Respiratory IntroYou may be asking, what is the Respiratory system? Well, the Respiratory system is the system that helps you breath in and out, so oxygen (02) can be pumped through your body and carbon dioxide (CO2) can be removed from the blood stream. You must remember that the Respiratory system is made up of many different organs. JH

Where are we?Here We Go!!!JH

Picture IntroHere is a overview picture of the Respiratory System.

Just go to the next slide to seeit.

Respiratory Overview PictureMB

WelcomeNow we will begin our tour.

Welcome toMB

The Nose and MouthThis is where it all begins. This is where the oxygen first enters your body and also where Carbon Dioxide leaves.MB

The Nose and MouthWhen the air comes into your nose it getsfiltered by tiny hairs and it is moistened by the mucus that is in your nose.

Your sinuses also help out with your Respiratory System. They help to moistenand heat the air that you breath.

Air can also get into your body through yourmouth/oral cavity but air is not filtered asmuch when it enters in through your mouth. MB

Where are We?We are here.MB

The Pharynx and TracheaNext we will head down to your pharynx(throat) and your trachea (windpipe).This is where the air passes from your nose to your bronchi tubes and lungs.MB

The Pharynx and TracheaYour pharynx (throat) gathers air after it passes through your nose and then the air is passed down to your trachea (windpipe). Your trachea is held open by incomplete ringsof cartilage. Without these rings your trachea might close off and air would not be able to get to and from your lungs.MB

Where are We?We are here.MB

The Bronchi Tubes and Bronchiole IntroYour trachea (windpipe) splits up into two bronchi tubes. These two tubes keep splitting up and form your bronchiole.MB

The Bronchi Tubes and BronchioleThese bronchi tubes split up, like tree branches, and get smaller and smallerinside your lungs.The air flows past your bronchi tubesand into your bronchiole. These tubes keep getting smaller and smaller until theyfinally end with small air sacs (called alveoli).But we will go there later MB

The Alveoli and Capillary NetworkNow we will head over to the alveoli and what happens when theair finally makes it down there.MB

The Alveoli and Capillary NetworkYour alveoli are tiny air sacsthat fill up with air/oxygen when you breath in.Your alveoli are surrounded bymany tiny blood vessels calledcapillaries. The walls of your alveoli (and capillaries) are so thin that the oxygen or carbon dioxide can pass through them, traveling right into, orout of your blood stream.MB

Intro to DiaphragmNow we will look at the Diaphragm. You might be wondering, what does the Diaphragm do? The Diaphragm is an important factor in breathing. JH

Diagram of DiaphragmJH

Here is an experiment that you can try.Diaphragm ExperimentJH

Experiment Instructions1st you need a bottle that you can sacrifice to cut up. 2nd you cut the bottom of the bottle and put a big balloon on the bottom.3rd get a rubber cork ( make sure it blocks the hole)and put a hole through it ( top to bottom). Insert a thin tube into the cork and place a balloon on the bottom of the tube.4th make sure the thing is airtight.JH

Respiratory Overview ReviewCO2JHThe Pharynx, or throat, is located where passages from the nose and mouth came together.Air Passing over the mucus membrane of the nasal cavity is moistened, warmed, and filtered Inside the lungs the Bronchi branch into small tubes called bronchiolesAt the end of the bronchioles are bunches of alveoli, air sacs, arranged like grapes on a stemAir enters the trachea, or wind pipe which leads to and from the lungsThe trachea divides into two tubes called bronchiIf one lobe is injured or diseased, the other lobes may be able to function normally

Fun Facts * At rest, the body takes in and breathes out about 10 liters of air each minute. * The right lung is slightly larger than the left. * The highest recorded "sneeze speed" is 165 km per hour. * The surface area of the lungs is roughly the same size as a tennis court. * The capillaries in the lungs would extend 1,600 kilometers if placed end to end.* We lose half a liter of water a day through breathing. This is the water vapor we see when we breathe onto glass. * A person at rest usually breathes between 12 and 15 times a minute. * The breathing rate is faster in children and women than in men.

Key WordsRespiratory System- The group of organs in your body that are responsible for taking in Oxygen and breathing out the Carbon Dioxide which is the waste product of cellular respiration.Oxygen-The gas that your body needs to work and function.Carbon Dioxide- The waste product (gas) that is produced through respiration of people and animals.Nose/Nasal Cavity- Where Oxygen first enters your body. Tiny hairs help filter the air and air is moistened and heated by your nose. Your Nose leads into your Nasal Cavity.Mouth/Oral Cavity- Oxygen/air can also enter through your Mouth but it is not filtered. Your Mouth opens up into your Oral Cavity.Sinus- A cavity in the bones of your skull that helps moisten and heat the air that you breath.Pharynx/Throat- Gathers air from your Nasal and Oral Cavities and passes it to your Trachea.Trachea/Windpipe- A tube like pathway that connects your throat to your Bronchi Tubes and lungs. Air passes through it when it travels from the Pharynx to the Bronchi Tubes.

