Thank you for your question. I'm sorry to hear about your uncle.
Water in the lungs can be called:
Lung/pulmonary congestion, Congestive heart failure, Lung water, Pulmonary edema
Edema is swelling of any organ or tissue due to accumulation of excess
fluid. Edema has many root causes, but its common mechanism is
accumulation of fluid into the tissues.
"Your lungs are two spongy organs surrounded by a moist membrane (the
pleura). Stretched out, they would cover about 100 square yards ? the
size of a badminton court. Although your lungs can hold up to 4 quarts
of air, you generally inhale only about a pint of air with each
Two major airways (bronchi) carry air into your lungs. These airways
subdivide into smaller airways (bronchioles) that finally end in
clusters of tiny air sacs. Your lungs have about 300 million of these
air sac clusters, which inflate like miniature balloons every time you
Wrapped around each air sac are tiny capillaries that connect the
arteries and veins in your lungs. The capillaries are so narrow that
red blood cells have to pass through them in single file. Each red
blood cell absorbs oxygen, while the plasma ? the fluid containing the
red blood cells ? releases carbon dioxide.
But in certain circumstances the alveoli fill with fluid instead of
air, preventing oxygen from being absorbed into your bloodstream. A
number of factors can cause fluid to accumulate in your lungs, but
most have to do with your heart (cardiac pulmonary edema).
Understanding the relationship between your heart and lungs can help

How do the lungs work?
"The lungs are a pair of sponge-like organs, which are located inside
the rib cage. The right lung has three sections, called lobes, and the
left lung has two. The airways are a series of hollow tubes, which
allow oxygen to enter into the lung tissue as we breathe.
As you breathe in, oxygen enters the windpipe (trachea), goes through
the airways (bronchus and bronchioles) and into small sacs called
alveoli. The alveoli are surrounded by blood vessels. The oxygen
crosses into the bloodstream from the alveoli and is then carried to
the rest of the body. Oxygen is needed to allow cells in our body to
function normally. The heart pumps the blood, which carries the
The area in between the lungs is called the mediastinum. Lymph nodes,
the heart, large blood vessels, the trachea (windpipe) and the
esophagus (food pipe) are located here.
A thin membrane covers the surface of the lungs and is called the
visceral pleura. A membrane also lines the chest wall and is called
the parietal pleura. These membranes allow the lungs to slide as we
breathe in and out.
The lymphatic system is a network of vessels, which filter bacteria
and other foreign material, in order to help fight infection or
disease. Tumor cells can spread (metastasize) through the blood
vessels and lymphatic system. Lymph nodes are a part of the lymphatic
system. They are nodules along the vessels of the lymphatic system
that filter germs and other foreign material such as cancer cells.
These nodes swell when cells become trapped.
"Symptoms of pulmonary edema include difficulty breathing, coughing up
blood, excessive sweating, anxiety and pale skin. If left untreated,
it can lead to death, generally due to its main complication of acute
respiratory shock syndrome."
relating to, functioning like, or associated with the lungs
Causes, incidence, and risk factors:
"Pulmonary edema is usually caused by heart failure that results in
increased pressure in the pulmonary (lung) veins. However, problems
within the lungs themselves can also result in fluid accumulation.
Pulmonary edema can be a complication of a heart attack, leaking or
narrowed heart valves (mitral or aortic valves), or any disease of the
heart that either results in weakening and/or stiffening of the heart
muscle (cardiomyopathy). The failing heart transmits its increased
pressure to the lung veins. As pressure in the lung veins rises, fluid
is pushed into the air spaces (alveoli). This fluid then becomes a
barrier to normal oxygen exchange, resulting in shortness of breath.
Pulmonary edema can also be caused by direct lung injury from toxins
including heat and poisonous gas, severe infection, or an excess of
body fluid as seen in kidney failure."
Because this cancer starts in hormone producing cells in the lung, it
can cause unique sodium and water problems. For example, tumor cells
may secrete adrenocorticotropic hormone, causing Cushing's disease.
Tumors may secrete antidiuretic hormone, leading to water retention
and low sodium, which causes confusion.
Pulmonary Edema Symptoms & Signs
(Click on blue links on the page for more information on the following symptoms)
Shortness of breath
Feeling of "air hunger" or "drowning"
Grunting or gurgling sounds with breathing
Shortness of breath with lying down, causing the patient to sleep with
head propped up or using extra pillows
Additional symptoms that may be associated with this disease:
Coughing up blood
Inability to speak from air hunger
