building blocks, groups of similar cells form tissues, tissues combine into organs (like the heart or stomach), and organs work together in organ systems (like the circulatory system)
Mastery Evidence
- State that cells are the smallest building blocks of the body, too small to see without a microscope
- Describe the hierarchy: cells → tissues → organs → organ systems
- Give an example: muscle cells form muscle tissue, which forms the heart organ, which is part of the circulatory system
Assessment Prompt
Can your child explain that the body is made of tiny cells, and that cells group together to make tissues, which make organs, which make whole systems?
