Lungs

My pulmonologist tells me that the granuloma tumors that I have in my lungs (four in the left lung and one on the right) is from the COPD. He has ruled out sarcoidosis. I would like to know that are the chances that these granuloma tumors will turn cancerous.

Bronchioles.

The body gets rid of several waste products from the lungs. And in fact, exhalation is the primary route of removal for some "xenobiotics" (materials that are not supposed to be in the body).

Carbon dioxide

Base of the lung

The amount will vary upon the type of breathing we are doing. During relaxed breathing or tidal volume can be only a small portion of the entire lung capacity, and at vital capacity is the measure of the total amount of air that can forcibly be moved in and out of the lungs in one breath with the additional help of muscles; abdominals, intercostals, pectoralis minor, and scalenes.

An average adult at rest breathes in and exhales out about 500 mL of air 12 to 20 times in a minute. Women typically breathe about the same rate with a slightly lower volume. Children take more breaths per minute but the tidal volume is lower.

The air travels down into your lungs and into small air pockets called capillary The air is then transferred through the capillary as they are really thin. Oxygen from the air is taken in and used around the body and the excess carbon dioxide is breathed back out as t is not needed in the body.

You lungs also get bigger as you take a breathe, this creates a larger surface area as the chest goes out. The chest gets smaller as you breathe out as your lungs relax.

Your diaphragm is located below your lungs. When you relax your muscles, your diaphragm is shaped like a dome.

The lungs are the site of gas exchange, meaning that oxygen will enter your blood and carbon dioxide will leave your blood in the lungs. Oxygen is needed to generate energy in cells and carbon dioxide is a waste product that can acidify the blood if not expelled.

Rapid breathing can lead to a condition called hyperventilation. Hyperventilation occurs when a person breaths more rapidly than the body demands. When a person hyperventilates, the CO2 blood concentration (partial pressure) decreases below normal levels.

They extract oxygen from the air.

You can't - lungs are vital organs in humans that a person cannot survive without. We can supplement oxygen to lungs and help extremely damaged lungs function well enough to maintain life (sometimes), but you still have to have lungs to breathe and live.

blood entering the lungs has a partial pressure of oxygen (PO2) of 40 mmHg and a partial pressure of carbon dioxide (PCO2) of 46 mmHg; alveoli, on the other hand, have a PO2 of 105 mmHg and a PCO2 of 40 mmHg. As the blood moves past the alveoli, oxygen and carbon dioxide will diffuse down their respective partial pressure gradients.

Oxygen will move from the alveolar space (PO2 of 105 mmHg) to the blood stream (PO2 of 40 mmHg). Carbon dioxide will move from the blood (PCO2 of 46 mmHg) to the alveolar space (PCO2 of 40 mmHg).

As the blood leaves the alveolus, the PO2 and PCO2 will have essentially equilibrated with the alveolar air.

Bronchiovascular marking in the lungs are nothing but the normal making of the blood vessles of the lungs which are supplying to the bronchi and bronchiols these marking are increase in the case of any infection or inflammation.These are reconized by the prominent low density liner opacities in the lungs feild these are more prominent on the hilar region which is suggestive of an infection or inflammation. for more answers and help contact me on amjadkhan.mmkk@gmail.com thanking you

In air through the passageways to the lungs, by diffusion through the alveoli into the blood, by diffusion out of the blood into the cells and through the cells into the mitochondria - where it ceases to exist as oxygen and becomes water.

The lung capacities are measurements of two or more volumes. The vital capacity (VC) measures the maximum amount of air that can be inhaled or exhaled during a respiratory cycle. It is the sum of the expiratory reserve volume, tidal volume, and inspiratory reserve volume. The inspiratory capacity (IC) is the amount of air that can be inhaled after the end of a normal expiration. It is, therefore, the sum of the tidal volume and inspiratory reserve volume. The functional residual capacity (FRC) includes the expiratory reserve volume and the residual volume. The FRC measures the amount of additional air that can be exhaled after a normal exhalation. The total lung capacity (TLC) is a measurement of the total amount of air that the lung can hold. It is the sum of the residual volume, expiratory reserve volume, tidal volume, and inspiratory reserve volume

The man with the largest lung capacity is a 6'5" rower who now rows for team GB and won a silver medal in the Olympics recently I can not remember his name though.

His name is peter reed, he won gold in the Olympics in the coxless four, Australia came second.

In the lungs, the respiratory zones end in sacs called alveoli, which are the site of gas exchange. The alveoli have walls only one cell thick, and are surrounded by pulmonary capillaries which again have walls only once cell thick; gases diffuse, along their concentration gradients (i.e. from the area of high concentration to the area of low concentration), through these two thicknesses of cells.

No, bronchioles (except in the whale) do not contain cartilage.

The bronchioles in whales contain cartilage in order to prevent them from collapsing before other parts of the airways (and trapping gas in the alveoli). This helps prevent the bends - as nitrogen is removed from the alveoli before large pressures cause it to diffuse across the thin walls present there.

A blood clot on the lung is called an emboli. The term embolus means the process of forming emboli.

Total lung capacity is defined as the volume in the lungs at maximal. Regular aerobic exercise strengthens and tones the heart and lungs, enabling the pulmonary system to increase the maximum amount of oxygen that the lungs can handle.

I was informed that it was about 75 to 80%. Right, wrong, or ?

Because lung abscess is a serious condition patients need quiet and bed rest. Hospital care usually includes increasing the patient's fluid intake to loosen up the secretions in the lungs, and physical therapy to strengthen the patient's breathing muscles

When inhaling, the hairs in the nostrils and villi throughout the whole respiration tract clean the air, by removing the dirt from inhaled air. This dirt is excreted as mucus and is coughed up. - Smokers tend to collect more mucus and dirt in their lungs and cough it up more as they damage their small villi hair through the tobacco smoke. The air they are breathing is also dirtier, so their is a higher percentage of particles collected.

The respiration system is through the mouth/nose, down the trachea, through the bronchi, into the bronchioles, which seperates out into alvioli.

The lungs are the essential organs of respiration; they are two in number, placed one on either side within the thorax, and separated from each other by the heart and other contents of the mediastinum (Fig. 970). The substance of the lung is of a light, porous, spongy texture; it floats in water, and crepitates when handled, owing to the presence of air in the alveoli; it is also highly elastic; hence the retracted state of these organs when they are removed from the closed cavity of the thorax. The surface is smooth, shining, and marked out into numerous polyhedral areas, indicating the lobules of the organ: each of these areas is crossed by numerous lighter lines. 1
