Lung cancer is a disease characterized by uncontrolled cell growth in tissues of the lung. If left untreated‚ this growth can spread beyond the lung in a process called metastasis into nearby tissue and‚ eventually‚ into other parts of the body. Most cancers that start in lung‚ known as primary lung cancers‚ are carcinomas that derive from epithelial cells. The main types of lung cancer are small-cell lung carcinoma (SCLC)‚ also called oat cell cancer‚ and non-small-cell lung carcinoma (NSCLC). The

At the start of his essay‚ Twain asserts that humans did not ascend from lower animals‚ but rather descended from higher animals. He explains that he came to this conclusion after conducting scientific experiments that compared the nature of humans and animals.

Similarly‚ some people have more money that they would ever need but still desire more

the four lobes of the brain and its functions. The frontal lobe has to deal with personality‚ behavior‚ and emotions. We use this lobe to make judgments‚ plan and solve problems. We use the frontal lobe to also speak‚ write and control body movement. The next lobe is the parietal lobe. It deals with interpreting language‚ words as well as signals from vision‚ hearing‚ motor‚ sensory and memory. The occipital lobe interprets vision like color‚ light‚ and movement. Finally‚ the temporal lobe is used

a) As the veins are responsible for returning deoxygenated blood to the heart‚ they are most often working against gravity. The blood is prevented from reversing direction through large venous valves. However‚ if the pressure applied downwards on these valves is great enough and applied for a significant period of time‚ such in the case of prolonged periods of standing‚ the edges of the veins can become distended and eventually prevent the edges of the valves from successfully sealing. Varicosities

Lower class Americans do not often discuss the class separation that exists in today’s society‚ but we all know there is something going on.

Frontal Lobe The outer layer of our forebrain consists of the cerebral cortex. The cerebral cortex is so significant since it controls our ability to learn and store complex and abstract information. Also‚ it is our control and information processing center. The cerebral cortex consists of many interconnected neurons that are quite useful. The cerebral cortex covers the frontal lobe. This lobe is so important because it controls our organization‚ planning‚ and creative thinking. The frontal lobe is also

In “Winter‚ Frontal Lobe” by Brecken Hanock‚ the speaker has two meanings that are simultaneously occurring‚ a literal and a metaphorical (which can be supported by the Winter and frontal lobe of the title).

A varicose vein is a superficial vein with a faulty valve. The calf muscles squeezes the deep veins in the leg and pressure is reduced in the superficial veins. These superficial veins are fitted with special one-way valves to prevent the blood running backwards. The weight of blood in the vein is conciderable especially while standing still and the blood flow is against gravity. and blood is allowed to pool stretching the walls of the veins which damage the valves resulting in the lumen being unable
