Respiratory System

they breath through their gills and they breath out like us but the only difference is that they have gills and lungs.

The nose, larynx and lungs belong to the respiratory system

beta oxidation is the breakdown of fatty acids..occurs in mitochondria

the organ that is involved in gas exchange is the lung.

the specific lung structure that is the site for gas exchange is the alveolus which is part of the alveoli, which is found in the lung.

The air we breath in is roughly 21% O2 and 0.04% CO2 and we breath out air that is 16% O2 and 4% CO2

This is such a broad question. The respiratory system is prone to many ailments. The treatments will differ based on the ailment and the severity. Respiratory ailments range anywhere from common cold to tension pneumothorax. Perhaps the most common ailments are COPD related. Things such as emphysema, bronchitis, and asthma. All three ailments require some sort of bronchodilator or sympathomimetic such as albuterol or epinephrine. In the field, we can administer SVN, or small volume nebulizer masks to relax the passages (bronchioles) in the lungs.

destruction in the air sacks distal to the terminal bronchiol or in simple term the destruction of alveoli. The chest usually become hyperinflated due to the excessive action of sucking the air in due to the obstruction

The respiratory system functions in gas exchange. In doing so, it works closely with the circulatory system, and is aided by the nervous, muscular and skeletal systems.

pulmonary ventilation and external respiration

veins,arteries,windpipe,and lungs.The lungs count as one.

I guess you refer to the pulmonary valve stenosis which usually is due to the valve calcification when less blood supply will go from right ventricle of heart to the pulmonary circulation. The right ventricle will be hypertrophied because it's working harder then before.

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 .
