Lungs

Many mammals have cartilage rings in their tracheas, which may also extend down the mainstem bronchi. These rings are in place to physically keep the major airways propped open so that air can flow easily.

I have no idea if it causes cancer or not, but who wants to be in pain during sex. Most guys think rough play turns a woman on but the truth is it shuts them off.

There are MANY diseases that can affect the lungs of human beings. The most common seems to be Bronchitis and C.O.P.D (Chronic Obstructive Pulmonary Disease). Various types of Lung Cancer exist as well.

Monotremes are mammals; therefore they have lungs, not gills.

For most eye cancers, there are no early signs. They would need to be discovered by an ophthalmic exam in their early stages. The exception would be a superficial surface eye cancer, like the elevated type that originates from the very outer coating of the eye. Again, your ophthalmologist's examination is the best way to distinguish the lesion from one that is not cancerous.

Deoxygenated blood goes to the lungs to get rid of carbon dioxide and to pick up oxygen.

The lungs are the site of gas exchange in mammals. Lungs ensure that efficient gas exchange takes place between the air and the person's blood. The lungs are a pair of lobed structures made up of a series of highly branched tubules called bronchioles, which end in tiny air sacs called the alveoli (the alveolar membrane is the site of gas exchange). Lungs allow us to take in oxygen from the external air and allow us to get rid of excess carbon dioxide. They are the structures that help us breathe and they are an important part of our life.

Age affects lung capacity. This is because aging causes the alveoli to lose its shape and become baggy. As one ages, less oxygen enters the capillaries and less carbon dioxide is removed, which makes breathing difficulties.

The function of the horizontal fissure of the left lung helps the constipated human to release any excess carbon from their body, meaning it is easier for them to defecate. Although in some cases of severe diarrhoea the mantelpiece of the left lung collapses into the pancreas distorting and disturbing the function of the horizontal fissure.

well one lung is lower than the other to make room for your heart.

expectoration

It has many balloon-like sacs that can hold air.

The tiny air pockets in the lungs can break down.

The blood vessels in the lungs can become clogged.

The outer lining of the lungs can stiffen.

Fluid can build up outside the lungs, reducing the capacity to expand.

Fluid can accumulate inside the lungs.

Foreign particles can accumulate in the lungs, preventing exchange of oxygen and and carbon dioxide.

Lung tissue can develop tumors.

I will assume you mean the organ that makes the left lung slightly smaller than the right and causes the apparent dent in the medial side. This organ is the heart. The reason the heart only causes the space in the left lung is that the left ventricle is far larger than the right and protrudes into the space where the lung would otherwise grow. This is the reason that people mistakenly think the heart is in the left of the chest. In reality it sits directly behind the sternum (very center of the thorax) and only the left ventricle sticks over to the left.

In radiology interpretations, this is terminology meaning that the soft tissue and bony thorax is normal. (Since there are normal age-related changes, the reading is customarily reported with this kind of phrase.)

The curability of cancer depends on various factors, including the type of cancer, the stage at which it is diagnosed, the overall health of the patient, and the availability of effective treatment options. While no cancer can be guaranteed to be completely curable in all cases, certain types of cancer have higher cure rates due to early detection, effective treatments, and favorable prognosis. Some of the more curable cancers include:

Testicular Cancer: Testicular cancer is highly curable, especially when detected early. The overall cure rate is over 95%, and even when the cancer has spread, treatment options are often successful.

Thyroid Cancer: The majority of thyroid cancers are well-differentiated and have a good prognosis. The five-year survival rate for most types of thyroid cancer is over 90%.

Melanoma: When detected and treated in its early stages, melanoma, a type of skin cancer, has a high cure rate. Surgical removal is often effective, and newer targeted therapies and immunotherapies have improved outcomes for advanced cases.

Hodgkin Lymphoma: Hodgkin lymphoma has a high cure rate, particularly in its early stages. Advances in chemotherapy, radiation therapy, and stem cell transplantation have contributed to improved survival rates.

Non-Hodgkin Lymphoma: Many types of non-Hodgkin lymphoma are curable, especially if diagnosed early. Treatment may involve chemotherapy, radiation, targeted therapies, or stem cell transplantation.

Cervical Cancer: Regular Pap smears and HPV vaccinations have led to earlier detection and higher cure rates for cervical cancer. In the early stages, surgery or radiation therapy can be curative.

Breast Cancer: Early detection through mammograms and advances in treatment have significantly improved the cure rate for breast cancer. Survival rates vary based on the stage at diagnosis.

Colorectal Cancer: When detected at an early stage, colorectal cancer is highly treatable. Surgery, combined with chemotherapy or radiation therapy, can lead to a good prognosis.

Prostate Cancer: Many cases of prostate cancer are slow-growing and localized. Treatment options such as surgery, radiation therapy, and hormone therapy can provide good outcomes.

It's important to note that advancements in cancer research and treatment are ongoing, and new therapies are continuously being developed. Additionally, individual responses to treatment can vary, and factors such as genetics, overall health, and the presence of other medical conditions can influence outcomes.

Early detection through regular screenings, maintaining a healthy lifestyle, and seeking medical advice for any unusual symptoms are key factors in improving the curability of cancer. If you or someone you know is concerned about cancer, it's important to consult with healthcare professionals for proper evaluation, diagnosis, and treatment planning.

Blood carried by the pulmonary arteries is deoxygenated. Blood carried by the pulmonary veins is oxygenated.

Diaphragm which is the most important muscle for breathing, separates lungs from abdomen

I could spout the usual list of cruciferous vegetables, beta glucan-rich mushrooms and immune stimulating herbs... but that would be a very short-sighted approach that ignores your body's need for complete nutrition. Your body evolved to thrive on unprocessed whole foods, ripe-picked and eaten with minimum cooking or freezing. This is the food that results in maximum cellular health. It's dangerous to think about specific foods that reduce the risk of cancer because of the human tendency to then eat them at the exclusion of other whole foods in favor of one or two. Your cells need a huge variety of macro and micro nutrients to sustain good health and this variety can only be obtained from a well balanced diet of whole foods. Healthy cells do not become cancerous. Focus on cellular health to achieve whole body health. Avoid mono-diets and reliance on a few specific foods to reduce cancer risk. There are no magic bullets.

No trachea is not the lung.

CN X (Vagus)

Oxygen levels go up while CO2 levels go down.

In the lungs, oxygen is absorbed into the blood while carbon dioxide is eliminated through exhaling.

You lungs will slowly clean themselves of tar, you breathing will improve and you may avoid getting smoking related diseases such as cancer.
