Grade 5 - Levels of Organization

1. Levels of Organization

2. Name the levels of organization in the correct order. Describe and write a definition for each level. Give linked examples for each level. Learning Points

3. What does the ‘levels of organization’ mean? The body is made of many systems Each body system is made of parts that work together to do a job. The body is highly organized and follows a hierarchy, from the simple cell to the complexity of a whole organism.

4. Cell Cells are the smallest independent living part of the human body .  e.g. Body is made up of billions of billions of cells Cells have special job to do e.g. muscle cells contract to move something, and red blood cells carry oxygen ) Cell structure - National 5 (youtube.com)

6. Tissue Bing Videos A tissue is a group of similar cells that work together to perform a specific function. There are four main tissue types in humans (muscular, epithelial, nervous and connective) .

8. Organ An organ is a structure of the body composed of two or more tissues types (for example, the stomach contains muscular tissue made of muscle cells, which allows it to change its shape, epithelial tissue which lines both the inner and outer surface of the stomach, nervous tissue which sends and receives signals to and from the stomach . .

9. Organ System An organ system is a group of organs that work together to perform a specific function (for example, the stomach, small and large intestines are all organs of the digestive system, that work together to digest foodstuff, move nutrients into the blood and get rid of waste) .
