THE GENITOURINARY SYSTEM

THE GENITOURINARY SYSTEM

EVERY BODY cell not only must build its substance and obtain its energy from nutrients supplied in the food you eat; it must get rid of wastes. And all cells deliver their waste products continuously to the blood. In turn, the blood carries them to various centers for excretion. 

Thus, carbon dioxide and some water in the form of vapor are removed from the blood in the lungs. Salts and additional water pour out through the skin's sweat glands. Other wastes, including water, salt, urea, and uric acid-leave the blood in the kidneys. Blood enters the kidneys through the renal arteries and leaves through the renal veins and, in circulating within the two kidneys, goes through a fabulous filtering system. 

The kidneys-each about 4-1/2" long, 2-1/2" wide, 1-1/2" thick, and weighing 5 ounces-are located deep in the abdomen at about the level of the lowest ("floating") ribs. Essentially, they are filters containing intricate plumbing-a system of tiny tubes called nephrons whose combined length in each kidney is about 140 miles. To the naked eye, a single nephron would resemble a grain of sand. Under a microscope, it has the look of a twisted worm with a huge head. The head, called the glomerulus, is covered with a network of capillaries that carry blood continuously into the glomerulus. 

The tail is the tubule. In a healthy kidney, as blood enters a glomerulus, a fluid is separated from it. The fluid contains neither red, nor white blood cells nor only a trace of large protein molecules. The fluid passes along the tubule, and about 99 percent of the water, amino acids, proteins, glucose, and minerals needed by the body are returned to the bloodstream. The remaining fluid, with its content of waste materials, is eliminated from the body as urine. Every 24 hours, the kidneys filter about 200 quarts of fluid and salts.

One or two quarts of the waste go to the bladder and are flushed out of the body. Actually, the kidneys have a tremendous reserve capacity; they could clean nine times more fluid than they are called upon to do, and for this reason one healthy kidney can readily serve the body's needs. The kidneys function to maintain the correct balance between the salts and water of the body, to get rid of any toxic substances, and to keep the body in correct mineral balance. For example, too much potassium in the blood could stop the heart quite as effectively as a bullet. 

EXERCISES FOR ABDOMEN, BACK, AND BUTTOCKS

EXERCISES FOR ABDOMEN, BACK, AND BUTTOCKS

Exercise 1 for muscles of lower abdomen: Lying flat on the floor, exhale, then raise one leg slowly without bending; hold it up at about a 45- degree angle while counting to 10 (about 10 seconds); lower it slowly; inhale, repeat with the other leg. 

To strengthen the muscles without straining them, begin by repeating the exercise 2 or 3 times, and increase gradually until you can repeat about 20 times without straining.

Note: Exhaling helps to protect the diaphragm from the pressure generated by borne exercises.

Exercise 2 for muscles of upper abdomen: Lying flat on the floor, with arms folded over chest, raise head and shoulders slowly on the floor; hold for about 10 seconds; relax and inhale, As muscles grow stronger, increase gradually to or muscles of buttocks: While lying flat, tighten the buttocks as much as possible; hold for about 10 seconds before relaxing. 

Repeat 2 or 3 times and increase gradually to about 20 times. Exercise 4 for muscles of back: Lying on your stomach, keep arms at sides and legs on the floor, and slowly raise chest and shoulders. Hold for about 10 seconds. Lower slowly. Increase gradually from 2 or 3 times to about 20 times.

Symptoms of Cancer - How to detect Cancer? Answer these questions

CANCER SIGNALS

Some signs and symptoms are commonly associated with cancer. They include: Any lump or thickening in the breast or elsewhere Any sore that does not heal Any persistent change in bowel or bladder habits Persistenthoarseness or coughing Persistent indigestion or difficulty in swallowing Any change in a wart or mole Any sudden weight loss Actually, none of the foregoing constitutes proof of cancer-only that cancer is a possibility which should be investigated without delay.

No sign or symptom-either severe or mild but persistent or recurring -should be neglected, it bears repeating here, on the grounds that it may not mean anything or that the doctor may say it's "just nerves." The preventively minded physician whom you see regularly for your checkups will welcome being consulted about such signals, will not pass them off lightly as "just nerves," will check thoroughly, and, if it should be just a matter of "nerves," will help you do something about the "nerves.

YOUR OWN HEALTH INVENTORY

In addition to regular periodic checkups by your physician and your alertness for danger signals, there is an additional line of defense, an extra safeguard, you can put to use in maintaining health. It consists of a simple inventory of your health, a checklist of statements. Taking the inventory at home will require only a few minutes once a month.

Mark your calendar now to remind you to refer to this chapter and the following statements on some convenient date each month, perhaps the first or fifteenth. If you cannot say "True" to anyone of the statements that follow, you should see your doctor as soon as possible. If you have a perfect "True" score, it is quite likely that your health is being maintained satisfactorily, and you need not see your physician again until your next scheduled examination.

1.            I have noticed no sore on skin, lips, or tongue that doesn't seem to heal.

2.            I am not aware of shortness of breath when walking on level ground or when performing any type of activity that never before made me short of breath.

3.            I am not bothered by indigestion, nausea, appetite loss, abdominal pain or cramps, or the recent sudden appearance of constipation or diarrhea.

4.            I have noticed no blood in bowel movements or urine.

 5.           I am not steadily losing or gaining weight and I am satisfied that my weight is suitable for me.

6.            I do not feel myself becoming nervous, irritable, or depressed. I have had no crying spells and no feelings of overwhelming sadness, worthlessness, mental apathy. I have no persistent feeling that any- body is against me. I do not feel a nervous breakdown coming on.

7.            I do not feel unduly fatigued after little effort, mental or physical. I have no feeling of being rundown.

23.          I do not believe that I may have picked up some disease overseas during the war which may now be coming to the surface.

Important Note: If you cannot say "True" to one or more of the preceding statements, it does not necessarily mean that you have a serious problem. There may, indeed, be a clue to something serious-and because it is likely to be an early clue, the problem is very likely to be amenable to effective treatment. On the other hand, the problem may be mild, possibly even temporary. But let your physician make the diagnosis for you. He will almost certainly agree that it is good preventive medicine, in the best interests of your continued good health, for him to check up on the lead provided when you cannot say "True" to a statement. – 

How Blood tests helps in finding Urinary problems

Today there are sensitive blood tests for this; they measure the amounts in the blood of certain chemicals, called enzymes, released when the heart is damaged. Urine tests are helpful in detecting kidney disease and other urinary tract disorders and may provide clues to problems elsewhere in the body, such as diabetes. Today, radioactive isotope scanning is a sophisticated and vast new area of testing, useful for the detection of disorders in many different organs. Such scanning is based on the fact that certain chemical elements tend to be deposited in specific organs, and these elements can be made slightly and briefly radioactive; then their distribution in the body can be established with scanning instruments that can pick up their radio-activity and record it on film or paper.

Abnormalities become visible as areas of increased or decreased radioactivity. Scanning now can be used to pick up thyroid problems; brain tumors and abscesses; liver cancer, cysts, and abscesses; lung clots; bone tumors; kidney tumors, cysts, and abscesses; and many more abnormalities including those of the pancreas, spleen, parathyroid glands, and the heart as well. Judicious use of tests has always distinguished the best physicians. It would be a simple matter, of course, for the physician to just order, indiscriminately, a whole battery of tests-at considerable cost of time and money for the patient.

Rather than this, physicians have been selective, using the patient's case history and their personal examinations as guides, determining, from them what problems if any the patient might be likely to have, and, when justified, using supplementary tests to explore these problems.
