2. Returning papers
Please have a student pass out the papers marked as Excretory Model papers. They matched the 6 boxes to show the process. We actually did these together in class, but they have been checked and can be returned to their owners.

3. Organs are organized into ORGAN SYSTEMS!
Review
Organs are organized into ORGAN SYSTEMS!
An ORGAN SYSTEM is a group of organs that work together to perform a major job.
Examples:
Circulatory System
Digestive System
Skeletal System
ORGAN SYSTEM
ORGANS
TISSUES
CELLS

5. The Digestive System (Flip to the back of your notes)
Review
The Digestive System (Flip to the back of your notes)
The digestive system has 3 main functions:
It breaks down food into particles that the body can use.
It absorbs nutrients into the blood.
It eliminates waste from the body.
Mouth
Esophagus

6. Categories of NUTRIENTS
Review
Categories of NUTRIENTS
Water - most important because other stuff can dissolve into it. “Water soluble”
Minerals
Vitamins
Fat
Carbohydrates
Proteins
** You may need to write the list on your notes.**

Excretory System
Fluid’s

9. Main Function:
REVIEW
The system of the body that collects waste produced by cells and removes the wastes from the body. (also known as: excretion)

10. Structures of the excretory system
REVIEW
Structures of the excretory system
Kidneys – (2) filter blood
Ureters – 2 narrow tubes that leading from the kidneys to the bladder
Urinary Bladder-fist sized pouch (muscular sac) that holds about 2 cups of urine
Urethra – exit tube

11. Homeostasis with Excretion
REVIEW
Excretion maintains homeostasis by keeping the body’s internal environment stable and free of harmful levels of chemicals.
Kidneys
Lungs and Skin
Liver

12. What does it do for us? REVIEW Our circulatory system…
Delivers necessary materials (like oxygen and sugar) to the entire body in the blood,
Removes waste products from cells, and
Helps fight disease by transporting immune cells in the blood.

14. What carries the blood? REVIEW
BLOOD VESSELS are the hollow tubes that carry your blood around your body.
There are 3 TYPES:
ARTERIES
CAPILLARIES
VEINS

15. What is your blood? REVIEW Red Blood Cells carry oxygen.
White blood cells fight disease.
Platelets form blood clots to stop you from bleeding too much.

17. New notes – Respiratory System
Listen and follow along.
Fill in your notes on the worksheet provided.

18. What is the RESPIRATORY SYSTEM?
- Breathe in and out…
What is the RESPIRATORY SYSTEM?
The system of the body that deals with BREATHING.
It consists of the NOSE, PHARYNX, TRACHEA, BRONCHIAL TUBES, and LUNGS.

19. What is the FUNCTION of the Respiratory System?
- Breathe in and out…
What is the FUNCTION of the Respiratory System?
To DELIVER OXYGEN to the body.
To REMOVE CARBON DIOXIDE from the body.

20. Why does the body need oxygen?
- Breathe in and out…
Why does the body need oxygen?
The body’s CELLS use OXYGEN to release ENERGY to the body.
CELLULAR RESPIRATION is the CHEMICAL REACTION that uses GLUCOSE & OXYGEN to release ENERGY.
CARBON DIOXIDE is a WASTE PRODUCT of this chemical reaction.

21. Which systems work together?
- Breathe in and out…
Which systems work together?
RESPIRATORY SYSTEM gets OXYGEN from the air.
DIGESTIVE SYSTEM gets GLUCOSE from food.
CIRCULATORY SYSTEM DELIVERS oxygen and glucose to cells.
In the cells, respiration uses glucose and oxygen to release ENERGY.

22. What path does AIR flow? Try it
Use the words on your table (green slips) and work with your elbow partner to put them in order.
Raise your hand when you are done.
You should have five slips (bronchial tubes, pharynx, trachea, nose, lungs).
Paper clip them back together (out of order) when the teacher asks you to clean.

23. What path does AIR follow?
- Breathe in and out…
NOSE
PHARYNX
TRACHEA
BRONCHIAL TUBES
LUNGS (alveoli)

24. What happens in each part?
- Breathe in and out…
NOSE – in the nasal cavity,
the air is:
Warmed,
FILTERED, and
moistened.
(Mucus and nasal hairs keep out
dust, pollen and other particles).
PHARYNX – air passes through the THROAT when breathing. The EPIGLOTTIS covers the trachea when you SWALLOW to prevent FOOD from entering the trachea when you eat/drink.

25. What happens in each part?
- Breathe in and out…
TRACHEA – is the WINDPIPE that leads to the lungs. It is a TUBE with RINGS OF CARTILAGE.
BRONCHIAL TUBES – are the
the short tubes that branch off the
trachea TO CARRY AIR TO
the LUNGS.

26. What happens in each part?
- Breathe in and out…
LUNGS – inside the lungs, the bronchi branch into SMALLER TUBES. At the end of the smallest tubes, are structures called ALVEOLI.
ALVEOLI – are AIR SACS, surrounded by CAPILLARIES.
This where BLOOD picks up
OXYGEN and gets rid of CARBON
DIOXIDE.

27. What happens in the ALVEOLI?
Not on the notes worksheet, but good to read through.
- Breathe in and out…
What happens in the ALVEOLI?
GAS EXCHANGE - Blood from the body enters the lungs. In the alveoli, the blood GETS RID OF CARBON DIOXIDE and PICKS UP OXYGEN before returning to the heart to take oxygen to rest of the body.

28. How do we BREATHE?
Link ( - sometimes doesn’t work, can be skipped. I just discuss how the diaphragm (the large, dome-shaped muscle under the lungs) contracts to pull down and expand the chest/lung area. This allows air into the lungs. When it relaxes, the chest cavity is compressed and air in the lungs is pushed out.

29. How are BREATHING & SPEAKING related?
Air that you BREATHE OUT when you exhale also helps you SPEAK.
Your LARYNX is your VOICE BOX which has 2
VOCAL CHORDS that move and
produce sound when air passes
through the opening between
them.
Larynx

Watch the video on Respiratory System (the class can watch it more than one time)
Take the quiz. 10 multiple choice questions.
I will include paper copies of the respiratory system quiz from BrainPop, but it’s okay if you prefer to just go through the questions as a class – having students raise a hand to answer. Just let me know so I’m not looking for a quiz grade when I return.

31. Teen files video Smoking: Truth or Dare video
To be watched on Friday! Click here to reach the youtube video.
If you need more to do, feel free to get started on the video – they can just “re-see” some on Friday. There will be a field trip on Friday – so some may be missing.

32. 4th period only
4th needs to hear/see the afternoon announcements. I’ve asked Destiny B and Muntasir to help with the computer as needed.
Link to the announcements here – or use a google window to open.

33. Are there any questions?
