Lungs

It depends are what your trying to do. If you want to run longer, run more. Run around the block or go to the park and jog for about 15 minutes a day. When that becomes easy, run longer. Keep increasing the time you run periodically until you reach your goal.

The need for oxygen therapy is not solely determined by lung capacity but also by symptoms of low oxygen levels. If you have 60% lung capacity but are not experiencing significant symptoms, you may not need oxygen therapy. It would be best to consult with a healthcare provider for a proper assessment and recommendation.

Stomach cancer or gastric cancer.

If the cancer start in the glandular system it is called adenocarcinoma.

Other types of cancerous tumors are: lymphoma, gastric sarcoma and carcinoids tumors.

Alveolar dead space is the difference between anatomical and physiologic dead space, representing the space of alveoli occupied by air that does not participate in alveolar ventillation (oxygen-carbon di oxide exchange). Anatomical dead space: the Airways of mouth, nose, pharynx, larynx, trachea, bronchi, and the broncheoles. Equipment dead space is the volume of equipment that occurs in rebreathing of gases. Physiologic dead space is the sum of the anatomic and alveolar dead spaces Its volume VD is determined by measuring the partial pressure of carbon di oxide in a sample of exhaled gas (PE) and with tidal volum e(VT) using the formula VD/VT =[ (PCo2-PECo2)/PaCo2

Subpleural bullae are focal regions of emphysema with no discenible wall. If the blebs rupture, the inhaled air escapes from airways into the thoracic cavity and causes pneumothorax or lung collapse. It is usually treated with oxygen therapy and surgery.

The condition where the lung tissue collapses is called atelectasis. This occurs when alveoli in the lungs deflate, leading to reduced gas exchange and potential respiratory issues. Atelectasis can be caused by various factors such as blockage of airways, pressure on the lungs, or underlying lung diseases.

Bleeding from the lungs is called pneumorrhagia.

Jesus' ministry was full of examples of his compassion for any physical suffering.Here are a few examples.In Matthew nine verses one to eight He healed the man who was crippled.In verse 27 the blind man was healed and another in Matthew 20 verse 29.The man with the withered hand was healed in Mark three verse one to five.Mark seven verses 31-37 tells of the deaf man being made able to hear and speak.That's more than three but there are many others that tell of his physical care for the disabled-not to mention his spiritual care for them.

Lung cancer decreases the organism's ability to absorb oxygen and expel carbon dioxide, which can result in exercise intolerance, fatigue and a general lack of ability to move around effectively. It may also cause chest or rib pain. Eventually, the cancer will spread enough that the organism will die of it or a complication of the cancer.

While bacteria themselves do not directly cause cancer, certain bacterial infections have been linked to an increased risk of cancer development. Here are some examples of bacteria associated with cancer:

Helicobacter pylori (H. pylori):

H. pylori is a bacterium that infects the lining of the stomach and is a major risk factor for gastric cancer and gastric mucosa-associated lymphoid tissue (MALT) lymphoma. Chronic infection with H. pylori can lead to inflammation of the stomach lining, which over time may promote the development of cancerous lesions.

Human Papillomavirus (HPV):

HPV is a sexually transmitted infection known to cause cervical cancer, as well as other cancers of the anogenital region and oropharynx. Certain high-risk strains of HPV, such as types 16 and 18, can infect epithelial cells and lead to the formation of precancerous lesions. Persistent infection with high-risk HPV strains increases the risk of these lesions progressing to invasive cancer over time.

Helicobacter hepaticus:

Helicobacter hepaticus has been associated with an increased risk of liver cancer in animal models. Chronic infection with this bacterium can induce chronic inflammation in the liver, which may promote the development of cancerous tumors over time.

Chlamydia trachomatis and Neisseria gonorrhoeae:

These sexually transmitted bacteria have been linked to an increased risk of cervical and prostate cancers, respectively. Chronic inflammation resulting from these infections may contribute to cancer development in the affected tissues.

Streptococcus gallolyticus (formerly Streptococcus bovis):

Streptococcus gallolyticus has been associated with an increased risk of colorectal cancer, particularly in individuals with underlying gastrointestinal conditions such as inflammatory bowel disease. Chronic inflammation and tissue damage caused by this bacterium may contribute to cancer development in the colon or rectum.

While these bacteria may increase the risk of cancer development, it's important to note that not everyone infected with these bacteria will develop cancer. Additional factors, including genetic predisposition, environmental exposures, and lifestyle habits, also play a role in cancer development. Preventive measures such as vaccination (e.g., HPV vaccine), screening and treatment of bacterial infections, and practicing safe sex can help reduce the risk of cancer associated with bacterial infections. Additionally, maintaining a healthy lifestyle, including a balanced diet, regular exercise, and avoiding tobacco and excessive alcohol consumption, can contribute to overall cancer prevention efforts.

