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 systemRespiratory 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 / MouthNasal cavity - moistened and warmedMucus - traps dust, pollen, and other materialsCilia -Tiny, hair-like structures trap materialSneezing
10 2. Pharynx (Throat) 3. Epiglottis 4. Trachea (windpipe) passageway used for food, liquid, and air.3. Epiglottisflap of tissue over the trachea to keep food from going into lungs4. 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 boxAir passes past the 2 vocal chords that produces your voice…..cool!
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 CancerInhaling 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 bloodCarbon monoxide takes the place of the oxygen molecules in the bloodCirculatory system is strained as it tries to get oxygen to cellsVeins, arteries, and capillaries are irritatedSmokers more prone to heart disease & heart attacks
30 The Function of the Excretory System Filters blood collecting and removing waste.
31 Identify the function of: KidneysNephronsUretersBladderUrethra
32 The KidneyKidneys - Removes UREA (waste) from the blood, and return clean blood back to the body.Fun Facts (FF):-Every minute, about 1 liter ofblood enters the kidneys.That's about one-fifth ofall 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 bladderBladder –stores urine.Urethra – tube where urine flows from the body.Also help ………..liver (produces urea),skin (sweating),and lungs (exhaling water vapor)!!
