How can smoking effect the respiratory system and what illnesses can smoking cause?
Smoking affects the respiratory system because it stops the small little hairs in your throat from working as well these small little hairs are called Cilia and are used to push dirt and mucus out of your throat so it can be breathed out or swallowed when reaches top of throat. The tar also sticks to the lining of your throat and lungs (this is the stuff which makes fingers yellow etc.).Smoking is also known to make alveoli in the lungs a more round shape than small cauliflower shape. This decreases the surface area and results in less oxygen filling lungs again leaving you of breath. It also affects your respiratory system and circulatory system because it contains a lot of carbon monoxide which sticks to the haemoglobin in the blood instead of oxygen this means that many organs don't get enough oxygen as they should do so it increases blood pressure so any small amount of oxygen can reach organs anyway. This also means that less oxygen is swapped over in the gas exchange at the lungs which can often leave those who smoke out of breath quickly. Mucus which would also be removed through cilia goes in to blood stream and is deposited in arteries making them very fatty also increasing heart rate. All in all it also increases chances of lung diseases, strokes and heart failure etc.  (+ info)

How do the circulatory system, respiratory system and digestive system function together and how do they meet?

how do the circulatory system, respiratory system and digestive system function together and how do they meet in the body?

I would really like to know the answer to this question. I have checked myself and have yet to discover a detailed answer.

thank you very much.
Whoa....rather a complex question that requires an extensive answer to be complete and detailed. Even with my pretty good knowledge of anatomy I can't do it typing from memory.

Let me refer you to my anatomy bible. It is the classic 1918 Anatomy of the Human Body by Bartleby. Even haven been written in 1918....it is still accurate. The human body hasn't changed.

What causes sleep paralysis and night terrors?

---

I'm 16, and completely healthy and normal in all other regards, but for the last several years (since I was about 8 or 9) I've experienced sleep paralysis and night terrors, at the rate of about 1 or 2 times a month for the paralysis and more often for night terrors. Does anyone know what causes this?
Sleep paralysis is closely related to the paralysis that occurs as a natural part of REM (rapid eye movement) sleep, which is known as REM atonia. Sleep paralysis occurs when the brain awakes from a REM state, but the bodily paralysis persists. This leaves the person fully aware, but unable to move. In addition, the state may be accompanied by hypnagogic hallucinations. (strange shapes, faces, ect.)
some causes are:Sleeping in an upwards supine position
Irregular sleeping schedules; naps, sleeping in, sleep deprivation
Increased stress
Sudden environmental/lifestyle changes
A lucid dream that immediately precedes the episode. Also conscious induction of sleep paralysis is a common technique to enter a state of lucid dreams, also known as WILD .
Artificial sleeping aides, antihistamines
Recent use of hallucinogenic drugs
low levels of melatonin, a hormone. Usually, melatonin peaks at its highest levels in the middle of the night, but low levels, especially at night, preventing the stimulation of muscles, causing the body to not have the ability to move during dreams, and even when they wake up.

night terrors also have to do with REM sleep. In adults and children over the age of ten, they usually occure because of some sort of trauma the person has experienced.  (+ info)

Do respiratory therapists have to work in hospitals?

---

I'm still debating career choice, and respiratory therapist seems kind of interesting. I don't really want to work in a hospital though. I wouldn't be good under pressure in the ER and stuff.

Do RT's working in other settings, such as calm doctor offices and stuff like that?

Thanks!
Resp therapists work in nursing homes and home health agencies. It is a very rewarding career.Usually not needed in doctor's offices. Good luck.  (+ info)

Help for cleanest breathing conditions - things I can do at home for respiratory health?

---

I have been fighting a respiratory battle for over a month - just got out of the hospital and now need to keep my surrounds and activities and such as healthy/clean, non irritating as humanly possible for a few weeks at least. Any suggestions are welcome. Thanks.
And air filtration system, but I think they run pretty high. Maybe you can rent one for a couple of weeks until you feel better. In the meantime, stay away from smokers, keep your house dust free, and remove anything that you might be allergic to such as flowers or plants.   (+ info)

Why do I suffer from sleep paralysis during naps?

---

Every single time I take a nap I suffer from sleep paralysis. I am half awake when I start hallucinating, have trouble with my breathing, feel pressure on my chest and of course, i feel like I am paralyzed.

My question is, why is it that I only suffer from it when I am napping, not when I am sleeping through the night?
That used to happen to me too.

One thing I noticed was that if I napped when I was stressed/burnt out, I'd have s.p. sometimes 2 or 3 times in a row.

The second thing I noticed was that a lot was going on outside of my house when I took naps..... I live on a busy street. I'd open my eyes feeling paralyzed and stuck right when someone was walking pass my window having a conversation or something. Instead of struggling to move, I was struggling to yell shut up. Which is funny because I'd never yell at anyone for walking pass my window if I had fully woke up.

I now sleep with either earplugs or listen to binaural tones while sleeping. Those calm me down or at least block out outside noise, which I thought triggered these s.p. episodes. It works more than it doesn't  (+ info)

Is it bad to experience sleep paralysis every night?

---

What causes hypnagogic hallucinations and sleep paralysis?

---

I get these very severely while I fall asleep often. Loud voices in my ears, almost like someone's tuning through a radio really quickly. It only happens before I fall asleep.

I also get sleep paralysis on a regular basis -- I wake up and for a few moments (though sometimes it feels like hours) can't move my body.

Are these two related? What causes them?
The fact that you know the names of these phenomena tells me you must already know something about narcolepsy.

There are two different kinds of sleep (REM and nonREM); these two states are as different from each other as either is from the awake state. So, there are three basic states of conciousness. In narcolepsy, the boundaries between these states are leaky. Why this happens is largely unknown, although some genetic associations have been uncovered.

You are at fairly high risk of developing sleep attacks and cataplexy. At the very least, you should make sure to avoid sleep deprivation. Ask your primary doctor to refer you to a sleep specialist.  (+ info)

How do you test your cardio respiratory endurance?

---

Im doing a powerpoint on some health related components and i need to know how to test your cardio respiratory endurance.
There are some tests, such as the cardiopulmonary index, are quite simple, while others are very complicated and may use formulae with up to 100 physiological indicators e.g. Cureton's tables. All the tests involve comparing physiological measurements during rest with those directly after exercise, and after a specified recovery period.

If I simplify the whole testing methodology, I prefer the following easy ones:

* 1.5 mile run test
* 1.5 mile walk test
* 3 minute step test
* treadmill test

You can read more about this at the blog post too.  (+ info)

What type of science classes do u have to take to become a respiratory therapist?

---

Im lookin into being a respiratory therapist, but im not a big fan of chemistry or calculus? Are these necessary?
I am a first year RT student. It is going to depend on what school you go to, I didn't have to take calculus but had to have college algebra. I did have to take Intro to Chemistry, it is pretty basic but as I said it depends a lot on what school you go to.  (+ info)