Yes, cancer can sometimes have a hereditary or genetic component. Some individuals may inherit gene mutations from their parents that increase their susceptibility to developing certain types of cancer. These inherited genetic mutations are associated with an increased risk of cancer, but they do not guarantee that cancer will develop.

There are certain genes known as tumor suppressor genes and oncogenes that play crucial roles in regulating cell growth and preventing the formation of tumors. Mutations in these genes can lead to uncontrolled cell growth and an elevated risk of cancer.

Two common types of hereditary cancer syndromes are:

Hereditary Breast and Ovarian Cancer (HBOC):

Mutations in the BRCA1 and BRCA2 genes are associated with an increased risk of breast and ovarian cancers. Individuals with these mutations have a higher-than-average risk of developing these cancers, as well as an increased risk of certain other cancers.

Lynch Syndrome (Hereditary Nonpolyposis Colorectal Cancer - HNPCC):

This syndrome is caused by mutations in genes involved in DNA repair, such as MLH1, MSH2, MSH6, and PMS2. Lynch Syndrome is associated with an elevated risk of colorectal cancer and an increased risk of other cancers, including endometrial, ovarian, and stomach cancers.

It's important to note that while hereditary factors can contribute to an increased risk of cancer, the majority of cancers are not directly inherited. Most cancers are believed to result from a combination of genetic, environmental, and lifestyle factors.

If there is a family history of certain types of cancer, genetic counseling and testing may be recommended. Genetic testing can identify whether an individual carries specific mutations associated with an increased cancer risk. This information can help individuals and their healthcare providers make informed decisions about monitoring, prevention, and early detection strategies.

If you have concerns about your risk of developing cancer based on your family history, it is advisable to discuss these concerns with a healthcare professional or a genetic counselor. They can provide guidance on genetic testing and help assess your individual risk factors.

Rarely increased in women with early breast cancer, it may be used to detect recurrence of cancer in women following treatment or mastectomy and to monitor treatment for women with advanced breast cancer.

Leukemia is a cancer that affects the blood and bone marrow. It is characterized by the abnormal production of white blood cells, which are essential for the immune system. In leukemia, the bone marrow produces large numbers of abnormal white blood cells that do not function properly. These leukemia cells can crowd out normal blood cells, leading to problems with blood clotting, anemia, and a weakened immune system.

There are different types of leukemia, and they are classified based on the type of white blood cell affected (lymphoid or myeloid) and whether the disease is acute or chronic. Acute leukemia progresses rapidly and requires immediate treatment, while chronic leukemia progresses more slowly and may not cause symptoms for many years.

Common types of leukemia include acute lymphoblastic leukemia (ALL), acute myeloid leukemia (AML), chronic lymphocytic leukemia (CLL), and chronic myeloid leukemia (CML). The specific type of leukemia and its classification influence the treatment approach and prognosis for individuals affected by the disease.

Pulmonology is a medical study that deals specifically with problems regarding the lungs and the respiratory tract.

Air enters through the nose or mouth, this air then travels down the wind pipe, past the voice box and to the lungs. The lungs divide into two small tubes called bronchi, these bronchi then split into thousands of tiny tubes called bronchioles, at the end of these tiny bronchioles are millions of small 'air sacs' called alveoli. Once in the alvoli gas exchange of carbon dioxide and oxygen in the capillary walls happens.

The oxygen which you have breathed in through your nose or mouth is diffused through the capillary walls to meet red blood cells, which then take the oxygen to the heart, where it pumps the blood cells to cells all over the body that need oxygen to function and do its job correctly.

when this oxygen reaches the cells it kind of 'swaps' positions with the carbon dioxide (CO2) which has been created as a waste product by the body's cells.

Once the CO2 is attached to the blood cells, it is returned to the heart where it pumps the blood cells back to the lungs, where gas is diffused again and the cycle starts again.

sorry, a bit confusing.

Of course, what were you thinking of mosquitos not having lungs.

Through the placental tissues that join the mother's bodily systems to her fetuses' systems. The umbilical cord is connected to the placenta, which aids in this transmission process, and the placenta is connected to a vast network of capillaries and blood vessels in the sow's uterus and uterine horns which flow throughout the sow, supplying blood and oxygen to her babies and exterminating wastes that are expelled by the fetuses.

Elephants are mammals and they have lungs.

Yes they do.All sea creatures have gills.

No. SCID, or severe combined immunodeficiency, is a disease of the immune system wherein important signaling molecules called interleukins are incapable of transmitting messages to other cells of the immune system. Since some immune cells use interleukin communication to ward off cancer, SCID can predispose individuals to some cancers. But SCID is not a form of cancer in itself.

This could mean several things; the two most common being a dental problem or a physical injury. In either case, bleeding from the mouth should be treated as an emergency and should be looked at by a vet immediately.

No, but crocodiles can hold their breath under water for long periods of time if needs be (some large adult crocs have been known to hold their breath for 2 hours or more!)

yes of course! then how they live on land
