1. Organization of the Human Body

2. Do Now There are 11 human body systems. Name as many as you can. As an added bonus, can you tell me what each system does? Winner gets a “Get out of Homework Free Pass”

3. The 11 Body Systems Digestive System Respiratory System Muscular System Circulatory System Nervous System Reproductive System Skeletal System Integumentary System Immune/Lymphatic System Excretory System Endocrine System

4. Homework Read Section 30.1 on P. 862 Define Epithelial tissue Connective tissue Nervous tissue Muscle tissue KNOW THE DIFFERENCE BETWEEN THE 4!

5. Human Body Systems Nervous System – Recognizes and coordinates the body’s response to changes inside and outside the body Integumentary System – Skin! Guards against infection and UV radiation. Regulates body temperature Immune/Lymphatic Systems – Protects body from disease

6. Human Body Systems Muscular System – Helps the skeletal system to produce voluntary movements. Helps circulate blood and move food through digestive system Circulatory system – Transports oxygen, nutrients and hormones to cells. Regulates body temperature. Skeletal System – Supports the body. Protects internal organs

7. Human Body Systems Respiratory System – Brings in oxygen needed for cellular respiration. Removes excess CO 2 Digestive System – Breaks down food, absorbs nutrients, eliminates waste Excretory System – Eliminates waste products from the body

8. Human Body Systems Endocrine System (hormones) – Controls growth, development and metabolism Reproductive System – Produces offspring. Females nurture and protect developing embryo

9. Organization of the Body Cells – Basic units of life, structure and function Tissues – Group of cells performing a specific function I.Epithelial Tissue II.Connective Tissue III.Nervous Tissue IV.Muscle Tissue Organs – Group of tissues that work to perform a single function Organ Systems – Group of organs that perform closely related functions EXAMPLE – Stomach and Large Intestines are apart of the Digestive System

10. Epithelial Tissue What does it do? Protects, absorbs and excretes materials Where can it be found? Skin, lining of digestive system, certain glands

11. Connective Tissue What does it do? Binding of epithelial tissue to structures, support and transport of substances Where can it be found? Under skin, surrounding organs, blood, bones

12. Nervous Tissue What does it do? Receives and transmits nerve impulses Where can it be found? Brain, spinal cord, and nerves

13. Muscle Tissue What does it do? Voluntary and involuntary movements Where can it be found? Skeletal muscles, muscles surrounding digestive tract, blood vessels and the heart

14. Homework Read Section 32.1 on P. 922 Label the blank skeleton with as many bones as you can Winner gets a prize (so don’t try and help each other out)

15. Flashcards! On one side, the type of tissue On the other side, its action and 1 place where it can be found in the human body
