Answer:
1.Getting rid or the removal of metabolic waste products from the body of an organism is known as excretion
2.the skin excretes sweat through sweat glands throughout the body. The moist, scale-less skin is therefore essential in helping to rid the blood of carbon dioxide, and also allows for urea to be expelled through diffusion when submerged.Nov 29, 2018
3.Excretion gets rid of carbon dioxide, water, and other, possibly harmful, substances from your body. Your lungs excrete carbon dioxide as you breathe out, your kidneys filter out nasties to produce urine, removing nitrogen waste from your body, and your skin sheds excess salt through sweat.
4.Each kidney contains about one million tiny units called nephrons. Each nephron is made up of a very small filter, called a glomerulus, which is attached to a tubule. As blood passes through the nephron, fluid and waste products are filtered out.May 31, 2014
