What is the relationship between respiration and the respiratory system?
, which generates ATP in your cells, requires
oxygen
to take place, also, it generates CO2 as a waste product.
The respiratory system allows oxygen to diffuse into your blood, and
carbon dioxide
to diffuse out. The blood then carries the oxygen to the cells, so cellular respiration to continue. When the blood reaches the cells, it also takes the carbon dioxide out of the cells, and carries it to the lungs to get rid of it.
Does vasoconstriction conserve heat?
Yes, Vasoconstriction is the constricting (narrowing) of the arterioles supplying the the blood to capillaries close the skin surface. Heat is lost from the blood that does pass close to the surface (via radiation).
Vasocontriction however, allows much of the blood to pass below the fatty adipose tissue rather than close to the surface.
Vasodilation is the dilation (enlargening) of the arteriole that supplies blood to the capillaries. Therefore less blood flows beneath the adipose tissue, and much more flows close the skins surface. Much more heat is lost via radiation this way.
Vasoconstriction is co-ordinated via the sympathetic nervous system (stimulates effectors like the smooth muscle)
Vasodilation is co-ordinated via the parasympathetic nervous system (inhibits effectors like the smooth muscle)
What is the circulation of blood to and from the lungs known as?
The flow of blood to and from the lungs is called pulmonary circulation.
I am no medical expert, but since your blood is not pumping when you are dead, then I believe the answer is no.
What does the word biapical mean?
Bi means two, and apical refers to an apex, so typically this term would refer to the two apices (top pointed part) of the lungs. For example, there may be biapical scarring in the lungs from an old TB infection.
An individual's susceptibility to certain diseases or conditions can be affected by:
- genetics
- immediate family medical history
- personal medical history
- personal lifestyle
- personal or community environment
- personal dietary habits
- smoking
- use of tobacco products
- exposure to chemicals or carcinogens
Is pulmonary fibrosis contagious?
"Fibrosis" is a term used to refer to scarring, so pulmonary fibrosis means scarring in the lungs. No it is not contagious. Little is known about the mechanism of the disease, but there does seem to be a genetic component and some sort of trigger - either environmental, lung injury, etc. The body actually attacks itself (autoimmune disorder) and destroys its own lung tissue.
What does it mean if you have a sore throat with blood in it when you cough?
There are too many diagnoses that can cause those symptoms to guess which may be causing these. It will take an examination and maybe some diagnostic tests to know for sure. It can be a serious sign when there is blood from a cough, so don't hesitate to have an examination to find out.
What happens in pulmonary edema?
Normally very little to no fluid enters the alveoli of the lungs. In pulmonary edema there is increased pressure in the pulmonary veins. So fluid escapes in the alveoli of the lungs, making transfer of the oxygen impossible from such alveoli. Patient feels suffocated and starve for oxygen, in pulmonary edema.
What food should be given to children with primary complex?
Children with Primary Complex also known as TB should be given healthy meals. The children need to eat fish, vegetables, fruit, brown bread, and eggs.
Would death from a pulmonary embolism be quick?
According to several sites I've been reading, as I recently lost someone due to this, is that in most cases, it is quite quick.
What kinds of medical conditions may result in a collapsed lung?
All of these can cause it: cystic fibrosis, asthma, COPD, lung cancer..an infection in the lungs can also cause a collapsed lung. And, of course, trauma.
How much electricity does a cpap machine use?
After using the CPAP from Feb. to August, my electricity bill has also been refigured for Jan.-June. I am on a budget payment plan and the payment has increased from $76 to $115! I live in a one bedroom condo. How can this be? It is the CPAP running all night (with water canister) which is the new electric addition. Do others have these big increases in electric bills? Is there a way to eliminate this cost? Why aren't we told of this huge cost before we agree to it?
Is pulmonary edema contagious?
Pleurisy affects the membranes that line the chest cavity and around the lungs. These 2 layers of membranes are separated by a thin layer of fluid that allows them to move smoothly by one another with each breath. If the membranes swell, they rub against each another, causing sharp pain when breathing and/or coughing. This symptom/condition is called pleuritis or pleurisy. Usually, there is no pain between breaths. More symptoms may involve shortness of breath, dry cough, or fever/chills.
Pleurisy is not a disease by itself--it is a symptom of another condition, such as viral infection, bacterial infection (i.e. pneumonia or tuberculosis), or an auto-immune condition (like lupus or rheumatoid arthritis). As such, pleurisy is not contagious, BUT some of its possible underlying conditions, such as tuberculosis, can be VERY contagious, especially to young children and people with low- or non-functioning immune systems (from AIDS, MDS [not muscular dystrophy, but myo-dysplastic syndrome], Leukemia, etc.).
In addition to being caused by sickness, pleurisy can also show up after a chest injury or heart surgery. Occassionally its cause is undetermined. To try to diagnose the underlying cause, physicians may listen to the lungs with a stethoscope, look at an X-ray, run blood tests, and/or remove a fluid sample from the chest with a needle.
The symptoms of pleurisy can be diminished by treating the underlying cause. Bacterial infections can be treated with antibiotics, non-steroidal anti-inflammatory drugs can be used to help symptoms in the case of viral infections, which are usually left to run their course. Codeine can be used to diminish coughing and pain.
As a possible complication of many illnesses, pleurisy can be chronic or reoccur, with different levels of severity. Persons with severe chest pain that goes away when they hold their breath, or go along with a fever, may want to see their doctor to diagnose possible pleurisy and any other issues at hand.
How bad is the number 74 on an oxymeter?
