What are some excretory system facts?

Answer 1

Besides taking out your body's "trash," your kidneys help balance your body's vitamin and mineral levels so your other organs and bones can do their best work. They help in the production of red blood cells and produce a form of vitamin D, which promotes healthy bones. They also keep your blood pressure at a healthy level.

When you feel thirsty, your brain is telling you to get more fluids to keep your body as balanced as possible. If you don't have enough fluids in your body, the brain communicates with the kidneys by sending out a hormone that tells the kidneys to hold on to some fluids. When you drink more, this hormone level goes down, and the kidneys will let go of more fluids.

You might notice that sometimes your urine is darker in color than other times. Remember, urine is made up of water plus the waste that is filtered out of the blood. If you don't take in a lot of fluids or if you're exercising and sweating a lot, your urine has less water in it and it appears darker. If you're drinking lots of fluids, the extra fluid comes out in your urine, and it will be lighter. i copied this from Check out the link for more info!

Answer 2

1. The excretory system is responsible for removing waste products and excess substances from the body.
2. Key organs in the excretory system include the kidneys, which filter blood and produce urine, and the bladder, which stores urine before it is excreted.
3. Other organs that play a role in excretion include the liver, lungs, and skin, which help eliminate waste products through processes like detoxification, respiration, and sweating.
