What Are The Main Parts Of The Lungs
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)?
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?
Varies: Metastatic spread can cause all kinds of pain, lumps, fractures etc. There are some signs of bone pain without spread called pulmonary osteoarthropathy and clubbing may be a sign. There are some tumors with endocrine effects.
I have a TB on the lymph node. Do the bacteria can spread to the other parts on the body especially lungs?
Yes, tuberculosis: Is an infection caused by bacterium. It can affect any organ. You need to have proper anti-tb treatment.
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?
I've been breaking out with a rash on differnt parts of body for last several days, plus yesterday my lungs have started burning and have bad cough,?
Rash and cough: There are many possibilities but you likely have an infectious process and may be contagious. As you are having increasing symptoms and your lungs are involved, you should see your doctor or go to an urgent care as soon as possible. You need full evaluation and treatment. Avoid contact with others until you know what you have.
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
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.
If you have pleural effusion, does the liquid collect to the lower parts of the lung when sitting? Doctor only checked lower part of back with doppler
Yes: Rarely, the fluid collection gets walled in and become fixed. But otherwise the collection will fill the lower parts first on gravitational force.
TB: It can. The primary focus is usually the right lower lobe because that is the easiest site of entry for inhaled droplet nuclei containing afb. When the infection reaches the local nodes they suppurate, erode into an adjacent artery and the m. Tbc then spreads throughout the body to the areas with most blood flow. Either the patient then forms multiple granulomas or goes on to develop miliary tb.
Have 2 low grade tumors in the lungs and kidney with the lungs being primary. Would the next tumor they are going to biopsy be low grade as well?
Lung Tumor: If I understand you correctly, you have a low grade lung tumor that has spread to the kidney, and not two separate tumors. As a general rule, a new metastasis will have the same morphology as the original tumor, but, even so, a metastatic lung tumor, even if it is "low grade, " requires immediate treatment, which may include surgery, chemotherapy and irradiation, depending on the diagnosis.See 2 more doctor answers
Maybe: Some primary TB infections leave scars in the lung that might show up on chest Xray, but not necessarily. Many (most?) people have entirely normal Xrays after primary TB.
Pneumonia: Primary lung infection most commonly means pneumonia. Regression means that the infection has decreased since the last study. Hyperaerated lungs can mean that the patient took an intentional deep inspiration or that there is air trapping due to airway blockage, which can be due to asthma, COPD, and other causes.
Pneumonia with COPD: It usually means that you have pneumonia with air trapping or obstructive pulmonary disease (chronic bronchitis or asthma). The pneumonia is usually treated with antibiotics. The hyperaeration may be secondary to the pneumonia and resolve as the infection does. If it is from smoking or reactive airways, steroids and bronchodilators may be necessary (as well as to quit smoking).
Does every Primary Complex diagnosis cause scars on the lungs? Is this lifetime or any lung scar can clear up?
Primary complex: Not every primary complex leaves a lung scar seen on X-Ray. It usually takes some calcification or growth of granulation tissue to be seen. Some of them heal completely without Leaving any trace.
Had primary pneumothorax 2 weeks ago, they did VATS and removed bullae. Can pneumothorax reappear again? Also, is lung capacitty now smaller? Thanks
1) Yes 2) Maybe not: Without a complete history, I am only speculating, but -- 1) If you have other bullae now or new ones develop in the future, you do have a risk of recurrence. 2) Bullae are often not functional and take up space in the chest that could be used by functional lung - by removing them you can actually increase lung function.See 1 more doctor answer
