Lungs

This is called a Pulmonary Edema. Everybody has a small layer of fluid on their lungs, but this is where the air sacs within become logged with water and it then becomes dangerous and develops into this condition. The symptoms include breathing difficulties, coughing and distress.

Actually it is the caffeine in coffee that helps to improve the airway function of an asthmatic. Medical researchers found that the body cannot distinquish between caffeine and Theophylline, a drug commonly prescribed for persons with asthma. However, they caution one should never use caffeine instead of their prescribed medication. Two six-ounce cups of coffee, soda (colas) or tea or two chocolate bars contain enough caffeine to help alleviate asthma symptoms in an emergency situation. Coffee is a weak bronchodilator, and chemically related to the drug theophylline. It's been known for well over 100 years that a few cups of coffee can help during an asthma attack. If you are having severe attacks I would consult your doctor and only follow your doctors care when concerning care for your asthma.

There are a number of places in the body where the pressures are lower than atmospheric, or negative. For example,

1- When we breathe in (inspire) the pressure in the lungs must be lower than atmospheric pressure. The lung pressure during inspiration is a few centimeters of water negative.

Yes! Inhaling nystatin clears nasal congestion and postnasal drip.

about 10 years ;c ) The worst effects pass after 24-48 hours.

Then it takes ages.

But it is worth it. after a week you (I did) notice health gains.

If I could feel better after a week, imagine how much better you feel after a year....

i don't really know, but i will pray for those who do have lung cancer.

There is a higher rate of cures and longer remissions than there used to be; some survivors are 10+ years! I'm a survivor of almost 2 years and hope I last at least that long!

The trachea or windpipe divides into the two primary bronchi which enter each lung. These further divide and subdivide into smaller and smaller bronchi finally forming tiny tubes called bronchioles that end in alveoli (air sacs that facilitate oxygen transfer from the lungs into the pulmonary capillaries).

Technically yes. However, there are a few more strucutres that thanks to their histological properties can participate in the gas exchange process: respiratory bronchioles, and alveolar ducts.

The most immediate effect would be an increase in heart rate. In addition, regulation of heart rate, contractile state, and conduction of electrical impulses through the heart would be impaired.

The reason for the observed effects are that the vagus nerve carries important information to the heart from a part of the central nervous system called the parasympathetic nervous system. The parasympathetic nervous system is often considered the "rest and digest" system. It decreases heart rate, decreases how strongly the heart contracts with each beat, and decreases the rate at which electrical impulses are conducted through the heart. This is in contrast to the effects of the sympathetic nervous system on the heart; the sympathetic nervous system raises heart rate, force of contraction, and rate of electrical conduction in the heart.

A normal heart does not require information from the parasympathetic and sympathetic nervous systems in order to beat. The heart has an intrinsic pacemaker that allows it to generate heart beats on its own. The heart's pacemaker generates a pace at a rate of about 100 cycles per second, which means that if the heart was to take matters into its own hands (ie, have no innervation), then it would beat at about 100 beats per minute (bpm).

If that's the case, then why do normal adult hearts beat around 70 beats per minute and not 100?

As was hinted at above, normal hearts are innervated by the parasympathetic and sympathetic nervous systems. And both act on the heart at the same time. While you might think that the systems would cancel each other out, it turns out that the heart receives more sympathetic stimulation than parasympathetic stimulation at rest. The result is that the heart is effectively told to reduce the heart rate from the normal 100 bpm to something closer to 70 bpm.

Thus if you take a normal heart at rest that's innervated by both sympathetic and parasympathetic systems, and then sever the vagus nerve, you lose the parasympathetic input to the heart, while leaving the sympathetic input intact. The result is that the resting heart rate increases, to something closer to 100 bpm. ________________________________________________________________________ Cutting the vagus nerve would increase the heart rate. At REST there is more Parasympathetic input to the heart because it slows the heart rate. However during activity there is more sympathetic imput than parasympathetic imput. If all nerves were cut from the heart it would continue to beat in a Ryhmic way because of the electrical system, as demonstrated in heart transplants.

The systemic circulation brings oxygen-filled blood to the body tissues, and returns carbon-dioxide filled blood to the heart. The pulmonary circulation brings carbon-dioxide filled blood to the lungs.

no, because asthma is a disorder in the airways, not the lungs in the first place. when triggered by an irritant, what happens is your windpipe narrows down, and mucus clogs it, causing breathing difficulties, and then an asthma attack. asthma has nothing to do with the lungs - they will still be perfectly normal.

Alveolar means pertaining the the alveolus (plural alveoli), the small air sacs in the lungs.

smoke has carbon dioxide

your body can only take a certain amount of co2

we breathe in oxygen when too much carbon dioxide go into the system it cooks the lungs turning the lung black whereby you will have problems breathing

bronchospy

Blood Clots in the veins of Legs is a medical condition better known as DVT or Deep Venous Thrombosis. It is potentially life threatening condition and needs treatment --the sooner the better. There are a number of predisposing factors which may lead to DVT-- trauma, History of Surgery, prolonged immobilization, oral contraceptive pill intake in women > 35 years who are also smokers, long travel history, malignancy, clotting disorder etc. The blood clot may migrate to the lungs and cause a life threatening condition known as PE or pulmonary embolism manifested by sudden onset of shortness of breath, chest pain. Hence once a person is diagnosed with DVT, immediate treatment with anti coagulants are initiated by the physician.

There are two lungs simply called the left and right lungs. These large structures take up most of the Thoracic Cavity which changes tize in order to pull air in or push it out of the lung. The right lung has three Lobes (parts that sit on top of each other) While the left lung has only 2. This is because the left ventricle of the heart sits over to the left and takes up some of the space the left lung would otherwise inhabit. The left lung has a curved gap for the heart called the Cardiac Notch.
because the heart is there

bronchi (singular bronchus)

--Allison

your lungs silly through your mouth and nose. unless you are talking about gas and that is a chemical reaction inside your body and that's a different kind of air. or an accidental needle air bubble can be put in the vien but that kills you

the diaphragm is a muscle located below the lungs. When the muscle tissue of the diaphragm contracts, it moves down, creating a vacuum inside the lungs, and pulling air into them. To breathe out, the diaphragm simply relaxes, springs back up, and the air is expelled. Not all of the air ever comes out of the lungs during an exhale.

Smoking can seiously damage your health and people around you. You can get cancer and die also befor that you will get yellow teeth smell horrible and your lungs will start to get black tar on them which makes it harder for you to breeth so please please stop smoking iit can kill you!!!!!!!
