the simple answer is drowning. Blood is a fluid just like water, and it causes the same effect as drowning.
It picks up oxygen
A lung is an organ in your chest, that when you breathe in, it fills with air and puts that air into blood which comes from the heart, and than sends it back to the heart to go throughout the body. when you breathe out, bad gases from your blood comes out called carbon dioxide.
Hemothorax is a collection of blood in the space between the chest wall and the lung (the pleural cavity).
A blood clot in the heart could affect the lungs in a number of ways. It could potentially block the pulmonary artery and prevent blood from traveling from the heart to the lung. That would reduce the amount of nutrients reaching that lung and the lung could suffer damage. The blood clot could also travel into the lung (if it is small enough to move through the pulmonary artery) and block blood flow into and out of the lung. The person usually feels short of breath and may cough up blood if that happens. This is called a pulmonary embolism and can be fatal if untreated.
Can't breath and you die cause your lungs with dry out too much .
Tension pneumothorax which is where the lung cavity fills with air and crushes the remaining good lung.
alot
blood
The veins.
There is an exchange with oxygen, nutrients, and carbon dioxide and water vapor.
absorpition of oxygen from the blood into the lung
Pneumonia fills the lung's alveoli with fluid, keeping oxygen from reaching the bloodstream.
