The working of the lungs is vital to the human physical structure. They provide the body with oxygen to keep the cells happy and help to maintain homeostasis. There are many carcinogens that cause cancer leading to the lungs not to doing their job. Sometimes the cancer spreads and causes metastases. The patient’s medical diagnosis is malignant neoplasm of the bronchus and lung brain metastases.
The lungs are two large sacs within the human body that optimize gas exchange between the air breathed and the blood. (Lung cancer, 2013) The lungs take in oxygen and release carbon dioxide. The lungs are made of spongy tissue, which allows for expansion and contraction. The lungs occupy most of the thoracic cavity. Because of the location of the heart the right lung is slightly larger than the left lung. The base of the lungs sits on the diaphragm allowing the diaphragm to help with breathing.
When breathing occurs, air enter through the mouth or/and nose and passes through the pharynx, larynx, and trachea. At this point in the body, the trachea splits off into the right and left bronchi....

    When you breathe in, air containing carbon dioxide (CO2) and oxygen (O2) it moves down your trachea; a tunnel containing cartilage and smooth tissue. Air then travels through two hollow tubes called bronchi; narrow branches lined with smooth muscle, mucosal and ringed cartilage to support the structure. The bronchi divide out into smaller tunnels called bronchioles; are small branches 0.5-1mm, lined with muscular walls to help dilate and constrict the airway. At the end of the bronchioles are little air sacs called alveoli; which assist in gas exchange of O2 and CO2. (Eldridge, 2016) Towards the end of alveoli are small blood vessel capillaries. O2 is moved through the blood stream through theses small blood vessels (capillaries) at the end of the alveoli and the CO2 is then exhaled. (RolandMedically,

    Healthy lung tissue is predominately soft, elastic connective tissue, designed to slide easily over the thorax with each breath. The lungs are covered with visceral pleura which glide fluidly over the parietal pleura of the thoracic cavity thanks to the serous secretion of pleural fluid (Marieb, 2006, p. 430). During inhalation, the lungs expand with air, similar to filling a balloon. The pliable latex of the balloon allows it to expand, just as the pliability of lungs and their components allows for expansion. During exhalation, the volume of air decrease causing a deflation, similar to letting air out of the balloon. However, unlike a balloon, the paired lungs are not filled with empty spaces; the bronchi enter the lungs and subdivide progressively smaller into bronchioles, a network of conducting passageways leading to the alveoli (Marieb, 2006, p. 433). Alveoli are small air sacs in the respiratory zone. The respiratory zone also consists of bronchioles and alveolar ducts, and is responsible for the exchange of oxygen and carbon dioxide (Marieb, 2006, p. 433).

    Whether lung cancer is operable or not, may well depend upon the circumstances of the patient involved; however, where certain factors do not allow for this option, other treatments may well be offered. Many factors must be taken into consideration before any treatment or operation can take place, as either may have a prominent bearing on the prognosis of the cancer patient.

    Cancer of the lung was nearly nonexistent in the early 1900’s. By the middle of the 20th century an epidemic became apparent throughout the United States and the rest of the world. It is primarily correlated with the widespread abundance of cigarette smoking in the world. The tobacco industry has multiplied its production immediately prior to World War I. There was a typical 20 to 30 year lagging period between the initiation of cigarette smoking and the actual tumor formation in the lungs. Lung cancer is the cancer that originates in the tissues of the lungs. It occurs when cells in the lung start to grow rapidly in an uncontrolled manner. Lung cancer can start anywhere in the lungs and affect any part of the respiratory system. Most of all lung cancer cases start in the lining of the bronchi (health-cares.net, 2005). It is the leading cause of all cancer deaths in the world. During this time the tobacco companies would continue to say that cigarette smoking was not addictive and did not cause any type of cancer. Even with all evidence in the world today about tobacco causing cancer, Tobacco companies still remain the most profitable business in the world. Lung cancer is very common in both women and men. Women account for about 40 percent of the lung cancer cases in the world. Women who smoke are more than twice as likely to develop lung cancer as those of men who smoke (Tavor, 2005).

    The larynx prevents food and liquids from traveling down the air path ways which could result in choking. From the larynx, Bronchi trachea splits into two bronchi each leading to a lung, each lung is divided into lobes. The right lung has three lobes and the left has two lobes. The right lung is slightly larger than the left lung. The two lungs are mainly made of up connective tissue, which gives them their soft and spongy texture. The bronchi branch are smaller and are called bronchioles which are divided many more times in the lungs. The lungs is made up of connective tissue, blood, lymphatic tissue, air pathways and alveoli are at the end of the branches inside of the lungs. The alveoli sends oxygen and removes carbon dioxide. This is a basic view of how the respiratory system functions and if the respiratory system doesn’t do its job then this could lead to infectious diseases of the respiratory

    In this essay I am going to talk about the lungs and the stages of their embryonic development. I chose the lungs because they are one of the most important organs for survival -they supply oxygen to cells and release carbon dioxide to the atmosphere. This essay will mostly focus on the different stages of the lung development- the embryonic, the pseudoglandular, the canalicular, the terminal sac, and the postnatal stage.

