• 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 1. 2 Ions, Levels 2. 1 Atoms, and Molecules of Organization Explain how organs and organ systems are related. Vocabulary: Subatomic particles Atoms Molecule Macromolecule Organelle Cell Tissue Organ system Organism
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
Levels of Organization 3
Levels of Organization Subatomic Particles – electrons, protons, neutrons Atom – Basic unit of matter Molecule – Atoms bound together Macromolecule – Molecules bound together 4
Organelles: Carry out specific activities in the cell Exs: • Mitochondria- powerhouse of cell • Nucleus- contains genetic info (DNA)
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 task Exs: • Red blood cell- delivers oxygen to all tissues • Nerve cell- provides a pathway for electrochemical nerve impulses
Tissues: are groups of similar cells working together to perform a specialized function Exs: • Epithelial tissue • Muscle tissue cell tissue
Organs: are different types of tissues working together to perform a function Exs: • Stomach • Liver • Lungs
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
There are 11 major organ systems in the human body (p. 856 in bio book)
Organism: The organ systems make up the entire organism. • For the organism to stay alive, all of the systems must interact and work together.

Levels of Organization Flow Map Create a picture flow map showing the levels of organization of a human body system of your choice
Levels of Organization Flow Map (p. 6) Sources: Cells/Organelles p. 77 -91 Cells • Name ONE type of cell that makes up your tissue Tissues Systems/Organs p. 887 -1011 Organ System *Internet Organism • Human • Chose ONE • Name organ from • Choose an ONE type organ system your organ of tissue – Describe the system list that makes function of it – Describe up your – List the its organs function involved *Use organ system handout Easier to start backwards
Levels of Organization Flow Map Example Cells • Lung cell (epithelial lung cell) Tissue • Lung Tissue (epithelial tissue) Organ System Organism • Lungs • Human • Function: Site • Respiratory where gases System are exchanged • Function: Brings O² to cells and expels CO² and water vapor • Parts: Nose, sinuses, pharynx, larynx, trachea, lungs
Levels of Organization Flow Map (p. 6) Cells/Organelles p. 77 -91 Systems/Organs p. 887 -1011 Ex: lung cell Ex: lung tissue Cells Ex: lung Tissues Organ • Type of Cell • Picture • Type of Tissue • Picture e r u t c Pi *Internet Ex: Respiratory System Organ System Ex: Human Organism • Organ name • Organ system • Human • Picture – Function name of organ – Function of • Picture organ system – List of organs involved • Picture Muscle/epithelial/ connective/nervous *CANNOT DO RESPIRATORY SYSTEM
