Lungs
Lungs are a pair of elastic and spongy organs that help the body breathe. They are present inside the rib cage in thoracic cavity of humans.

Is the heart and lungs and veins connected?
Of course Dummies, How can you breathe if they weren't connected?
Possibly this is know as 'congestive heart failurs'.
How are dust and foreign particles removed from the lungs?
Air that is breathed in goes past moist tissues and moist hairs. The dust and other foreign particles stick to the moist tissues and moist hairs. Breathing through the mouth filters out fewer foreign particles, so is less good for the lungs.
Tiny hairs in the nose called cilia and mucus trap the dust and other particles and either push them back out the nostril or down into the digestive system.
Mucus and something else
mucous covered membranes and microscopic hairs called cilia sweep dust away, then sneezing and coughing will expel it from the body or it will be swallowed
Weirdly enough, your nostril hairs stop dust from traveling into your lungs.
It dose reach the lungs but a sneeze or a cough brings it right up
By the goblet cells and cilia in your windpipe. Smoking kills these cells, which is when smokers get ill.
ciliated mucous lining in the nose
Goblet and Ciiated cells
How the respiratory system is link to the circulatory system?
the circulatory and respiratory system are linked because when the heart gets oxegyn from the lungs, the arteries in the left of right atrium of the heart take that blood and give it to all the other cells in your body, pick up carbon dioxide as they go along, and that what you breathe out, then when you breathe in, the same cycle repeats over again
Oxygen moves from the lungs into blood through the walls of what?
That would be the heart. The pulmonary vein carries oxygenated blood from the lungs to the heart's left ventricle, it then travels through the left atrium and out the aorta into the arteries and then the arterioles. It then enters the capillaries, here the oxygen diffuses into the cells of the body, and carbon dioxide diffused into the capillaries and bloodstream. The blood then continues to the veinoles, veins and back into the heart through the inferior or superior vena cava, into the right ventricle, right atrium and out through the pulmonary artery to collect oxygen from the lungs again. So starting from the beginning, the diagram of blood flow is as follows:
Lungs - pulmonary vein - left ventricle - left atrium - aorta - arteries - arterioles - capillaries - veinoles - veins - superior/inferior vena cava - right ventricle - right atrium - pulmonary artery. And the cycle continues :)
Describe the pleural coverings of the lung and explain their purpose?
Each lung is suspended in its own pleural cavity and rests on the muscular diaphragm. The medial surface has a hilus (indentation) where the bronchi enter. Because of the shape and location of the heart, the lungs differ in size and shape. The left lung is smaller with 2 lobes, the right has 3 lobes. Lungs are mostly air spaces and connective tissue. The lung contains the air sacs where oxygen diffuses from air sacs into the blood vessels and waste carbon dioxide diffuses from the blood vessels into the air sacs. Each lung exists in a pleural cavity, a serous membrane compartment which prevents friction damage as the lungs expand and contract during breathing. The visceral pleura is the membrane fused to the outer surface of the lung; the parietal pleura is the membrane which lines the body wall. Between the two membranes in the pleural fluid.

Does Wagner's disease effect the lungs?
wagoner's disease affects the lungs, however, Wagner's disease is entirely different and happens to be a disease of the eye.
how does it affect the lungs and how serious is it when it does
How do smokers clear their lungs of mucus?
because the smoke from the cigarette slowly burn away the Cecilia( hair like fibers) that sweep mucus and other dust like material out of the lungs, so once they are burnt away it can no longer sweep out the material which causes you to produce the so called smokers cough to ex spell all of the materials. deandre233@yahoo.com
Do white people have bigger lungs?
white people come from warrior culture, they were bred for fighting, and thriving in the most physically demanding places imaginable. whites have thicker skin, denser bones, higher lung capacity, stronger tendons and ligaments, build muscle faster, have wider frames, better immune systems, and live longer
What is the fact of the lungs of the world?
Lungs of the world, the amazon is getting devastated and/or shaved off
What is the general function of the lung?
the specific function of the lungs is to help air pass throw the the lungs
another answer is when you breath the air (oxygen) goes into the lungs
The lung has to constantly expand and contract during the exchange of gases. Besides, the alveoli of the lung has to be moist and spongy in order to maximize the surface area to effect the maximum transfer of gases.
What are the benefits of an increased lung capacity?
a good lung capacity has to have room and a large chest cavity
How are the lungs provided with a continuous supply of clean atmospheric air?
hairs in the nostrillstrap dust. epithelium which lines the inside of the trachea bronchi and bronchioles consists of ciliated cells. dust particles and bacteria become ytrapped in the sticky mucus film and the mucus is carried away from the lungs by the flicking movements of the cilia
Carbon monoxide
Names of tubes that carry air to lungs?
The main air tube in your throat is called the trachea. You can feel its ridges of cartilage along the front of your neck. The trachea has two branches called bronchi which are also strengthened by cartilage. They lead to the lungs. The next smaller branches are called bronchioles; they are soft without cartilage since they are inside the lungs. The bronchioles lead to the alveoli where the work of the lungs takes place.
Why does hemoglobin accept oxygen molecules in the lungs but give up oxygen molecules in tissue?
In the lungs where the oxygen concentration is high the binding of oxygen tohemoglobin is high. In respiring tissue where the oxygen levels are low and the CO2 levels are high the affinity of hemoglobin for oxygen is reduced and so the oxygen comes off the hemoglobin and is used by the cells. The driving force for this is the Bohr Effect whereby CO2 produced by the respiring cells dissolves in the blood as follows
CO2 + CO2 --> H2CO3 --> H+ + HCO3-. The H+ produced bind to the hemoglobin and in doing so displace the oxygen
