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

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

As we study and are learning about ALI and ARDS it seems people have a much longer survival rate than years ago. The technology‚ doctors and scientists have improved the outcome for people who have ADRS and ALI. We continue to make advancement

Surface Marking of the Lungs The apex of the lung extends upwards for one to two inches above the anterior extremity of the first rib‚ and is indicated by a curved line drawn from the upper border of the sterno-clavicular articulation to the junction of the inner and middle thirds of the clavicle‚ the highest part of the curve being from 1/2 inch to 1 1/2 inches above the clavicle. The apex of the right lung is 1/2 inch higher than that of the left. The subclavian artery lies on the cervical pleura covering

Each time a cigarette is smoked the detrimental chemicals pass through the airways to the lungs. A person may start with just a cough‚ but as time goes on they can come to develop asthma‚ COPD‚ emphysema‚ and then even cancer. When the lungs become irritated from the smoke‚ the cells that produce mucus will grow in quantity and size. This causes thicker and greater amounts of mucus in the lungs and airways. When there is an overproduction of mucus‚ your system has a hard time clearing it out. The
