The lungs and pulmonary system. Breathing is a vital process that allows our bodies to take in necessary oxygen and expel waste carbon dioxide. Air enters through the nose or mouth, journeys down the throat, and reaches the lungs via tubes called bronchi. These bronchi split into smaller tubes, bronchioles, ending in tiny air sacs known as alveoli.

- How does the the body know what to send down the esophagus and what to send down the trachea? I mean...Whenever you swallow something, the muscle contractions pull up on the hyoid bone, which draws the larynx up and tips the epiglottis backwards to c...
- What happens if food gets into your lungs and a blood cell tries to get it?There are certain cells in the lungs that have the job of keeping things clean there. These cells are called macrophages. If you happen to get smal...
- As the air keeps moving down the throat to the lungs, doesn't some air leak or escape? How efficient...Actually the efficiency of the respiratory system is very very efficient. Imagine a system of pipes; one pulls the air, another transfers it. Answe...
- Aren't the thin tubes called Bronchioli, not bronchiols? I did a project on the respiratory system f...i think that Bronchioli is technically correct, but the layman's pluralization is bronchiols.
- our body produces co2. does our body use them?Wonderful question! Yes! It does sound odd but CO2 is used in our body. It is used in synthesizing Urea (that's the excretory content of urine) fro...
- How do hiccups work?Hiccups are a spontaneous contraction of the muscle under the lungs called the diaphragm. They may occur in streaks. When the diaphragm contracts,...
- Why do we need two lungs? Can't we just have one big lung instead?I think it has a lot to do with surface area. Like the reason we are made up of many different cells versus one big cell. Absorption by little cell...
- Why are there a bunch of alveoli? Why can't we have one alveoli which is very large?While this does initially seem logical, this is inefficient to the point of being fatal. The reason for this is that the lungs exist to oxygenate t...
- Shouldn't the anterior tube be called the trachea, not the larynx? The larynx is the voicebox specif...The larynx and the trachea are two distinct anatomical structures. Both are part of the air way. The larynx starts with the hyoid bone and continue...
Meet the lungs! Breathing in through the mouth or nose, air travels down the throat, through the Adam's apple or voice box, and into the lungs. The lungs, which look like an upside-down tree, direct air to tiny sacs called alveoli. Oxygen from the air enters the bloodstream, while waste carbon dioxide exits into the alveoli and is exhaled.

- How can the food travel down into our organs if the diaphram is beneath the heart and the lungs?Food, after being chewed in the mouth, is swallowed and goes down the esophagus, which is a tube that runs parallel to the trachea. There is a junc...
- WEIRD QUESTION ALERT! So I honestly don't where to put this question, so I decided to put it here be...When we hiccup, the muscles in our diaphragm are contracting without our will. This happens when we eat or drink too rapidly, irritating the diaphr...
- Isn't the reason it's called an Adam's Apple is because in the Bible, Adam ate the Forbidden Apple?Apparently so... Although many may not believe, I have not the authority to impose on you your values and religion. More specifically, a piece of a...
- Larynx is another name for the voice box right?yes, Larynx is also known as the voice box.
- Where are the alveoli located and how many of them are there? Why does the oxygen have to go into th...The oxygen goes into the blood and is carried around the body to the cells, which use it and produce CO2 as a byproduct. The CO2 goes back into the...
- About the Adam's apple thing, it says that "Adam" is a boy's name, and it is called the Adam's apple...The name originated in the 1600's, and most likely referred to the Adam found in Abrahamic religions (Adam and Eve, first man and woman). A 1662 te...
- How does Cigarette smoking or tobacco affects our lungs and How does it cause cancer.Tobacco smoke contains more than 70 different cancer-causing substances. When you inhale smoke, these chemicals enter your lungs and spread around...
- What if you inhale pure oxygenInhaling high concentrations of oxygen can be ok for brief periods, but interestingly enough it can be toxic at high enough concentrations if expos...
- What causes the feeling of dread (when your heart "drops") to feel the way it does?When you're in a stressful or nerve-wracking situation, your brain releases the stress hormones, cortisol and adrenaline. These open up your bloods...

Oct 19, 2023 · The lungs replenish the body with life-giving oxygen. Learn about the anatomy of the lungs, how the organs make respiration possible, and how they are vulnerable to illnesses.
Inhaling and exhaling. Find out exactly why air goes in and out of the lungs. Discover how changes in lung volume affect air pressure, leading to the movement of air molecules in and out of the lungs. This process, crucial for respiration, is explained using a simple jar analogy.
