The kidneys can perform homeostatic functions well as long as at least <em><u>20%</u></em> of the nephron are functioning normally. If nephrons function less, <em><u>uremia</u></em> or a buildup of toxic waste products in the blood can occur.
<h2>Further explanation
</h2>
The kidneys are excretory organs invertebrates that are shaped like peanuts. In adult humans, the kidney is about 11 cm. The kidneys receive blood from a pair of renal arteries, and blood comes out through the renal vein. The kidneys are connected to the ureter, where the ureter carries urine out to the bladder.
As part of the urine system, the kidneys function to filter impurities (especially urea) from the blood and dispose of them together with water in the form of urine.
One part of the kidney is the nephron, the nephron itself is the smallest part of the kidney which is composed of the proximal tubule, distal tubule, and ductal kologentes. It is in this nephron where blood filtering occurs and a very important part of the kidneys which is also part of the human excretion system because it secretes urine.
Functions of nephrons include:
- Blood filtration. This process is also called filtering and is carried out on the glomerulus.
- Reabsorption. The process is re-absorption and is carried out in the proximal consortium Tribulus.
- Excessive secretion of substances or not used by the body. This process is augmentation and is carried out in the distal tubular contour.
- It has the main function in the excretion of urine.
- As a regulator of substances and fluid levels in the body
- Break down red blood cells to produce nitrogen waste.
- Forming urea from protein metabolic waste products
- As a regulator of blood chemical composition.
Uremia itself is a syndrome or a collection of symptoms of serious complications from chronic kidney disease and kidney failure. This can occur when urea levels in the body are high so that it can cause toxins to the body. Uremia occurs because the kidneys cannot function properly. Uremia can be fatal and life-threatening.
