what is a hilar mass?
481572
A hilar mass just means that on a chest x-ray or CT/MRI scan, one sees that the center of the chest area seems enlarged. It could mean many things, but a common reason is that the lymph glands there are enlarged. This could be cancer, but it could be something else entirely, so talk to your doctor about it. Good luck.

Mass is the ammount of space a thing takes up. Density is how hard/solid an object is. Volume is the inside of something (similar to area.) Sorry if my answers aren't enitelry correct!

The diaphragm is a muscle separating the thorax, or chest cavity from the abdominal cavity.  It is convex (rounded on top) and when a breath is taken, it flattens out - thereby increasing the space in the chest cavity. (At the same time, the rib cage expands).  When the space in the chest cavity increases, the pressure in the chest cavity decreases in relation to atmospheric pressure....this decrease in pressure is what causes the "breath" to enter the lungs.

Sounds like something more serious. see a md.

it has the greatest mass

It has no mass. But it has relative mass of ≤ 1. It is a matter.

In meteorology, an airmass or air mass is a large volume of air having fairly uniform characteristics of temperature, atmospheric pressure, and water vapor content. Air masses cover many hundreds or thousands of square miles, and slowly change in accordance with the terrain they are over.

The mass is a property of an object, a fundamental measure of the amount of matter in the object. The usual symbol for mass is m and its SI unit is the kilogram.\n\nThe weight of an object is the force of gravity on the object and may be defined as the mass times the acceleration of gravity, w = mg. Since the weight is a force, its SI unit is the newton.

Hiccup\n\nA hiccup or hiccough (generally pronounced "HICK-up" (IPA: /ˈhɪ.kəp/) independent of the spelling) is an involuntary spasm of the diaphragm; typically this repeats several times a minute. The sudden rush of air into the lungs causes the glottis to close, creating the "hic" noise. A bout of hiccups generally resolves by itself, although many home remedies are in circulation to shorten the duration, and medication is occasionally necessary. By extension, the term "hiccup" is also used to describe a small and unrepeated aberration in an otherwise consistent pattern. The medical term is singultus.\nWhile many cases develop spontaneously, hiccups are known to develop often in specific situations, such as eating too quickly, taking a cold drink while eating a hot meal, eating very hot or spicy food, laughing vigorously or coughing, or drinking an excess of an alcoholic beverage. Hiccups may be caused by pressure to the phrenic nerve by other anatomical structures, or rarely by tumors.\nIt is still unclear to scientists exactly why hiccups occur, particularly because it doesn't seem to give us any specific benefit. Some speculation exists that hiccups are a remnant of a bodily function that has been phased out by evolution, such as the move from aquatic gilled creatures to land animals. More research is required to ascertain their true nature, origins, and purpose, if any.\n\nHome remedies\nThe following are some commonly suggested home remedies. While numerous remedies are offered, they mostly fall into a few broad categories. These categories include purely psychosomatic cures centered around relaxation and distraction, cures involving swallowing and eating (with the rationale generally that this would remove irritants or reset mechanisms in the affected region), and cures involving controlled/altered breathing.\nWhile the first two categories may prove effective for many short lived and minor cases of hiccups, those suffering from an intractable case may become desperate sorting through various ineffective home remedies. Many of the cures centered around controlled breathing (i.e. holding breath) are often ineffective. The only underlying rationale could be the displacement of an irritated nerve through prolonged diaphragmatic expansion.\nHowever, one respiratory remedy has a fairly sound rationale underlying it. Breathing into a bag or small enclosed container (ensuring that it is completely sealed around the mouth and nose) induces a state that is termed respiratory acidosis. The effect is caused by increasing the amount of inspired carbon dioxide, which then increases the serum level of carbon dioxide. These increased levels of CO2 lower the pH in the blood, hence creating a state of acidosis. This state of acidosis produces vasodilation and depression of the central nervous system. The effect allows for increased blood flow to the affected muscles, and suppression of the aberrant nervous impulses. Inducing a state of acidemia through hyperventilation is particularly effective in curing hiccups because the diaphragm rests directly against the pulmonary vasculature that is then flowing with especially low pH blood. This is a potentially dangerous action; and should only be done with another person present. As the serum CO2 level rises abruptly, the person will begin to feel lightheaded and within a few minutes will pass out. If done without a spotter, the person might either injure him or herself as he or she passes out, or pass out in such a way that the bag or container continues to prevent oxygen intake (see also asphyxia).\nAdditionally, another respiratory remedy, while having no sound scientific principle behind it, is paradoxically one of the most effective in treating persistent hiccups. One breathes out all the air that they are able to in one long exhalation then breathes in all the air they feel they possibly can in one continuous inhalation. The person then attempts to b

Its called the pleura, I found it for you on a cancer website-lol hope this helps

Density is defined as mass divided by its volume. If you want to know the volume, then divide the mass by its density; if you want to know the mass, just multiply the density by its volume.
