Lungs

It depends on your psychosomatic system. In most cases, pulmonary damages worsen after 60-70 years. But lung cancer due to smoking can develop in late thirties.

It really has no function just as in any other fetus. Blood flow to the tissues there are at a normal rate just as to the feet and head. It isn't until the fetus is born that the lungs function as a gas exchange organ.

In a cell in the human body diffusion takes place in the cell membrane. The cell membrane allows smaller sized molecules to pass through.

Internal respiration

the lungs close up, which closes off the passage ways from the esophagus and the stomach and the lungs. the passage ways are divided by the esophageal sphinxter. which helps divide what objects go where, food goes down the esophagus into the stomach while air goes down the tubuals down into the lungs. if you have a disfunctional esophageal sphinxter you have a greater chance of getting often re-occurences of GERD otherwise known as Acid Reflux, which results in Stomach Acid occurring in the Tubes of your Esophagus.

the lungs can better exchange oxygen and waste products in the blood.

The visceral pleura (a thin membrane protecting the lungs) is attached directly to them. There is another pleura on the outside of this (attached to the thoracic cavity), it is called the parietal pleura, between them is a serous fluid that acts as a sort of cushion.

quality assurance is a maintain and control the quality of radiation treatement machine.we are treating the patien with radiation.if execes of dose receive it can induce secondary malignancee.so we have to qa dosimetry for radiation treatement.

The extension of a bronchile refers to any fine thin walled tubular extensions of the bronchus.

Air tends to flow from high pressure to low pressure. If the pressure in the lungs exceeds that pressure at the mouth (which is usually atmospheric pressure), then air will flow out of the lungs. During normal inhalation, the diaphragm muscle contracts, pushing the abdominal contents, but increasing the volume on the thoracic cavity (the chest). Since at first the volume of the lungs increases as it is pulled with the diaphragm, the intrathoracic pressure decreases, and air moves into the lungs.

If the pressure in the lungs were to increase relative to the air at the lips then air would move out. The elasticity of the lungs tends to make the lungs want to assume a smaller size (like the elasticity of a stretched rubber band). This force in addition to the force of expiratory muscles if they are being used will increase pressure in the lung (under normal circumstances this is basically intrathoracic pressure). However, the velocity of the flow of air is limited by airways resistance. [This is similar to V=IR from electricity voltage = current x resistance] In the case of the lung, the flow is proportional to the change in pressure (delta pressure intrathoracic pressure vs atmospheric pressure) and inversely proportional to the airways resistance. So resistance in the air passages with slow the flow of air out of the lung.

Now you might think that one could easily overcome airways (air passages) resistance's negative affect on flow by increasing the pressure in the lungs. Unfortunately this cannot be done without increasing the airways resistance too. Because as I try to squeeze air out of my alveoli with more pressure that pressure is transmitted throughout the lung and to my small airways that are compressible and thus if a bear were to hug me and try to squeeze air out of me faster this would also increase the airways resistance by narrowing some of the small airways, increasing resistance and decreasing flow.

whatever is snorted passes through the nasal cavity, then proceeds to the lungs, like anything you inhale.

Smoking makes lungs dirty, coating them with tar and soot, which interferes with their normal functioning. Prolonged smoking can cause several kinds of lung disease including emphysema and lung cancer, which seriously interfere with normal lung function.

yes I have phlegm in my throat already a few years and I can;t get rid of it.help me please.
