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 from last night for signature
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 ofOrganization Subatomic Particles – electrons, protons, neutrons Atom – Basic unit of matter Molecule – Atoms bound together Macromolecule – Molecules bound together
Exs: • Mitochondria- powerhouse of cell • Nucleus- contains genetic info (DNA) Organelles: Carry out specific activities in the cell
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
cell tissue Tissues: are groups of similar cells working together to perform a specialized function Exs: • Epithelial tissue • Muscle tissue
Exs: • Stomach • Liver • Lungs Organs: are different types of tissues working together to perform a function
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 *Can choose any organ system EXCEPT the respiratory system
Levels of Organization Flow Map (p. 6) Sources: Cells/Organelles p. 77-91 Systems/Organs p. 887-1011 *Internet Organ System Organ Tissues Cells Organism • Human • pic • Chose ONE organ from your organ system list • Describe its function • pic • Name ONE type of tissue that makes up your organ • pic • Name ONE type of cell that makes up your tissue • pic • Choose an organ system • Describe the function of it • List the organs involved • pic Easier to start backwards
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
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 O² to cells and expels CO² and water vapor • Parts: Nose, sinuses, pharynx, larynx, trachea, lungs
