• 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 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 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 *Can choose any organ system EXCEPT the respiratory system

Levels of Organization Flow Map (p. 6) Sources: Cells/Organelles p. 77 -91 Cells • Name ONE type of cell that makes up your tissue • pic Tissues Systems/Organs p. 887 -1011 Organ System *Internet Organism • Human • Chose ONE • Name • pic 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 • pic involved – pic Easier to start backwards

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 *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 *Easier to work backwards Pi *CANNOT DO RESPIRATORY SYSTEM

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
