1 Respiratory System & Excretory / Urinary System

2 The Respiratory System

3 Glucose + Oxygen = Carbon Dioxide + Water + Energy
Breathing and Respiration Cellular Respiration – Cells using oxygen and glucose to make energy. Glucose + Oxygen = Carbon Dioxide + Water + Energy


5 OXYGEN CARBON DIOXIDE Handout of cycle Simple Story….. Ted Ed

6 The Functions of the Respiratory System
1. Moves oxygen into the body for blood to carry to cells to make energy in mitochondria. 2. Moves carbon dioxide through the blood out of the body as waste from respiration.

7 Respiratory Animation
Using your template, follow the pathway of oxygen as it is inhaled into your nose and mouth and enters your bloodstream. Or Fill in the blank on the respiratory system Respiratory Animation

8 Using the following slides and your textbook pages 272 – 274…
Using the following slides and your textbook pages 272 – 274….. Explain the function of each organ listed on your template as air/oxygen enters the body, moves into your respiratory system, and enters your blood.

9 1. Oxygen into Nose / Mouth
Path of Air…. 1. Oxygen into Nose / Mouth Nasal cavity - moistened and warmed Mucus - traps dust, pollen, and other materials Cilia -Tiny, hair-like structures trap material Sneezing

10 2. Pharynx (Throat) 3. Epiglottis 4. Trachea (windpipe)
passageway used for food, liquid, and air. 3. Epiglottis flap of tissue over the trachea to keep food from going into lungs 4. Trachea (windpipe)

11 5. Bronchi 6. Bronchioles 2 short tubes that carry air into each lung.
bronchi branch into smaller tubes in lungs Fun Fact (FF):(As small as hair / 30,000 in each lung!!) Coughing

12 2 organs where gases are exchanged.
7. Lungs – 2 organs where gases are exchanged.

13 Diaphragm Observation
Diaphragm - a muscle beneath lungs that contracts and relaxes to help move gases into and out of your lungs. Hiccup – spasm in your diaphragm. Diaphragm Observation

14 Fluid from pneumonia, cystic fibrosis, etc.
8. Alveoli Air sacs in the lungs where gases are exchanged by diffusion. Fluid from pneumonia, cystic fibrosis, etc. Fun Fact (FF) :The total surface area of the alveoli (tiny air sacs in the lungs) is the size of a tennis court MILLION in EACH lung!!

15 Breathing and Speaking
Larynx – voice box Air passes past the 2 vocal chords that produces your voice…!

16 Forcing air between the cords causes them to vibrate and produce sounds.

17 Respiratory Infections Identify the effects of the following on the respiratory system: common cold bronchitis asthma

18 Respiratory Infections
Common cold - upper part of the respiratory system – pharynx, larynx, trachea, and bronchi.

19 Bronchitis - bronchioles are irritated and swell, too much mucus is produced.

20 Asthma - Shortness of breath, wheezing, or coughing
Asthma - Shortness of breath, wheezing, or coughing. The bronchial tubes contract quickly.

21 Smoking and the Respiration System
Tar, carbon monoxide, and nicotine damage lung tissue and alveoli. Carcinogens - substances that can cause an uncontrolled growth of cells / cancer.

22 Diseases and Disorders of the Respiratory System
Even if you are a nonsmoker, inhaling smoke from tobacco products—called secondhand smoke—is unhealthy and has the potential to harm your respiratory system.

23 Emphysema A disease in which the alveoli in the lungs enlarge .
Alveoli can’t work. Less oxygen moves into the bloodstream from the alveoli. Blood becomes low in oxygen and high in carbon dioxide, shortness of breath occurs.


25 Lung Cancer Inhaling the tar in cigarette smoke is the greatest contributing factor to lung cancer. .

26 Unhealthy Respiratory System and Its Effects on the Circulatory System
Smoking chemicals get into blood Carbon monoxide takes the place of the oxygen molecules in the blood Circulatory system is strained as it tries to get oxygen to cells Veins, arteries, and capillaries are irritated Smokers more prone to heart disease & heart attacks

27 Smoking, Tobacco, and Your Body15

28 The Excretory (Urinary) System

29 Excretory / Urinary System

30 The Function of the Excretory System
Filters blood collecting and removing waste.

31 Identify the function of:
Kidneys Nephrons Ureters Bladder Urethra

32 The Kidney Kidneys - Removes UREA (waste) from the blood, and return clean blood back to the body. Fun Facts (FF): -Every minute, about 1 liter of blood enters the kidneys. That's about one-fifth of all the blood in your body!

33 FF:1 Million in Each Kidney!!
In the Kidney are… Nephrons – - filter the blood - produce urine. -control the amount of water in the body. FF:1 Million in Each Kidney!!

34 and lungs (exhaling water vapor)!!
Ureters – carry urine to the bladder Bladder –stores urine. Urethra – tube where urine flows from the body. Also help ……….. liver (produces urea), skin (sweating), and lungs (exhaling water vapor)!!
