The idea of glomerulus is used in anatomy and botany, in both cases to refer to a dense group of certain elements. The glomeruli, therefore, are clusters of certain structures.
In the field of anatomy, the glomeruli are bundles of nerves, glands, or vessels that form tangles. The renal glomeruliFor example, they are networks of capillaries protected by an envelope found in the nephron of the kidney.
The renal glomeruli are responsible for filtering and purifying the plasma from the blood. This concept is also known as blood plasma, and it is the portion of the blood that is in a liquid state and that is acellular, that is, it does not have cells but only extracellular matrix. The plasma of the blood is that part in which there are no red or white blood cells, and in its composition we find 90% water, 7% proteins and a mixture of glucose, fat, hormones, vitamins, nitrogen, carbon dioxide. carbon and oxygen in the remaining 3%.
This task of filtration and purification takes place within the framework of the urine production process, since the waste becomes part of this liquid, while the useful materials are reabsorbed.
It is known as glomerular filtration rate or rate to the number of milliliters of fluid that the capillaries of the renal glomerulus filter into the sinus of Bowman’s capsule in one minute. The data serves as a reference for kidney function: if the values glomerular filtration rate are abnormal, it may be due to kidney failure.
The first known description of the glomeruli dates from the year 1666, and was made Marcello malpighi, an anatomist born in Italy. Just a century and a half later, a surgeon named William bowman carried out a more in-depth observation, including mentioning the continuity of the proximal tubule and its surrounding capsule.
It is called glomerulonephritis to a disorder that alters the structure and function of the renal glomerulus. The causes of this disease that affects the filtration of wastes from the blood are diverse.
In general, glomerular diseases, a group in which glomerulonephritis is framed, cause various types of damage to the glomeruli and generate a loss of red blood cells and proteins through the urine. In some cases, these health problems lead to a build-up of waste and Water that can be seen externally in the ankles, hands or face, in the form of swelling.
In this sense, many people who are aware of these risks wonder how we can realize that a glomerular disease has attacked us. One of the most worrying things is that it is possible not to present a single symptom over several years, and for this reason it is very important to pay attention to certain signs that sometimes go unnoticed, such as the following: foamy urine, dark or pink in color; swollen hands and ankles, especially at the end of the day; inflammation around the eyes in the morning.
To find out if the levels of red blood cells and protein are normal, a analysis urine. Similarly, a blood test can reveal whether too much debris has been concentrated.
The olfactory glomeruliOn the other hand, they are structures found in the olfactory bulb (a structure of the brain). These glomeruli are surrounded by neurons and cells glial.
In the field of botany, the glomeruli are inflorescences composed of flowers that lack a peduncle. These inflorescences have a globular and contracted shape.
