1 Objective: SWBAT identify the hierarchy of organization in living things WARM UP: Add all INTERNAL (inside) organs of your body. Don’t look in your textbook! Intro to Body Systems

2 Compare Look at your group members drawings What things did they include that you did not include? What did you include that they did not? body/parts/16-unusual-facts-about-the- human-body.htm

3 Don't stick out your tongue if you want to hide your identity. Similar to fingerprints, everyone also has a unique tongue print! Your pet isn't the only one in the house with a shedding problem. Humans shed about 600,000 particles of skin every hour. That works out to about 1.5 pounds each year, so the average person will lose around 105 pounds of skin by age 70

4 An adult has fewer bones than a baby. We start off life with 350 bones, but because bones fuse together during growth, we end up with only 206 as adults. Did you know that you get a new stomach lining every three to four days? If you didn't, the strong acids your stomach uses to digest food would also digest your stomach.

5 The small intestine is about four times as long as the average adult is tall. If it weren't looped back and forth upon itself, its length of 18 to 23 feet wouldn't fit into the abdominal cavity, making things rather messy

6 This will really make your skin crawl: Every square inch of skin on the human body has about 32 million bacteria on it, but fortunately, the vast majority of them are harmless

7 The source of smelly feet, like smelly armpits, is sweat. And people sweat buckets from their feet. A pair of feet have 500,000 sweat glands and can produce more than a pint of sweat a day.

8 Blood has a long road to travel: Laid end to end, there are about 60,000 miles of blood vessels in the human body. And the hard-working heart pumps about 2,000 gallons of blood through those vessels every day

9 You may not want to swim in your spit, but if you saved it all up, you could. In a lifetime, the average person produces about 25,000 quarts of saliva -- enough to fill two swimming pools!

10 If you're clipping your fingernails more often than your toenails, that's only natural. The nails that get the most exposure and are used most frequently grow the fastest. Fingernails grow fastest on the hand that you write with and on the longest fingers. On average, nails grow about one-tenth of an inch each month.

11 Organization of Living Things Made up of many parts that work together Cells  Tissues  Organs  Organ Systems  Organism Example: Muscle Cell  Muscle Tissue  Heart Muscle  Cardiovascular System  Human

12 Cell Cell: Basic unit of life and makes up all living things

13 Tissue Tissue: Group of similar cells that work together

14 Organ Organ: made up of 2 or more types of tissue that work together

15 Organ System Organ System: group of organs that work together to perform a function

16 The Body Systems Skeletal (bones) Muscular (muscles) Urinary (also called Excretory) Circulatory (heart and blood) Respiratory (breathing) Digestive Integumentary (skin) Nervous (brain, nerves) Endocrine (hormones) Reproductive The Immune System works with many systems

17 Human Body Vocab Terms List Use the ipads and textbooks to find definitions. Use the website Finished? Go to the below website and explore the body systems

18 Vocabulary Sheet- Did you finish it? If so, do some exploration with the pink QR codes on the wall! What are some good expectations for using devices in class? Table leaders- what did your group say? Are there any questions?

19 QR Codes Explore the websites Code # Main Idea of the Website