    The airway includes the nose, mouth, pharynx, larynx, trachea, bronchi, and bronchioles. It carries air between the lungs and the outside elements that surround the body. The lungs are the functional units of the respiratory system and they act as such. They pass oxygen into the body and remove carbon dioxide from the body. Then there are the muscles of respiration. These muscles include the diaphragm and intercostal muscles. They work simultaneously as a pump, pushing air into and out of the lungs during breathing.

    Diagnosed with lung cancer, now what!? Time to do some research. Lung cancer is the number one cause of deaths in males and females. The causes, diagnosis, and treatment of lung cancer have advanced recently with new technology available to scientists and the medical profession. Lung cancer develops when the cells grow abnormally and tumors form instead of healthy lung tissue. It can take place in one or both lungs, normally the cells that line the air passages. Not all tumors are cancerous, the ones that do not spread are benign tumors. The more tumors that develop in the lungs will cause the lungs to work less efficiently. The metastatic tumors spread to other parts of the body passing through the blood stream or lymphatic system.

  • Lung Cancer Speech

    880 Words  | 2 Pages

    According to “Medical News Today” cancer is a disease that is caused by an over growth of anomalous cells on one or more lungs. Cells often go up the air pipes which can cause difficulty to breath. Due to the over production of cells the tissue cells often begin to over produce; which results in tumors. There are two types of tumors: malignant and benign. Malignant tumors are the more dangerous of the two due to its invasive nature; which makes it cancerous. While benign is not invasive in other words non-cancerous. This is why cancer spreads to multiple areas and can be sometimes very difficult to fight. Cancer cells are abnormal not only because of their evasive nature, but also because of its irregular life cycle. Rather than expire like a regular cell, they continuously grow and duplicate which causes the disease to spread. This makes cell abnormal in shape and other qualities; known as a sickle cell. Due to the large growth and reproduction rate of the cells this makes the spreading of the cancer more rapid. Each cancer has specific symptom, for lung cancer the sympto...

    Every cell in the human body requires oxygen to function, and the lungs make that oxygen available. With every breath we take, air travels to the lungs through a series of tubes and airways. After passing through the mouth and throat, air moves through the larynx, commonly known as the voice box, and then through the trachea, or windpipe. The trachea divides into two branches, called the right bronchus and the left bronchus, that connect directly to the lungs. Air continues through the bronchi, which divide into smaller and smaller air passages in the lungs, called bronchioles. The bronchioles end in clusters of tiny air sacs, called alveoli, which are surrounded by tiny, thin-walled blood vessels called capillaries.

Lung cancer is detrimental to the Respiratory System and can cause permanent damage. Lung cancer is a tumor that grows in your lungs and it can also spread to other parts of your body. Early stages of lung cancer are hard to detect because it could take about a year for the tumor to grow to the point when you start experiencing symptoms. The most common cause of lung cancer is smoking cigarettes and other tobacco products. There are other causes like secondhand smoke, asbestos, and lung cancer is common in your family.Lung cancer has different risk factors, symptoms,

  • The Mechanism and Regulation of Breathing

    While this is happening diaphragm muscles contract and push down towards the abdomen. The lungs are made to expand because the pleural surfaces of the lungs are attached to the pleural on the chest wall; this increases the volume. of the air spaces and drops the air pressure in the lungs so that air rushes in. Expiration is mainly an involuntary reaction to the external intercostals and diaphragm muscles relax. The elastic fibres in the stretched lung are recoiled which allows the ribs and diaphragm to return to their original position.

  • The Structure Of A Lung Transplant And The Respiratory System

    The trachea filters the air we breathe. At the end of the Trachea it splits into two which is called Bronchus. Bronchus are two air tubes that branch off to the Trachea and carry air directly into the lungs. The lungs are the main organ in the respiratory system. In the lungs, oxygen is taken into the body and carbon dioxide is breathed out. The red blood cells collect oxygen from the lungs and deliver it to other cells in our body and they also pick up the waste from the other cells (Carbon Dioxide) and bring it back to the lungs to get exhaled. The diaphragm is not part of where the air travels, but it is used to air in and out of the lungs. The diaphragm is a muscle that moves, causing a change in air pressure. When you breathe out, the diaphragm moves upward, which decreases the volume of the lungs, causing high pressure. When you breathe in, the diaphragm moves downwards in it can increase the volume of the lungs which causes negating pressure. These organs are equally useful as they all play a role to keep your respiratory system working. You need to
