Exploring Levels of Organization in the Human Body

1. 1.2 Levels of Organization 2.1 Atoms, Ions, and Molecules • Sponge: Set up Cornell Notes on pg. 7 • Topic: 1.2 Levels of Organization Essential Question: Explain how organs and organ systems are related. Text: P. 4-6 • Explain how organs and organ systems are related. Vocabulary: Subatomic particles Atoms Molecule Macromolecule Organelle • Cell • Tissue • Organ • Organ system • Organism • Get out your HW • Get a Chromebook

3. Objective Students will understand the levels of organization in the human body from cell to organism • The students will create a picture flow map showing the levels of organization of a human body system of their choice

4. Levels of Organization Simple    Most Complex

5. Levels ofOrganization What is the smallest building block that you can think of? Can we get any smaller?

6. Levels ofOrganization Subatomic Particles – electrons, protons, neutrons Atom – Basic unit of matter Ex: Hydrogen/ oxygen Molecule- Atoms bound together Ex: Water molecule Macromolecule- Molecules bound together Ex: proteins/carbohydrates/ lipids/nucleic acids

7. Levels ofOrganization Think back to Biology, what is the smallest building block of LIFEthat you can think of? Can we get any smaller?

8. Can you name any organelles? Exs: • Mitochondria- powerhouse of cell • Nucleus- contains genetic info (DNA) Organelles: Carry out specific activities in the cell

9. Can you name any cells? Exs: • Red blood cell- delivers oxygen to all tissues • Neurons: provides a pathway for electrochemical nerve impulses Cells: Basic unit of life. Organisms are made up of specialized cells that each have a particular structure that enables it to perform a specific function

10. cell tissue Levels ofOrganization If I put a bunch of similar cells together what can I build?

11. cell tissue Tissues:are groups of similar cells working together to perform a specialized function Exs: • Epithelial tissue • Connective tissue • Muscle tissue • Nervous tissue

12. Levels ofOrganization If I put different tissues together, what can I build?

13. Can you name some organs? Exs: • Stomach • Liver • Lungs Organs:are different types of tissues working together to perform a function

14. Levels ofOrganization If I put differentorgans together, what can I build?

15. Organ systems: two or more organs working together to perform a function • Perform the most complex activities in the body Exs: • Respiratory system • Circulatory system • Digestive system

16. There are 11 major organ systems in the human body (p. 8in Anatomybook)

17. Organism:The organ systems make up the entire organism. • For the organism to stay alive, all of the systems must interact and work together.

20. Levels of Organization Flow Map Create a picture flow map showing the levels of organization of a human body system of your choice *Can choose any organ system EXCEPT the respiratory system

21. Levels of Organization Flow Map (p. 6) Sources: Cells/Organelles p. 77-91 Systems/Organs p. 8 *Internet Organ System Organ Tissues Cells Organism • Human • picture • Chose ONE organ from your organ system list • Describe its function • picture • Name ONE type of tissue that makes up your organ • picture • Name ONE type of cell that makes up your tissue • picture • Choose an organ system • Describe the function of it • List the organs involved • picture Easier to plan backwards

22. Levels of Organization Flow Map (p. 6) Cells/Organelles p. 77-91 Systems/Organs p. 887-1011 *Internet Ex: Respiratory System Ex: lung cell Ex: Human Ex: lung tissue Ex: lung Organ System Cells Organism Tissues Organ • Human • Picture • Type of Tissue • Picture • Type of Cell • Picture • Organ name • Function of organ • Picture • Organ system name • Function of organ system • List of organs involved • Picture Muscle/epithelial/ connective/nervous Picture *Easier to work backwards *CANNOT DO RESPIRATORY SYSTEM

24. Levels of Organization Flow Map Example Organ System Organ Tissue Cells Organism • Lungs • Function: Site where gases are exchanged • Human • Lung cell (epithelial lung cell) • Lung Tissue (epithelial tissue) • Respiratory System • Function: Brings O2to cells and expels CO2 and water vapor • Parts: Lungs, Nose, sinuses, pharynx, larynx, trachea Easier to plan backwards
