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

puts a stop on the absorption of oxygen into the red blood cells. Carbon monoxide has different effects on people with different health conditions. Carbon monoxide also has different effects on different parts of the human body. Carbon monoxide‚ by displacing the oxygen from the red blood cells‚ deprives the brain‚ the heart‚ the nervous system‚ and many other vital organs of oxygen. The replacement of oxygen with carbon monoxide fills the red blood cell with carboxyhemoglobin (COHb). The lack of oxygen

iron in the center. It is the iron that binds the oxygen in a weak interaction that can easily broken. A RBC (red blood cell) is packed with haemoglobin molecules. The cell has no nucleus‚ so more haemoglobin molecules can be included. 2 Function of haemoglobin in Transporting Oxygen: * transport of O2 * transport of some CO2 from body cells to the lungs * conversion of CO2 to HCO3- by the action of the enzyme carbonic anhydrase in the RBC; HCO3- produces H+

sort of problem with its red blood cells (RBCs). If a person’s blood does not have the right amount of red blood cells or hemoglobin‚ anemia can develop. Anemia is defined as a decrease in the circulating red blood cell mass and an equal decrease in the oxygen carrying capacity of the blood (also known as hemoglobin). There are many types of anemia that are grouped by their underlying cause. To determine which type‚ doctors describe color‚ size‚ and shape of red blood cells. Treating it has to be specific

homeostasis about 2.5 million of those erythrocytes are destroyed and replace every second. The life cycle of an erythrocyte is 120 days. In the short lifetime the erythrocytes make an astonishing 75000 round trips between the lungs‚ heart and cells of the body. Erythrocytes do not possess a nucleus they are unable to repair or synthesize new cellular components and eventually they wear out. When they wear out most aging erythrocytes are pulled out of circulation by specialized leukocytes called

The use of banned performance-enhancing drugs (PEDS) in sports is commonly referred to as doping. The word doping is probably derived from the Dutch word dop‚ the name of an alcoholic beverage made of grape skins used by Zulu warriors in order to enhance their prowess in battle. The term became current around the turn of the 20th century‚ originally referring to illegal drugging of racehorses. ‘Doping’ however is as old as competitive sport itself. Modern times - In 1904 Olympics

questions The healthcare provider should initially obtain a history of any previous anemia or blood disorders and records‚ if possible‚ providing results of any previous blood tests as these can help determine the duration of the disorder. It will be important to examine any family medical history‚ particularly questioning about jaundice‚ cholelithiasis‚ splenectomy‚ bleeding disorders‚ and abnormal blood test results (Maakaron‚ 2011).

Definition of Hemoglobin • Description of Hemoglobin • Questions To Ask Your Doctor About Hemoglobin Definition of Hemoglobin Hemoglobin is the iron-carrying protein found in red blood cells that binds to oxygen. Description of Hemoglobin Hemoglobin is a crystallizable‚ conjugated protein consisting of an iron-containing pigment (called heme or hematin) and a simple protein‚ globin. In the lungs‚ it combines readily with oxygen to form a loose‚ unstable compound called oxyhemoglobin
