Lungs

It is usually warmer, but not always. The temperature of the interior of your body is about 98-99 degrees Fahrenheit. So when you breathe in air that's cooler than that, the air is warmed by your lungs, and so it's warmer when it comes out. However, if the air you're breathing in is hotter than your body temperature, like say 105 degrees in the desert, the air will actually be cooled by your lungs, and will come out cooler than when it went in.

Smoking really but also it's dead tissue that'll go away eventually. But go to the hospital

Cathy is right about no rainforest producing half of the world's oxygen, but she is absolutely wrong about plants not providing a significant amount of oxygen. The truth is that 98% of the world's atmospheric oxygen comes from plant life. Half of that 98% comes from phytoplankton in the oceans. The other half comes from plant-life on the surface. So, no individual rain forest can account for anywhere near half of the oxygen. In fact, it is now believed that rain forests are oxygen neutral meaning they use as much as they produce (after all, there are innumerable species and animals in the rain forest).

I don't believe that any rainforest produces anywhere near that amount of oxygen. I am terrible with names, but I had the opportunity to ask a very highly acclaimed and reputable scientist about oxygen-making plants, leaves, etc. His response got my attention. He said that plants do not provide a significant amount of oxygen, and rainforests do not provide a significant amount of oxygen. He said it is a myth that they produce anywhere near a significant amount of oxygen. Probably perpetuated by someone who is trying to save a rainforest, and they are trying to think up reasons why we should think they are valuable and worth saving.

I happen to be a person who loves forests of all kinds, and who wants to see forests instead of shopping malls! However, I love the truth. Very likely the truth about the rainforests is that their greatest value is to provide habitat for marvelous animals and plants. I also believe that people have not fully explored the possibilities inside a rainforest. There are probably new species and varieties of plants, animals, birds, insects, etc. that may potentially be valuable to us.

I believe that a rainforest has a great deal of value to us as the rainforest it is. I don't believe it has much value as a source of oxygen for human beings. But there are so many other great values contained inside the rainforest that I see no reason to try to make up things about it!

Forests are full of trees, and for animal and human respiration, trees are important. Plants and trees use carbon dioxide in the process of photosynthesis, the waste output being oxygen, which then supplies animals and humans with oxygen to breathe. Trees contribute towards providing breathable air for all animal species, therefore they are called the lungs of the earth.

Because most of the Amazon Rainforest is within its borders, and the Amazon Rainforest prduces most of the oxygen we use to breathe.

All the way to the deepest depth 11,110 meters.

Medical professionals can do this by injecting a radioactive isotope into the bloodstream and follow it's progress using imaging equipment (MRI for eg).

I can't think of way to do this at home.

If you wanted to check the blood supply to your foot, press your toe with your finger, once you have moved your finger, the area should look white briefly then go back to a pinky colour similar to the rest of your foot fairly quickly.

The lungs hold air that is breathed in. Oxygen gas in the air moves into the blood. The heart pumps to transports this oxygenated blood to cells in the body that need it to produce energy.

Factors such as gender, physical fitness, age, height, and weight can all affect lung capacity. This page offers an explanation on how they affect it: http://www.madsci.org/posts/archives/2003-04/1050155434.An.r.html

the pulmonary system.

The motto of American Lung Association is 'It's a matter of life and breath.'.

You have pulmonary aorta that arises from the right ventricle. It splits into right and left branches. The branches most probably continue to divide with the bronchi. Ultimately you have the network of the capillaries to cover the alveoli.

The descending aorta is divided into two portions, the thoracic and abdominal, in correspondence with the two great cavities of the trunk in which it is situated.

The descending thoracic aorta is located in posterior mediastinum.

Blood flows through the walls of the lungs to release carbon dioxide and to absorb oxygen for distribution throughout the body.

yes they have one heart that runs through a large part of it's body

Human brain, computer can only be programmed to perform the brain can think for itself and be trained to be faster than any computer. It was somebodys brain that invented the computer so it's quite obvious really, not to mention the only reason numbers exist is because we thought them up and the computer cannot do the things that human can do!!!

this is the thoracic cavity, the space between the neck and the abdomen, this contains the lungs, heart & the main artery called the aorta, the lungs are covered by a membrane called the pleura which holds the lungs in situ and is the area affected by pleurisy, if air or gasses are allowed to permeate this area outside the lungs the vacuum that enables breathing is compromised and a collapsed lung can occur.

