TECHNOLOGY BASICS: 1) What are the main components of an X-ray Tube? The x-ray tube consists of an electrode pair - a cathode and an anode. The cathode is a negatively charged heated filament made from tungsten. The anode is a positively charged flat disc‚ also made from tungsten. The electrode pair sits inside a glass vacuum tube‚ which is lined with lead for protection. 2) State the two interactions that occur in the X-ray tube to produce the x-ray beam Bermsstralhung interaction and Characteristic

Kidney Cancer KIdney Cancer is when cells in the body grow out of control. These cells can form a tumor or damaged tissue. If cancer cells grow in the kidney‚ it is called kidney cancer. The most common kidney cancer in adults is renal cell carcinoma. It forms in the lining of very small tubes in the kidney. Cancers found in the center of the kidney are known as transitional cell carcinoma. Wilms tumor is a kidney cancer that very young children can get. On average‚ people are diagnosed with kidney

SENSE- is the ability to perceive stimuli. SENSATION (PERCEPTION)- is the conscious awareness of stimuli received by sensory receptors. GENERAL SENSES- are those with receptors distributed over a large part of the body. SOMATIC SENSES- provides sensory information about the body and the environment. VISCERAL SENSES- are more specialized in structure and are localized to specific parts of the body such as pain and pressure. SPECIAL SENSES- are more specialized in structure such as smell

salt and water in the body as nephrons are located here to reabsorb water according to the demand of water needed by the body. The last layer is the pelvis. The major function of this renal pelvis is to act as a funnel for urine to flow until the ureter. A failed functioning kidney is very harmful for the organism. The organism may suffer and external medical assistance is required to keep the organism alive. Objective: To
