HEART-LUNG MACHINE eng. Hassanain Ali Lefta Mossa * ‚ HasAli76@yahoo.com During an open-heart surgery (such as valve surgery)‚ an extracorporeal (i.e. outside the body) equipment called the heart-lung machine takes over the functions of the heart and lungs‚ so that the heart can be carefully stopped while the vital organs continue to receive blood and oxygen. The surgeon can then operate in a blood-free surgical field without interference from bleeding or the heart’s pumping motion. The principle

Measuring of Lung Capacity Introduction This lab report is over the functions of the lungs and a better understanding of how the respiratory function happens within your body. You will be measuring the amount of air you breathe in and out. This function is called tidal volume‚ which is about 500 cc of air. Second portion of the testing procedure will be determining the amount of vital capacity or maximum amount your lungs can expel. You will be working in pairs with a lab partner and take turns recording

the cancer century. This is because more than a hundred types of cancer have been discovered in this century‚ and secondly‚ because enormous medical efforts were made to fight all kinds of cancers all over the world. In the early decades of the century‚ cancer was considered to be a fatal disease‚ and although many cancers remain fatal‚ medical therapy has developed significantly over the years such that most cancers can be treated and cured. After decades of struggling with various cancers‚ doctors

Radiation therapy uses high-energy radiation to shrink tumors and kill cancer cells. X-rays‚ gamma rays‚ and charged particles are types of radiation used for cancer treatment. The radiation may be delivered by a machine outside the body called a linear accelerator to focus x-rays directly on the tumor or tumor bed (external-beam radiation therapy)‚ or it may come from radioactive material placed in the body near cancer cells (internal radiation therapy‚ also called brachytherapy). Systemic

Health April 14‚ 2013 CVD and Cancer After taking the cancer and CVD risk assessment I learned that aside from working in the sun without protection‚ smoking is my largest risk for cancer or CVD. Aside from these two risk factors I live a fairly healthy life‚ I work harder than most people my age can even fathom from their deep-fryer station at McDonald’s‚ I eat fairly well and I seldom find myself stationary. My top-dog risk factor as determined by the cancer and CVD risk factor assessment

Breast cancer detection for the prevention and treatment Director of molecular diagnostics‚ Tianjin Cancer Hospital Center in JinPu said‚ genetic testing is through the blood‚ other body fluids or tumor tissue for gene sequences were detected and analyzed. Currently‚ breast cancer topped the incidence of female cancer‚ and lung cancer is the first cancer mortality rates for men and women‚ the incidence increased year by year‚ and getting younger and younger.

Determining lung capacity Experiment: This is the experiment of determining lung capacity. All the students in the group measured three types of different parameters: vital capacity‚ expiratory reserve and tidal volume. “Lung volumeizing refer to physical differences in lung volume‚ while lung capacities represent different combinations of lung volumes‚ usually in relation to inhalation and exhalation.The average pair of human lungs can hold about 6 liters of air‚ but only a small amount of
Premium Respiratory physiology Lung
How lungs Work Your lungs are part of a group of organs and tissues that all work together to help you breathe. This system is called the respiratory system. The main job of the respiratory system is to move fresh air into and get waste gases out of the body. Lungs are very important because Oxygen‚ a basic gas‚ is needed by every cell in your body in order to live. The air that comes into the body through the lungs contains oxygen and other gases. In the lungs‚ the

How are they alike‚ and different? Is one more efficient than another? Gills/Lungs?HumansIn humans air travels into the mouth‚ or nose‚ and into the nasal cavity‚ followed by pharynx. The pharynx is where food and air cross paths. The pharynx increases the chance of choking‚ but also allows breathing when exercising and respiration though the mouth‚ if the nose is closed. Next‚ epiglottis opens allowing air to move into the glottis‚ and pass the larynx (voice box). After this air makes its way into
