Glomerular Filtration
Glomerular filtration precedes the generation of urine. It is the process through which your kidneys filter surplus fluid and waste from your blood into the kidney’s urine-collecting tubules, enabling your body to dispose of them.
Why we make urine?
Most people don’t give much thought to the process of urinating unless something goes wrong, but your kidneys and urinary system are actually very impressive. Together, they receive more than a liter of blood every minute and excrete around 1.5 liters of urine each day, effectively eliminating extra water and waste that would otherwise cause you major difficulties.
Your body metabolizes (processes) the food and liquids you consume to create energy as well as the many building blocks required to maintain the health of your tissues and organs. As a result, numerous more compounds are created, many of which must be removed to avoid hazardous buildup because they cannot be used immediately or stored for later. In addition to waste products, our diets frequently include compounds in quantities substantially greater than what we require on a daily basis (such as carbohydrates and fats). You eliminate both water-soluble and non-water-soluble waste materials in your urine and feces, such as bacteria and undigested fiber (e.g., urea and electrolytes – sodium and potassium). Beets, blackberries, and rhubarb, for example, can turn urine red or pink. Certain foods and medications can also alter the color of your urine. This is proof that the vibrant soluble pigments are being excreted from your body through your kidneys.
Urine primarily excretes the following substances:
- Metabolic byproducts, such as urea and creatinine
- Your body employs electrolytes, which are inorganic substances such as sodium, potassium, calcium, chloride, and bicarbonate, to regulate the fluid content of your body fluids.
- Water
Glomerular Filtration
The kidneys are two reddish-brown, bean-shaped organs found in vertebrates. They are located on the left and right sides of the retroperitoneal space in adults and are about 12 centimeters long. They have paired renal arteries and veins that carry blood into and out of them. Each kidney has a ureter, a tube that carries urine from the kidneys to the bladder.
The kidney takes involved in the regulation of toxin elimination, fluid osmolality, acid-base balance, various electrolyte concentrations, and volume of various body fluids. One-fifth of the blood volume that enters the kidneys is filtered in the glomerulus, where filtering takes place. Amino acids, salt, bicarbonate, glucose, and solute-free water are a few examples of compounds that are reabsorbed. Hydrogen, ammonium, potassium, and uric acid are a few examples of chemicals that are released. The structural and operational unit of the kidney is the nephron. A mouse kidney only has about 12,500 nephrons, compared to the roughly 1 million seen in an adult human kidney. Additionally, the kidneys perform tasks that are not dependent on the nephrons. For instance, they produce the hormones erythropoietin and renin, as well as the conversion of a precursor of vitamin D into its active form, calcitriol.
