How can smoking effect the respiratory system and what illnesses can smoking cause?

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.


If the information you need isn't here...it doesn't exist.  (+ info)

Can adrenal insufficiency cause high blood pressure also?

I was reading that adrenal insufficiency can cause low blood pressure. but it makes sense to me that it could do just the opposite too! correct?
I have heard of charged water, but given in a different way by readings of Edgar Cayce. Thanks so much for your information.

Primary adrenal insufficiency, also known as Addison's disease, occurs when the adrenal glands cannot produce an adequate amount of hormones despite a normal or increased ACTH (adrenocorticotropin hormone) level. Most patients with Addison's disease experience fatigue, generalized weakness, loss of appetite, weight loss and low blood pressure with lightheadedness after standing or sitting up.

Treatment of adrenal insufficiency involves the administration of adrenal hormones to mimic the normal output by the adrenal glands.
Underactivity of the adrenal glands is called hypoadrenalism. Many of the symptoms of hypoadrenalism are due to a deficiency of the steroid hormone cortisol, which is a potentially fatal deficiency if left uncorrected.

Other corticosteroids may be used to treat hypoadrenalism, including cortisone acetate, prednisolone (eg Deltacortril) and dexamethasone. However, it is difficult to judge the correct dose of prednisolone and dexamethasone. This may lead to the complications of long-term steroid treatment including avascular hip necrosis, osteoporosis, worsening of diabetes mellitus and HYPERTENSION(high blood pressure).
Cortisone acetate must be converted by the body into an active steroid, and the efficiency of conversion may vary between patients.

You should talk to your doctor for more details.
Take care as always!  (+ 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?


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)

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)

What functions do the cardiovascular system and respiratory system have in common?

Why is it advantageous for the cardiovascular and respiratory systems to be connected and interrelated?

they are both responsible for delivery of oxygen to the body.  (+ info)

What does nonmotile sperm with cytoskeleton defect have to do with respiratory disease/infections?

Patient has a hereditary form of a male sterility involving nonmotile sperm. His condition is traced to defects in the cytoskeleton components of the sperm's flagella. Based on these findings, the physician suspects that Kevin also has a long history of recurrent respiratory tract disease. Kevin confirms that he has had colds, bronchitis, and influenza more frequently than his friends. Why would the physician suspect that Kevin probably had a history of frequent respiratory disease based on his diagnosis of sterility due to nonmotile sperm?

I suspect that you are "testing" the yahoo answers audience rather than asking a real question. In any case, I would guess that Kevin suffers from Kartegener's syndrome, or primary ciliary dyskinesia.

Although there are familial forms, patients with Kartegener's syndrome can have a variety of mutations that affect the functioning of their cilia.

Cilia are microscopic whip-like structures that are found in various parts of the body. They have a variety of functions including facilititating cellular movement, emrbryonic developement, clearing secretions, etc.

A genetic defect that impairs the function of these cilia will clinically manifest itself whereever these cilia are found.

The whip-like tail of the spem is actually the cilia of the sperm. Our respiratory passages are lined with cilia to constantly move secretion up the respiratory pathway so that we may cough these secretions out.

Cystic fibrosis is also a good answer, is more commonly encountered, and thus would probably be more likely in this patient; however, the question specifically states the patient has a "hereditary form of a male sterility," which suggests that the chief complaint in this case is sterility rather than chronic cough and sinusitis.  (+ info)

how does the nervous system work with the respiratory system? How do they work together?

Does the respiratory system and the nervous system actually work together?

The nervous system effects every single part of your body. The nervous system consists of every nerve tissue in the body. You have nerve tissue in your fingers to tell you when something is hot or cold, in your stomach to let the brain know to send the impulses that digest food, and in your lungs to tell you when to breathe and how much air to breathe in. There are 3 respiratory centers in the brain that control the respiratory rate.

There are stretch receptors in the lungs that tell the brain that the alveoli are completely expanded and that it is time to stop breathing. Your breathing also controls the acidity of the blood. If the blood gets too acidic, the brain tells you to breathe faster to release carbon dioxide. There are also receptors that tell you when to cough, sneeze, sigh (breathe in deeper), etc.

In addition to all of that, you have smooth muscle (involntary muscle) lining the respiratory tract. The nervous system tells the smooth muscle when to contract and when to dialate in response to various stimulation. There are many, many, many stimuli that cause responses - far too many to go over here.  (+ info)
