Microscope Analysis of Urine
To analyze a urine sample
Examine presence of normal/abnormal elements
Use urine sample to find specific gravity, pH, and chemical parts
To have a better understanding of filtration, reabsorption, and secretion, and see how they affect urine production.
There is a lot of importance that comes with testing urine. Many different diseases can be tested for, (i.e. diabetes) and a urinalysis can provide a lot of useful information to physicians. Simple tests can immediately be taken from simply looking at a urine sample; color, odor, transparency, etc. By looking at the color of urine, things such as hydration levels can be tested. The clearer urine is, the more water that is present. Also, with the use of a microscope, particles like casts and sugar can be detected. The presence of too many certain particles can help to indicate that an infection/disease may be present. There are countless tests that can be taken during a urinalysis that can help to show any abnormalities in the urine and rest of the body.
The process of producing urine and removing toxins from the body occurs in the excretory system. The organs (kidneys, etc.) that are a part of this system are in charge of different aspects of urine production. When urine is being formed, there are three processes that must occur. The first step that occurs is filtration. In this step, diffusion occurs under high pressure because blood is moving to the glomerulus of the nephron through the afferent blood vessel. The lumen size of the vessel becomes immediately smaller, so when substances in the blood are being filtered out, they are pushed through by a high pressure. The kidney at this point is simply trying to maintain a homeostatic control, so not everything is filtered out.
Next, the filtrate goes through reabsorption, which starts to
