Respiratory Intro You 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? Nasal Passage Here We Go!!! Tongue Pharynx Bronchi Tubes Alveoli (air-sacs) Thin-walled blood vessels called capillaries Very thin cells line the alveoli so that O2 and CO2 can pass in and out of the blood. Bronchioles pass air to and from your alveoli. The Trachea is held open by partial rings of cartilage. Tongue Pharynx Where are we? Here We Go!!! JH

Picture Intro Here is a overview picture of the Respiratory System. Just go to the next slide to see it. MB

Welcome The Respiratory System Now we will begin our tour. Welcome to… MB

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

The Nose and Mouth When the air comes into your nose it gets filtered 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 moisten and heat the air that you breath. Air can also get into your body through your mouth/oral cavity but air is not filtered as much when it enters in through your mouth. MB

Bronchioles pass air to and from your alveoli. The Trachea is held open by partial rings of cartilage. Tongue Pharynx We are here. MB

The Pharynx and Trachea Next 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 Trachea (Throat) Mouth Trachea Your 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 rings of cartilage.” Without these rings your trachea might close off and air would not be able to get to and from your lungs. MB

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

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

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

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

Looking at the Alveoli Lets take a closer look shall we. JH

Contiguous Basal Laminae (Membrane*) Oxygen Diffusion Carbon Dioxide Oxygen diffuses through the membrane into the blood stream. Carbon Dioxide diffuses through the membrane and enters the alveolus. Alveolus Contiguous Basal Laminae (Membrane*) Capillary * A specialized thin layer of skin that oxygen and carbon dioxide can pass through. JH

Intro to Diaphragm Now 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 Diaphragm JH

Here is an experiment that you can try. Diaphragm Experiment JH

Experiment Instructions 1st 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. Experiment Instructions 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

Key Words Respiratory 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.
