Respiratory System

Use of accessory muscles on inspiration (e.g., in patients with COPD, asthma, thoracic scoliosis, and ankylosing spondylitis).

The air pressure changes inside and outside the body, breathing takes place.In normal conditions,air moves from high pressure area to low pressure are.

The immune system reacts to substances as threats to the body health. When the allergens are inhaled the first response of the immune system is to attack and attempt to stop the particles from harming the body.

Mucus in the nose helps trap particles entering the respiratory system. The hairs/cilia of the respiratory system also filter incoming air.

• As you all know, respiratory therapy is still a fairly new profession. Whereas doctors and nurses have been around for centuries, respiratory therapists for about half a century. I like the fact that I am going to be a part of something that is growing and trying to gain further recognition.
• Perhaps the most obvious reason is that I can't think of anything more rewarding that I'd enjoy doing besides helping someone breathe easier. To say that I will be the one managing the patient's respiratory care feels good. After all, if you're not breathing, you're not doing anything else.
• I enjoy the technical aspect of working with ventilators, BiPAP, and so on. I've always been pretty tech savvy and mechanical, but I also knew that I want to work in the medical field. Respiratory therapy seems to be a pretty good profession for me because I get the "best of both worlds." Not only do I get to troubleshoot equipment, but I also get to take care of people.
• The title of my blog gives this one away, but I am basically what I'd called addicted to critical care. I was drawn to respiratory therapy partly because of the level of care of the patients that they take care of, and I really want to be able to work in the ER or ICU, preferably in a Level I trauma center. I like that RT school trains you to critically think and care for patients requiring urgent care.
• I like the variety. It is interesting to me that I will one day be working with all kinds of patients, from peds to the elderly, from subacute patients to the critically ill.
• Another reason I want to be an RT is the fact that therapists provide advanced therapy and usually rely a great deal on independent judgement.
• The final reason I can think of right now is that I'd like to be a part of the healthcare team providing care to patients. RTs work with nurses, physicians, and other healthcare staff to decide what is best for the patient, and I really would like to be a part of that team.

Normal relaxed breathing is referred to as tidal volume. This is produced by the action of the diaphragm muscle only. It is also referred to as diaphragmatic breathing and is associated with a relaxed state.

At the end of the electron transport chain in the mitochondria, electrons are donated to oxygen (O2), which combines with hydrogen ions to form water. Without the O2 molecules to accept the electrons, the electron transport chain couldn't function.

When we breathe in the intercostal muscles in the rib cage contract and the chest inflates, while filling up with air, at this point the diaphragm flattens. The oxygen then goes down the trachea and through the bronchiole tubes and into the lungs, where it meets the alveoli. The Oxygen in the alveoli then diffuses through the alveoli and through the capillaries in the lungs. The capillaries are only one cell thick, thus making it easier for the oxygen and carbon dioxide to diffuse through. The carbon dioxide diffuses through, in the other direction from, the capillaries to the alveoli, where it can leave the body via the bronchiole tubes, trachea and exiting out the mouth. When we breath out, the diaphragm relaxes and goes back into the dome shape, the intercostal muscles also relax, allowing the chest to deflate.

Using the formula from wikipedia, the RQ of ethanol calculates to 0.66 .

The molecular formula for ethanol is C2H6O. Using the above mentioned formula (see http://en.wikipedia.org/wiki/Respiratory_quotient#Calculation) the RQ is x/ (x + y/4 - z/2)= 2/(2 + 6/4 - 1/2) = 2/3 = 0.66 .

I advise you to download this book, it talks about healthy food, exercises and how to deal with stress

The mucus layer protects the respiratory tract by trapping bacteria and dust, not allowing them to enter the body. Mucus filters the air during inhalation and keeps the tissues from becoming too dry.

- I'm not sure I understand what you are asking. A tidal volume is what we use to measure how many liters a person can hold in their lungs. It's normally about 10-15mls/kg of ideal body weight. That number can be used to identify certain respiratory diseases. Its also what most ventilators are set on when a person needs ventilatory support.

There is exchange of CO2 and O2 in the lungs of aerobic vertebrates. The process is generally referred to as gas exchange. It depends on what organism you're talking about. It could be the skin, gills, lungs, or any other structure. In the lungs is the Alveoli.

Being Ill ca. influence it pretty well.

In the respiratory system, we see the exchange of gases. In this gas exchange, carbon dioxide (CO2) leaves the blood and goes into air in the lungs, and oxygen (O2) leaves the air in the lungs and goes into the blood. It is this gas exchange, which occurs in the alveoli, that permits oxygenation of the blood and keeps us alive.

AIR SACS are the FUNTIONAL UNIT of human respiratory.

while we regard ALVEOLI as STRUCTURAL UNIT of human respiratory system.

The muscular system uses the bones for their action. Without bones muscles would be useless at distance. Bones act like lever arms to increase the force produced by muscles. The digestive system gives nutrients to the muscles.

The circulatory system!
