Lungs

If you have Internet access you should utilize all of the databases available from your library's website. the journal articles you get will be shorter than a book and probably more up to date. you can call and ask to talk to the librarian and they'll walk you through the steps of how to use the databases. Also, check to see if you library does 24/7 reference via chat (will be advertised on the website) and even better, if they have a service called Live Homework Help then even better -- LHH will hook you up with a tutor and the tutor will help you get your homework done, again all from the comfort of your home!

There are several ways to answer this question; I'll tackle two: the embryologic answer and the teleologic one. Embryologically (ie, during development), the lungs develop as an outpouching of the foregut, the first part of the gastrointestinal tract that runs straight through the center of the body. As the lung bud grows and descends from its origin in the foregut, it begins to divide multiple times. The first division forms the primary bronchi, the next division forms secondary bronchi, etc. Successive divisions of bronchi make smaller bronchi and bronchioles, until ultimately division ends with the air sacs (called alveoli). It's because of all these divisions of the lung bud that we have so many alveoli. A teleologic answer gets to the bottom of why it's important to have so many alveoli. The short answer is that for the lung to to its job of exchanging oxygen and carbon dioxide gases, it needs to have a large area of contact with air from the environment. Having many alveoli results in a large surface area for gas exchange.

The same way as other animals with "lungs".

Air is taken into the body and gaseous exchange occurs with the red blood cells.

The "lungs" of a lungfish are much simpler in structure than those of a mammal. They are just simple sacs, rather then the spongelike structures of mammal lungs. The general way they work is the same as a mammal's lungs, but they are not as efficient, having a smaller surface area.

They allow oxygen from the air we breath to enter the blood, and they allow carbon dioxide from the blood to leave the body. This occurs in a well controlled manner in health.
The main function of your lungs is to provide oxygen to other parts of your body by loading it into red blood cells and sending them to that part of the body. Axle718
The function of the lungs is to add oxygen to the blood to be pumped through the body

No

ribs and bones

The survival rate at one year after transplant was 77% for lung transplants and 64% for heart-lung transplants

Extraintestinal amebiasis accounts for approximately 10% of all reported amebiasis cases.The most common form of extraintestinal amebiasis is amebic abscess of the liver.Other forms.include infections of the lungs, chest cavity, brain, or genitals.

well the right lung has 3 lobes and the left lung has only 2. its to give room for your heart.

Mantle cavity

It depends on how hurt you are. Bronchial pneumonia or pulmonary pneumonia can hurt you a lot. But there are other things like bronchitis, bronchial asthma, emphysema, lung cancer and tuberculosis. You have to consult your doctor.

Bronchi, Bronchioles and Alveoli.

Bronchi and Bronchioles

- transport systems

Alveoli

- Respiration occurs

No, bronchioles branch of a bronchus.

The term "stoic" describes an emotional state (resignation) rather than an acid, but aside from that, you could definitely damage your lungs by inhaling acid. As a general rule, the only thing you should be inhaling is air. That is all your lungs are designed to inhale.

If you are vomiting it does. But usually food doesn't go back into the esophagus because it tends to go down hill, going back into the esophagus is going against gravity.

Also, the lower esophageal sphincter normally prevents stomach contents from flowing backwards. Sphincters are rings of muscle that open and close to control the flow in various places in the body.

A spot on the lung tissue can be caused by scarring or from a benign tumor. It can, but does not always mean lung cancer. Asking your physician is the best course of action.

Once they actually fail, the person will die immediately. You cannot live without working lungs.

during the inhalation of air to the lungs. it goes through your nose, which has hairs that trap the dust and other particles. from there if the irritants are still in your body system they will be stuck to the mucus in your pharynx and trachea.

the body releases these irritants by a sneeze, or a cough.

but if the irritants can get past the first two defenses, the white blood cells in your lungs can attack those irritants.

Pneumorrhaphy is suture of the lung.

When a person inhales helium from a balloon or other inflated object, he is cutting off his access to oxygen. In this way, the person is actually suffocating himself on a cellular level. He is inhaling "air", but because there is no oxygen his body is becoming starved for it and cannot function as it should. If a person was to inhale helium for long enough, he could pass out and if oxygen was not promptly provided to him, he could suffocate and die.
Helium alone is very dangerous because it can cause your body to become deoxygenated quite rapidly, which will result in you suffocating and dying within a matter minutes. Helium can easily replace oxygen in your system, and thus can kill you quite quickly as a result. It's basically the same as holding your breath underwater until you drown, only the pain isn't as intense because helium is already in your lungs.

The lungs also produce liquid that becomes part of the amniotic fluid

fart alot......

Frogs are amphibians. Meaning that they have an aquatic early stage (e.g. Tadpole). A tadpole relies mainly on gills to breath, until it undergoes metamorphosis, loses its gills, and gains lungs. Adult frogs rely mainly on lungs to breathe air, and are also able to breathe through their skin both above water and underwater.

due to regularly smoke there should be the lungs cancer and others like t.b,istama and many more you know all that,the cigrate is made up of nicotine and tobacco that is very much harmful for human circulatory system

In aging there is usually a gradual INCREASE in the compliance of the lung tissue (i.e. a decrease in tissue elasticity). This means that the lung is more easily distended but then has more difficulty in recoiling to it's original state and so exhalation can become difficult. The compliance of the chest wall is decreased in aging, and respiratory muscles weaken, adding to this effect.