Your lungs do not hold the heart. Heart is placed in the mediastinum between both the lungs. Two third part of the heart is on the left side of plane that passes from mid-line. So heart has more impression on the left lung as compared to right lung.

Blood comes into your heart through the veins all throughout the body, it enters the heart through the superior and inferior vena cava, leaves the heart though the pulmonary artery, enters the lungs, gets oxygen, enters the heart again through the pulmonary veins, and then leaves the heart and goes back throughout the body through the aorta.

So blood travels from the heart, to the lungs, back to the heart, than out the heart and all through the body.

The alveoli transports oxygen from the lungs into the circulatory system.

Another Answer: They work together by inhaling and exhaling . The heart pumps blood into the lungs where the blood is oxygenated. The blood is then returned to the heart and the newly oxygenated blood is circulated to the rest of the body. The respiratory system performs a process known as gas exchange that releases carbon dioxide from the body and brings in oxygen. This occurs in the lungs and the circulatory system then transports the oxygen to tissues that used internal respiration to burn fuel in the form of ATP (adenosine triphosphate) for energy, thus creating more carbon dioxide.

More to the Answer You breathe in oxygen into your lungs. The oxygen diffuses across the thin walls of the alveoli in the lungs and the thin walls of the blood vessels in the lungs into the blood stream. Here it attaches to the hemoglobin molecules inside red blood cells. The red blood cells are carried by the blood vessels to all parts of the body. The hemoglobin releases oxygen in the periphery, and picks up carbon dioxide (CO2). The CO2 attached to the hemoglobin molecules in the red blood cells is then transported to the lungs, where it diffuses across the walls into the alveoli, and is breathed out.

Additional Information The heart pumps blood into the lungs where the blood is oxygenated. The blood is then returned to the heart and the newly oxygenated blood is circulated to the rest of the body.

The respiratory system performs a process known as gas exchange that releases carbon dioxide from the body and brings in oxygen. This occurs in the lungs and the circulatory system then transports the oxygen to tissues that used internal respiration to burn fuel in the form of ATP (adenosine triphosphate) for energy, thus creating more carbon dioxide.

They work hand in hand to provide the tissues of the body with oxygen. The respiratory system oxygenates the blood and the circulatory system sends it to the rest of the body.

Lung cancer itself typically doesn't directly affect hearing in the same way that it can impact the respiratory system. However, certain factors associated with lung cancer and its treatments could indirectly affect hearing:

Chemotherapy: Some chemotherapy drugs used to treat lung cancer can have side effects on the nervous system, including the nerves responsible for hearing. This could potentially lead to hearing changes or issues.

Medications: Certain medications prescribed for pain management, symptom control, or to manage side effects of treatment might have auditory effects as a side effect.

Infections and Complications: Lung cancer and its treatments can weaken the immune system, making individuals more susceptible to infections. In some cases, infections that affect the ears or the auditory system might occur.

Surgery: If surgery is required as part of lung cancer treatment, there could be a risk of damage to nearby nerves that are involved in hearing, although this is relatively rare.

Overall Health: The general decline in health associated with advanced lung cancer or aggressive treatments could indirectly affect various bodily systems, potentially including hearing.

It's important to note that any changes in hearing should be evaluated by a medical professional. If you or someone you know is experiencing changes in hearing while undergoing lung cancer treatment, it's advisable to discuss these symptoms with a healthcare provider. They can assess whether the changes are related to lung cancer, its treatments, or other factors and provide appropriate guidance and care.

The purpose of the lung is to provide a large surface area in a conveniently folded up form, where gas exchange can take place efficiently, allowing oxygen to enter the body and carbon dioxide to leave.

gaseous exchange takes place when the volume of the chest cavity is increased or decreased.