A pulse oximeter is a device that measures the percentage of oxygen in the arterial hemoglobin. The normal range of oxygen saturation (o2sat) is 95%-100%. A low o2sat can lead to hypoxemia (decreased oxygen in the blood)
Recent sleeping oxygen saturation level was 81 Is this normal what can cause this?
Normal oxygen saturation levels vary slightly depending on age and activity. A blood oxygen level of less than 90 percent is considered abnormal. The organs in the body need a continuous supply of oxygen to function properly. If oxygen saturation levels in the body become too low, various problems can develop. When oxygen saturation is too low it is called Hypoxemia.
What is the lethal level of co2 in blood?
OSHA's maximum safe level is 3% (30,000 ppm); lethal concentration (death in 30 minutes) is 10% (100,000 ppm)

What causes involuntary sharp intake of breath?
An emotional shock or pain can cause a sharp intake of breath.
What is the rattle in your chest when you cough?
You should really go to the doctor it could be neumona I would go get that checked out
Use of accessory muscles in emphysema?
The accessory muscles of respiration are the sternocleidomastoid, scalenes, serratus anterior, pectoralis major and minor, upper trapezius, latissimus dorsi, erector spinae (thoracic), iliocostalis lumborum, quadratus lumborum, serratus posterior superior and inferior, levatores costarum, transversus thoracis, and subclavius.
The diaphragm is the main muscle of respiration (normal/relaxed breathing), assisted by the intercostals. No accessory muscles should be recruited during normal respiration unless there is a respiratory disorder. During quiet inspiration, the diaphragm and intercostals are activated. During quiet expiration, the inspiratory muscles relax and the elastic recoil of the lung tissue combined with intrathoracic pressure causes air to be pushed out of the lungs. There is little or no respiratory activity of the abdominals.
When increased oxygen is required during physical activity e.g. when running, accessory muscles will activate to assist forced respiration.

What is Wegener's granulomatosis?
Wegener's granulomatosis is a rare disease of uncertain cause. It is characterized by inflammation in a variety of tissues, including blood vessels (vasculitis). Inflammation damages vital organs of the body.
Wegener's granulomatosis primarily affects the upper respiratory tract [sinuses, nose, trachea (upper air tube)], lungs, and kidneys. Other organ systems that can be affected by the disease include the nervous system, ears, eyes, heart, and skin.
What are the symptoms?
The symptoms of Wegener's granulomatosis and their severity vary among patients. General signs of the disease may include:
- Loss of appetite
- Weight loss
- Fever
- Fatigue
Most patients first notice symptoms in the respiratory tract. Symptoms may include:
- Persistent runny nose (also called rhinorrhea) or the formation of nasal crusts and sores
- Nasal or facial pain
- Nose bleeds or unusual nasal discharge, caused by inflammation of the nose or sinuses
- Cough that might include bloody phlegm caused by upper airway or lower airway (lung) inflammation
- Chest discomfort
- Middle ear inflammation (also called otitis media), pain, or hearing loss
- Voice change, wheezing, or shortness of breath caused by inflammation of the trachea
Other possible symptoms include:
- Eye inflammation
- Joint pain (arthritis) or muscle pain
- Rashes or skin sores
- Kidney inflammation*
*Although kidney inflammation is common, it is not usually associated with symptoms, such as pain.
How is it diagnosed?
Wegener's granulomatosis has symptoms similar to a number of other disorders, which may make it difficult to diagnose. However, for the most effective and successful treatment, early diagnosis is critical.
It is the combination of symptoms, results of physical examinations, laboratory tests, X-rays, and sometimes a biopsy (sample) of affected tissue (skin, nose, sinus, lung, or kidney) that together prove the diagnosis of Wegener's granulomatosis. Following treatment, these factors are also critical in judging whether the disease is active or in remission.
A positive blood test for antineutrophil cytoplasmic antibodies (ANCA) can support a suspected diagnosis of the disease. However, this blood test does not by itself prove the diagnosis of Wegener's granulomatosis or determine disease activity.
Other tests that influence a doctor's judgment of disease activity include:
- Measures of anemia (red blood cell count)
- Sedimentation rate (the speed in which blood cells settle in a vertical glass tube) Urinalysis
- Chest or sinus X-rays
Sometimes the lungs may become abnormal even though there are no symptoms such as cough or shortness of breath. Therefore, it is important to periodically have lung X-rays if you are diagnosed with Wegener's granulomatosis - even if you don't have any symptoms of lung disease.
What causes pulmonary artery dilation?
Each artery in the human body has a baro-receptor. These baroreceptors, when innervated, cause dilation and constriction of the artery. For instance, if someone is losing a vast amount of blood, the baro-receptor notices a decrease in volume and sends an impulse to the brain which changes the amount of hormone released from the pituitary gland. The hormones are known as prostaglandins and have been pharmacologically refined to assist with the dilation in the pulmonary vessels. You may know this drug to be Viagra.
Dark earwax is just earwax that has been in your ears for a very long time. It doesn't mean that there is anything wrong with you, but if you are experiencing any discomfort or hearing loss you should see your physician immediately. Otherwise you can just use some of the over the counter medications or such to break up or soften the old earwax & make it easier to remove.
Does green phlegm mean there is a bacterial or viral infection?
It's actually a good sign, believe it or not. On the one hand, it signifies that you have an infection (usually of the lower respiratory tract), but the colour also suggests that your body is at work fighting the infection. If your body hasn't defeated the infection in five to seven days, then you should see your doctor, who will prescribe antibiotics. However, it is always preferable to let your body kill the germs for you, since overuse of antibiotics can lead to antibiotic resistance in many infections.
