Do your lungs fill with water when you drown?
No, your lungs do not completely fill with water when you drown. Yes, some water enter the lungs, but once your lungs receive an over abundance of liquid your throat and chest passage ways will seize up and seal themselves off to prevent them being filled.
When you drown the reason for death is not from your lungs being filled with water but rather asphyxiation brought on by your own body trying to keep from filling with water.
When someone is under the water for a brief period and someone performs CPR to resuscitate them, the person performing CPR is trying to force air into the victim's seized off lung cavities. This is why the victim will only spit up a small bit of water after being rescued from drowning and gasp for air. A person with a lung full with water would not have the ability to gasp.
If someone's lungs were to fill with water, there would not even be a point in trying to resuscitate them since that kind of damage would be irreversible.
What tude does air travel through to get to your lungs?
Nose or mouth
The nose is the best route for air to get into the lungs, as it is a better filter than the mouth. The nose decreases the amount of irritants that reach the lungs, whilst also heating and adding moisture to the air.
Mouth breathing is usually needed when exercising or when more air is needed, because the nose is not the most efficient way of getting large amounts of air into the lungs.
Journey down the windpipe
After entering the nose or mouth, air travels down the trachea or "windpipe". The trachea is the tube lying closest to the neck.
Behind the trachea is the oesophagus or "food tube". Air moves down the trachea when we inhale and food moves down the oesophagus when we eat.
The path air and food take is controlled by the epiglottis, a gate that prevents food from entering the trachea. Occasionally, food or liquid may enter the trachea, resulting in choking and coughing spasms.
Route into the lungs
The trachea divides into one left and one right breathing tube, termed bronchi. The left bronchus leads to the left lung and the right bronchus leads to the right lung. These breathing tubes continue to divide into smaller tubes called bronchioles.
The end of the trip
The bronchioles end in tiny air sacs called alveoli. Alveoli, which means "bunch of grapes" in Italian, look like clusters of grapes attached to tiny breathing tubes. There are over 300 million alveoli in normal lungs. If the alveoli were opened and laid out flat, they would cover the area of a doubles tennis court. Not all alveoli are in use at one time, so the lung has many to spare in the event of damage from disease, infection or surgery.
What will happen to your lungs if you take drugs?
Nothing will happen. But if you are a drug addict, it may damage your kidneys and some drugs cause burning kind of pain in your stomach..
So we should not depend more on drugs especially the antibiotics.
How many lobes do the right and left lung have?
The right lung contains three lobes. The left lobe only has two. Because of the heart on the left side, the left lung only has two lobes to make more room for the heart to pump on that side.
What does blood from all parts of the body except the lungs go to of the heart?
The left ventricle is responsible for the movement of blood into the aorta, which carries it to all areas of the body except for the lungs. The blood passes through the lungs through the pulmonary trunk which originates in the right ventricle.
Where the air goes through from out to your lungs?
It goes into small alveoles, and then into the blood stream. It will then go to the heart that will push the oxygen into the rest of the body trough the aorta and arteries.
What changes occur as the conducting tubes of the lungs become smaller?
Cartilage rings are gradually replaced by regular plates of cartilage!
How do the lungs work with other organ systems to keep the body healthy?
The lungs are part of the respiratory system, the main function of which is to provide oxygen for the body and release carbon dioxide from the body.
The first step in providing oxygen is inhalation. When a person inhales, the air goes through his nose/mouth, down his trachea, and into tiny air sacs called alveoli. These alveoli are covered in blood vessels, and it is here where the gas exchange takes place. Oxygen diffuses out of the alveoli into the capillaries. It is then carried by the blood into the heart and then throughout the entire body.
Releasing carbon dioxide from the body is basically the reverse process. In the body, carbon dioxide is created as a waste product that must be exhaled. So the blood carries carbon dioxide from tissues to the heart and into the lungs. The gas exchange occurs in the alveoli and the carbon dioxide is exhaled.
Of course in real life, this occurs almost simultaneously. Breathe in, breathe out, breathe in, breathe out, breathe in...
Hope this helps!
The loss of elasticity in the tissues of the lungs is called what?
The loss of elasticity of the alveoli is caused by high pressure in the bladder causing an unsafe drop in blood pressure which will cause alveoli to lose their elasticity. It can also be caused by being overweight, underweight, or eating feces.
Does the trachea connect the mouth and nose to the lungs?
This tube is technically called the trachea, but is commonly referred to as one's windpipe. Be careful not to confuse it with your esophagus, which connects your mouth to your stomach in the digestive system.
They are kept clean by the little hairs inside your lungs that brush away all the dirt from your lungs, if you would like more answers to any questions that you may have that you need answering wether they are from how to cook a zebra to what how many geometictoric tonnes are in the earth?
The diaphragm is a strong wall of muscle on the bottom of the chest cavity. As this wall of muscle expands downward, a vacuum is created which pulls air into the lungs. As the diaphragm returns to it's original position, air is pushed out of the lungs.
What would happen to the body if the lungs shut down?
