Lung (Definition)

Deoxygenated blood enters the lungs from the right side of the heart and travels to the lungs. When you inspire, oxygen flows into the lungs, transverses the capilliares and attaches to hemoglobin down a gradient. At the same time, co2 diffuses into the capilaries and is expelled with exhalation. Oxygen rich blood then flows to the left side of the heart and into the ...Read more

Does the composition of blood change as it passes through different parts of the body (e.g. the intestines and the lungs)?

Does the composition of blood change as it passes through different parts of the body (e.g. the intestines and the lungs)?

Well sure...: More oxygen/less CO2 in blood after passing thru lungs; more absorbed nutrients after passing thru gut; first-pass metabolism occurs in liver; reduced nitrogenous waste after passing thru kidneys, etc. ...Read more

Have 2 low grade cancerous tumors already in two separate parts of the body lungs/kidney would the next tumor found and being biopseed be low as well?

The grade: Is not as crucial as the cell type. It says you are using o2. Both lung and urothelial cancers are smoking related. Should you develop a third cancer, having 2 low grade cancers conveys no information about a third. Have you sought genetic testing? ...Read more

What parts of the spinal cord tell the heart to beat and the lungs to breath so if it was damaged, you could die pretty suddenly?

Vagus Nerve: Comes directly from the brain, not from spinal cord, controls heart & lungs. Phrenic nerve controls the diaphragm this comes off from cervical nerves in the neck C3 -c5, so you would have to damage spinal cord high in the neck to affect breathing. ...Read more

If you had lung cancer that has spread to other parts of your body would it probably be big enough to be seen on X-ray or your blood work be off?

If you had lung cancer that has spread to other parts of your body would it probably be big enough to be seen on X-ray or your blood work be off?

Yes and no: When Cancer starts to spread, it begins as clusters of cells that form tiny colonies in other body parts. These will grow in size over a few months to become visible on X-rays and various diagnostic imaging tests such as CT scan and or PET scan. Blood tests do not show cancer cells, so we rely on the above imaging tests and repeat them periodically (every 2-3 months) to monitor for the tumor growt ...Read more

If parts of the lung became hypoxic but the rest of the body had enough oxygen, would this still cause a short of breath feeling?

If parts of the lung became hypoxic but the rest of the body had enough oxygen, would this still cause a short of breath feeling?

Theoretically...: Consider ventilation-perfusion mismatches classically shown by V/Q scans. To deliver oxygen & release carbon dioxide, you need circulating capillaries & open alveoli. "Parts of the lung [becoming] hypoxic" is not exactly the right phrasing. But, along those lines, if you had a lobe collapse, an embolus, or pulmonary edema, if large enough, they will impact ventilation & cause shortness of breath. ...Read more

I am unable to take in deep breaths unless I try really hard. Seem to lost the function. Are my lungs damaged. Any. Other possibility?

I am unable to take in deep breaths unless I try really hard. Seem to lost the function. Are my lungs damaged. Any. Other possibility?

Need full lung eval: Most of the time when you cannot take a deep breath it is because a discomfort (mainly pain) prevents you from taking a deep breath - a muscle strain, rib contusion, lung problem or gastrointestinal issues can cause this. In the absence of such issues it is rare but possible that pure motor weakness can cause you to feel this way - you need a full evaluation at a doctor's office/. ...Read more

When I am tired, I feel like I'm not getting enough oxygen and my lungs won't expand fully. Is this a normal function?

Yes: It's not unusual for me to see patients who are tired/ not getting much exercise who feel a need to sigh deeply, feeling they can't quite get that deep breath they need to satisfy them. The only two things I have found that help them are more rest and more exercise. There are some stretch receptors in the lungs which I believe are playing a role in this problem. ...Read more
