The Anatomy Of The Lungs - 926 Words

Small Cell Lung Cancer (SCLC), also known as oat cell cancer, is a serious disease that accounts for 10-15% of all lung cancers. It is predominantly caused by consistent exposure to tobacco smoke. It differs itself by its unique histology and aggressive metasteses. Patients who are diagnosed with this particular ailment usually end up dying within a short time frame after diagnosis. This paper is going to evaluate the gross anatomy of the lungs, proposed mechanisms of SCLC development, histological features, diagnosis and current therapies that are being used for treatment. The anatomy of the lung is quite complex, but if we follow the direction of the airflow, it will be easy to understand where the developments of most lung cancers arise. Air passes in a unique pathway as it enters into the lungs. It goes from the nasal or oral cavity to the pharynx, through the larynx, trachea, into the right and left main stem bronchi. The lungs then further divide into the terminal bronch ioles where they branch further to the functional unit of the lung, the alveoli. The alveoli are where oxygen and carbon dioxide gas exchange occurs and they consist of several distinct cells. Type I cells are the endothelial cells that make up the alveolar wall. Type II cells are responsible for production of pulmonary surfactant. Type III cells are the alveolar macrophages that aid in immune response and clearance of small particles. Lung cancers typically develop in the cells lining theShow MoreRelatedThe Anatomy Of The Lungs1366 Words   |  6 PagesCancer of the lungs takes more lives every year than breast, colon, and prostate cancer combined. In order to prevent these statistics from happening, Low-dose Computed Tomography Scans (LDCT Scans) can be used to prevent the cancer cells from spreading. Medicare and Medicaid are willing to pay for such screenings for those who are 55-77 years of age and who have smoked a pack of cigarettes a day for over 30 years or those who a re smoking currently within that age group. The cost for such screeningsRead MoreAnatomy Carcinoma Of Lung / Skull Metastasis1226 Words   |  5 Pages Case Study-Anatomy-Carcinoma of lung w/ skull metastasis Abstract Squamous cell carcinoma represents 30% of all lung carcinomas. A carcinomas is cancer that appears in the epithelial tissue. Epithelial tissue is mostly found in the lining of your organs, like the esophagus. Squamous cell carcinoma, or SqCc for short, is known to produce malignant tumours in the brain parenchyma. There has been a case of SqCc that has impacted the parietal bone. An 80 year old Australian man was admitted with aRead MoreDescribe the Gross Anatomy of the Lungs; and Define Pneumonia and Outline Briefly the Etiology, Pathophysiology and Radiographic Appearances of Alveolar Pneumonia.1886 Words   |  8 PagesDescribe the gross anatomy of the lungs; And define pneumonia and outline briefly the etiology, pathophysiology and radiographic appearances of alveolar pneumonia. 1. Introduction The lungs are the essential organs of respiration; they are two in number and are placed one on either side within the thorax, separated from each other by the heart. The substance of the lung is light, spongy and porous. The surface is smooth, shining and marked into numerous areas, indicating the lobules of the organsRead MoreFetal Pig And The Human Being s Anatomy1225 Words   |  5 Pages Hypothesis Due to the fact that the fetal pig and the human being’s anatomy are extremely similar, with the exception of a few minor parts, the fetal pig will be a precise tool in learning about the anatomy of a human. Introduction In courses such as biology, anatomy, and physiology, learning the anatomy of a human is imperative to learning about its functions and processes. Due to a lack of money, resources, and access, UConn cannot provide the use of a human cadaver for educational purposesRead MoreThe Fetal Pig And Human Anatomy1664 Words   |  7 Pages Hypothesis I believe if we observe a fetal pig specimen, it will serve as a very helpful comparative tool in learning human anatomy because much of the fetal pig’s organ systems are very similar in anatomy and physiology to that of the human, as the pig and human are both mammals. From the fetal pig, we can gain an understanding of organ size, the relation between organ systems and how they function together as a whole. Introduction Pigs are one of the most similar animals to humans, and canRead MoreDescribe How The Design Of Respiratory System Facilitates Gas Exchange?1099 Words   |  5 Pageslevel. This process is carried out through a complex system called Respiratory System. Organs which comprise respiratory system include mouth, nasal passage, glottis, trachea, larynx, pharynx, bronchi, bronchioles, alveoli and last but not the least lungs. In the following lines, we’ll discuss in details how the structures of respiratory system accomplish exchange of gases. The upper respiratory tract comprises those organs that bring the air in and lower respiratory tract comprises those parts thatRead MoreEssay on White Rat Dissection Lab Report1003 Words   |  5 PagesWhite Rat Dissection Lab Report GOALS: Learn about the anatomy of the White Rat.

The heart acts a twofold, self-modifying suction and pressure pump, the parts of which work in union to push blood to all parts of the body. The right half of the heart (right heart) gets ineffectively oxygenated (venous) bloodRead MoreThe Respiratory System And The Effect Of Exercise1376 Words   |  6 Pagesrespiratory system is composed of the nose, mouth, pharynx, larynx, lungs, bronchi, bronchioles, alveoli, the diaphragm and intercostal muscle. This can be separated in three main parts which are the airways, the lungs, and the muscle of respiration (InnerBody.com, 2015). The airways are composed of the nose mouth, pharynx, larynx, bronchi and bronchioles. They conduct the air full of O2 or CO2 between the outside and the lungs. The airways are formed a main external cavity, the nose, that connectsRead MoreThe Human Body is An Example of Amazing Efficiency Essay588 Words   |  3 Pagesare certain laws and forces that are the reason behind the human body can function as efficiently as it does. Gas laws help us understand certain aspects of human anatomy such as pressure. Laplace’s Law is one gas law that helps explain distending pressures within the body.
