describe the waste remove from our body
Answers
You remove waste as a gas (carbon dioxide), as a liquid (urine and sweat), and as a solid. Excretion is the process of removing wastes and excess water from the body. Recall that carbon dioxide travels through the blood and is transferred to the lungs where it is exhaled. ... Therefore, your urine gets darker than usual.
Body Waste: Urine
kidney
Your body is 60% water. This water needs to be flushed out and replaced all of the time. In your body, the excretory system helps to keep salts and urea from building up to dangerous levels and becoming toxic. The kidneys are two bean-shaped organs that remove these toxins from your blood and produce urine to carry them from the body.
This waste then trickles down the ureters — thin tubes that connect the kidneys to the bladder. Your bladder is a container for your urine that holds it there until you are ready to go to the bathroom. When you are ready to get rid of this waste, your body relaxes a small muscle and the urine travels down the urethra — another small tube — and out of your body. Drinking lots of water will help this system of your body to stay healthy and to work properly. The kidneys of a healthy adult can process fifteen liters of water a day.
Body Waste: Carbon Dioxide
Lung
Breathing is the job of the lungs. We take air into our body when we inhale. But air is made of a variety of gases such as nitrogen, oxygen, argon, and carbon dioxide. We need oxygen, but we can not use the other gases. Dust and pollutants are also a part of the air we breathe. Our nose and throat help to filter out some of these particles so that they never make it to our lungs.
Our cells make carbon dioxide as a waste product from the process of converting food to energy. That carbon dioxide — and some water vapor — are removed by the lungs when we breathe and exhale them back into the atmosphere.
Body waste: Excrement
Digestive System
When we eat, our body begins to digest the food matter in our mouth. First we grind the food with our teeth, and then our saliva helps to dissolve certain parts of it. When we swallow, the food moves into our stomach where additional chemicals are added, and the food is turned into a sort of liquid like a milk shake called chyme (pronounced kime).
This liquid passes into the small intestine, where the body adds special juices to digest fats and neutralize some of the acids that were created in the stomach. In the small intestine, a special hair-like lining known as villi absorb the liquid parts. Those liquid parts — the nutrients — pass directly into the blood and are taken to all your cells throughout your body. These nutrients feed your cells the food they need.
Any left over solid parts of the food move into the large intestine. These solid parts of your food are the parts that you have no use for and are passed from your body when you go to the bathroom. The scientific word for this matter is excrement or feces. You probably call it poop. The entire trip from mouth to rectum can take about 24 hours in the average person.
Body waste: Earwax
Ear
Our ear canal is a tunnel to the outside world. Dirt and grime can get into this passage. So our bodies have a way to capture this unwanted material. Earwax does the trick. It is a sticky product called cerumen that is created by a gland just inside the ear.

Cerumen keeps the skin of the ear canal moist and prevents infections. Sometimes this earwax leaves the body. This helps remove the unwanted dirt and germs.
Never stick your finger or other objects inside your ear. Leave it alone and let your body do its own work. It is possible to push the wax further into the canal, injure your eardrum, or scratch the ear canal.
Body waste: Nasal Discharge
Blowing Nose
Your nose is also a path for the germs and dust that can enter your body. Nasal discharge (snot) is a way for your body to remove unwanted debris. Sometimes you sneeze or blow your nose to help your body with this job.
If you see dirt in your nasal discharge, you do not need to worry. On rare occasions, you might even find an eyelash. Still no worries. This is very normal. If your nasal discharge is an unusual color such as green you should see your doctor, as this may be a sign of an infection.
Body waste: Tears
Cry
Tears are another way for your body to clean unwanted things from your body. Dirt and other objects can get into your eye, especially when the wind blows.
Your eyes naturally create tears to keep your eyes moist and to remove other matter that could irritate your eyeballs. Even smells like onion juice can bring on the tears.
Body waste: Sweat
Sweat
When your body gets too hot — and even sometimes when you get nervous — your body can sweat. The hypothalamus is a part of the brain that regulates your body temperature. When the hypothalamus gives the signal, the sweat glands in your skin begin to make sweat.
Sweat is also called perspiration and is made from waste in your body. Sweat contains urea, salts, sugars, and ammonia. It moves from the sweat glands onto the surface of your skin, and as the air moves across your skin the sweat evaporates and cools off your body. If you sweat a lot, you will need to make sure to replace the moisture that evaporates from your skin by drinking lots of water, especially on a really hot day.