Key Words Cont.Bronchi Tubes- Each tube (one per lung) splits up into many smaller tubes called Bronchiole, like branches on a tree.Bronchiole- Keep splitting up until they reach your Alveoli.Respiratory Bronchiole- The air-tubes that are actually connected to the Alveoli.Alveolar Duct- The final tube, which is part of the Alveoli, that leads to the air-sacs.Alveolar Sac- Where the chemical change takes place and where blood cells pick up oxygen and drop off carbon dioxide.Alveoli- Tiny air-sacs at the end of your Alveolar Duct. They fill up with Oxygen and are surrounded by Capillaries.Capillaries- Tiny blood streams (around one cell wide) that surround your Alveoli. They take Oxygen out of our Lungs and replace it with Carbon Dioxide, which you later breath out.Diaphragm- The muscle membrane that helps you breath in and out by changing the pressure in your chest cavity.

IntroductionThe Circulatory System is the main cooling and transportation system for the human body The body has about 5 liters of blood continuously traveling through it by way of the Circulatory System In the Circulatory System, the heart, lungs, and blood vessels have to work togetherThe Circulatory System has three different parts: pulmonary circulation (lungs), coronary circulation (heart), and systemic circulation, (the rest of the systems processes).

The HeartThis organ is what pumps oxygen rich blood, nutrients, hormones, and the other things your body needs to maintain your health, to your organs and tissues.The pulmonary veins you see on the right side of the diagram come from your lungs, where the blood cells collect oxygen. Its then pumped out to the rest of the body through the Aorta (Top). All of the blue sections show blood cells carrying waste, (C02) moving back to the lungs (where the C02 will be replaced by oxygen) through the Pulmonary Artery (Top, blue)Pulmonary VeinsPulmonary Artery(Inferior Vena Cava) From the Body(Aortic Artery) To the bodyWhenever the blood is pumped from one section of the heart another a valve closes behind it preventing the blood from moving backwards.By The WayValves: (tricuspid valve semilunar (pulmonary) valve, bicuspid (mitral) valve, and the semilunar (aortic) valve(Superior Vena Cava) From the Body

Blood Flow through HeartBlood from the body travels into the right atrium, moves into the right ventricle, and is finally pushed into lungs in the pulmonary arteriesThe blood then picks up oxygen and travels back to the heart into the left atrium through the pulmonary veinsThe blood then travels through the to the Left Ventricle and exits to the body through the Aorta Right AtriumLeft Atrium

Blood Flow to ArmsOxygen rich blood leaves the heart and travels through arteriesIn the capillaries the oxygen and food is given to the bodys cellsThe blood finally travels back through veins to the heart to pick up oxygenARTERIES- FROM HEARTCAPILLARIESVEINS- TO HEART

A red blood cell then travels from the heart through arteries that eventually branch into the bodys vast system of capillaries (microscopic blood vessels which connect arteries and veins), they eventually lead toPulmonary VeinAortaBrachial ArteryRenal ArteryRedial ArteryUlnar ArteryIliac ArteryPath to the Exchange

The ExchangeWhen the itty bitty teeny tiny red blood cells pass the desired tissue they.TRANSACTThe oxygen the blood cells are carrying is given to the bodys tissue.And the CO2 (waste) from the tissue is given to the same blood cell to be exhaled.TissueTissueTechnically the Hemoglobin in the blood (a substance full of iron) attracts oxygen from the lungs. The red blood cell then carries it to the desired tissue. Because this tissue has a high CO2 count the hemoglobin lets go of its oxygen and collects the carbon dioxide. You see the hemoglobin has an affinity for whichever gas has a greater count. Because the tissue has a large amount of built up waste (CO2) the hemoglobin attracts it and then replaces it with oxygen, and vise versa in the lungs.How It WorksOxy-Rich Blood CellOxy-Poor Blood CellNow lets travel to the legs!!!

Blood Flow to LegsApproximately 500 ml of blood moves from the heart and lungs down to the legs when a person stands up after lying down

The oxygen rich blood cells then travel through the capillaries where yet another!FUN FACT!

The oxygen and CO2 are exchangedin the cellsOxygen RichOxygen RichOxygen PoorOxygen PoorTissueDont forget that the Hemoglobin in the blood cells let go of the cells oxygen because of the large CO2 (waste) count in the tissue.Gas Exchange Occurs,Now lets go back to the heart!!!

Circulation back to HeartCapillaries carry the blood toVenules that connect to veins and theVeins (wide blood vessels) carries the oxygen-poor blood back to the heart.

Conclusion As you have learned (Hopefully) the Circulatory System is one of the most important systems in the human bodyIt is the only reason youre still alive todayand you can attribute the cooling down, feeding of and protection of your body to it.So the next time you bust open your leg skateboarding you can thank your Circulatory System for patching you up.
