Body Organization

1. Body Organization • a. cell, b. tissue, c. organ, d. organ system • Cell • d. cell membrane • Nucleus • Every thing in a cell between the cell membrane and the nucleus • True • A tissue is a group of cells working together for the same purpose

2. Muscle – makes parts of the body move Nervous – controls body functions Connective – connects parts and support • Epithelial – surrounds organs and protects them • Organ • c. lungs • True • A group of organs working together for a purpose • d 15. c 17. e • f 16. a 18. b

3. Levels of Organization in Living Things

4. All living things are organized into several basic levels of organization. • Starting with the smallest and going to the largest it goes… • Cell -> Tissue->Organ->Organ system -> Organism

5. Cell • The basic level of Organization for all living things is the cell. • Complex organisms are composed of many cells Examples: • Heart Cell • Brain Cell • Muscle Cell

6. Tissue • Within an organism groups of cells with similar functions combine to make up tissues. • A tissue is a collection of cells working together to perform a specific job • FOUR BASIC TISSUES • Connective Tissue • Nervous Tissue • Muscle Tissue • Epithelial Tissue

7. Organ • Two or more types of tissues that work together to complete a specific task Examples: • Heart • Brain • Muscle • Skin

8. Organ Systems • Group of organsworking together for a common goal combine to make up organ systems Example: • Cardiovascular / Circulatory System • Nervous System • Muscular System

9. Organism • Several organ systems working together combine to make up an organism. • An organism is an entire living thing that can carry out all basic life processes. • Examples: • Human • Dog • Turtle • Tree

13. Organ Systems • The human body is made up of several organ systems. We will be discussing 7 in this class.

14. Respiratory System • Takes in oxygen and eliminate carbon dioxide

15. Circulatory System • Transport materials (gases and nutrients) to and from cells.

16. Digestive System • Breaks down food and absorbs nutrients.

17. Nervous System • Detects information from the environment and controls body functions.

18. Muscular System • Enables movement of body and internal organs.

19. Integumentary System • Protects the body from damage and the outside

20. Skeletal System • Supports and protects the body

21. A. Levels of Organization ORGAN SYSTEM CELL TISSUE ORGAN ORGANISM

22. Cell cells tissues organs organism

24. B. Matching Organ Systems • Circulatory – Red • Respiratory – Blue • Nervous – Yellow • Digestive – Green • Muscular – Orange • Skeletal - Purple

26. Organ System Mini-book • Instructions on p. 18 • You will be creating a mini book showing the organization in organ systems. • First you need to make your mini-book (follow instructions)

30. Organ Systems Quiz • The skeletal system has which of the following functions? • Takes in oxygen and eliminate carbon dioxide. • Detects information from the environment and controls body functions. • Supports and protects the body. • Enables movement of body and internal organs. • Which organ helps in the break down and absorption of nutrients? • the stomach • the femur bone • the brain • your foot • Which of the following systems transports nutrients and gases to the cells of the body? • digestive • circulatory • nervous • Integumentary • In humans, where does the exchange of oxygen and carbon dioxide take place? • HeartC. skin • OvaryD. lungs • Which of the following systems helps to control and coordinate the body's actions? • digestive • nervous • respiratory • circulatory