Oxygen can no longer enter the bloodstream, which in turn will cause the brain to begin shutting down. If the brain is only deprived for a short time (3-5 minutes,) minor brain damage may occur, but any longer than that can have severe to deadly consequences. The brain cells will die off and cannot be restored.
What is The membrane attached to the lung called?
lungs, elastic organs used for breathing in vertebrate animals, excluding most fish, which use gills, and a few amphibian species that respire through the skin. The word is sometimes applied to the respiratory apparatus of lower animals.
The human lungs are paired organs, located on either side of the heart and occupying a large portion of the chest cavity from the collarbone to the diaphragm. Air enters the body through a series of passages, beginning with the nose or mouth. It travels to the chest cavity through the trachea, which divides into two bronchi, each of which enters a lung. The bronchi divide and subdivide into a network of countless tubules. The smallest tubules, or bronchioles, enter cup-shaped air sacs known as alveoli, which number about 700 million in both lungs. Each alveolus is surrounded by a net of capillaries. As blood flows through these vessels, carbon dioxide passes into the alveoli, and oxygen diffuses into the bloodstream. The capillaries are part of a vast network of pulmonary blood vessels that connect the lungs directly to the heart via the large pulmonary arteries and veins. The alveoli are clustered in groups, or lobules, and the lobules are clustered into lobes.
In humans, the left lung has two lobes; the right lung three. The lungs are covered by a thin membrane called the pleura.They are expanded and contracted (thereby inhaling and exhaling air) by the combined movement of the diaphragm and the rib cage, which is alternately raised (expansion) and lowered (contraction) by the chest muscles. In recent years, smoking has been found to cause severe and sometimes fatal diseases of the lung, such as cancer and emphysema. Pneumonia is an inflammation of the lung tissue caused by various agents or organisms such as viruses. Asthma, a hypersensitivity or allergic response to some stimuli, covers a range of severity and is characterized by bronchial spasms and difficult breathing.

THE ANSWER IS A DEFINITE YES, YES AND YES. ADULTS MISTAKE IT FOR OTHER ILLNESSES. I had no idea what Bronchialitis/Bronchiolitis was until I ended up in hospital and was told that I had Sinisitus. The medication they gave me stopped a migrain type headache and opened the door to the real problems, the day after my chest closed and I could not breathe well. I then decided to visit my homeopath, thinking this sinus is out of hand. Boy was I wrong, it wasn't Sinusitus. He did a blood test and told me that I had Bronciolitis/Bronchialitis. Which he then gave me medication which consists of drops and tabs every hourly for a day then 3 hourly for 3 days. And told me to complete the course which is for a month and to stay out of the windy weather as it is most dangerous. But although my chest has opened somewhat this is when you feel worse than ever as you still have pain breathing, but also a constant burning sensation which feels like you are permanently having some sort of heart attack and you are feverish. You hurt all over and especially chest and neck area, and are extremely weak as this illness drains your energy completely. Slowly you start coughing and if there is any phlegm you need to spit it out. You need to stay out of contact of people as it is highly contagious. If you have a humidfier use it. If not boil a hot cup/pot of water and throw a towel over your head and inhale the steam. This quickly realeases phlegm and helps heal the Bronchial passage. All I can say is stay hydrated and good luck as I am still going through this, I am on day six.
Can a human live with one lung?
Yes u can live without a lung because the lung is like a ballon so u will only run out of breth easier than normal!!!
What do the mucous and cilia do in the trachea and bronchi?
The bronchus in the lungs are lined with hair-like projections called cilia that move microbes and debris up and out of the airways. Scattered throughout the cilia are goblet cells that secrete mucus which helps protect the lining of the bronchus and trap microorganisms.
The purpose of mucus is to lubricate and protect the organs that it lines. Mucus is supposed to be thin, clear, and watery. Cloudy, yellow, or green mucus are signs of an infection.
What is the prognosis for patients who have cancer?
Leukemia is one of the forms of Cancer that is experiencing some amazing breakthroughs. Your chances of recovery depend greatly on your health and other conditions that can't be plugged in to a mathematical formula. Your doctor or local Cancer Society would be a far better resource for that information.
AnswerIt would depend entirely on the type of leukemia. While some forms are easily remissed, others are not. This would be a question for your oncologist. AnswerThe first poster is correct. I suggest that you go onto: www.google.comType in: Leukemia chatlines.
The reason I suggest this is you can chat with other people in the same situation as yourself and lessen the stress for you. It also gives you the opportunity to find out what new and improved methods that other people with Leukemia are receiving.
Good luck & God Bless
Leukemia is a broad name for some 88 blood diseases. Any disease of the blood or bone marrow is considered Leukemia. Many, many new treatments are extremely promising and successful in many cases. I have leukemia. I have been in treatment for almost 2 years. I am progressing very well.
Three ways in which the lungs are adapted for gas exchange?
Many alveoli-increases surface area for gas exchange
Thin alveolar wall-allows gases to diffuse easily and fast
Thin capillary wall-easy diffusion
Inner wall of alveoli-allows gases to dissolve, which they need to enter the capillary
