Answer:
What is glomerular filtration?
Unless things go wrong, most of us don’t spend much time thinking about what it takes to urinate, but in fact, your kidneys and urinary system are quite amazing. Together they receive over a liter of blood each minute, and eliminate around 1.5 litres of urine per day, efficiently getting rid of excess water and waste products that would otherwise cause you some serious problems.
Glomerular filtration is the first step in making urine. It is the process that your kidneys use to filter excess fluid and waste products out of the blood into the urine collecting tubules of the kidney, so they may be eliminated from your body.
Why we make urine
Your body metabolizes (processes) the things you eat and drink, which produces energy, as well as the various building blocks that you need to keep your tissues and organs healthy. While doing this, a variety of other substances are produced that can’t be used or stored for later, and must be eliminated to prevent toxic build-up. In addition to waste products, our diets often contain substances in amounts that are far more than we need on a day-to-day basis (such as carbohydrates and fats). You get rid of non water-soluble waste products in feces (e.g., undigested fibre and bacteria), and water-soluble waste products in urine (e.g., urea and electrolytes - sodium and potassium). Some foods and medications can change the colour of your urine; e.g., beets, blackberries and rhubarb can turn urine red or pink. This is evidence that your kidneys are eliminating the colourful soluble pigments from your body.
The main substances excreted in urine are:
metabolic waste products - e.g., urea and creatinine
electrolytes - inorganic compounds (including sodium, potassium, calcium, chloride and bicarbonate) that your body uses to control the fluid content inside your body fluids.
water
You can think of your kidneys as being your body’s natural blood filter. They are able to control the amount of water and substances dissolved in your body fluids (solutes) by reabsorbing what you need and producing urine to get rid of the rest. The production of urine is obligatory, meaning that it is made regardless of what is going on with your body; for example, you still make urine even when you are severely dehydrated. This occurs because of the need to remove various solutes from the body in order to keep internal conditions stable and relatively constant (homeostasis), so that your all of your body’s physiological processes continue operating effectively. Making urine is a complicated process, and to do it, each of your kidneys contain around a million specialized structures, called nephrons.
