The 4 body fluids are interstitial fluids, saliva, gastric juices and tears.
The list of body fluids in the human body include.
Blood.
Blood plays a major role in the body's defense against infection by carrying waste away from our cells and flushing them out of the body in urine, feces, and sweat.
Saliva.
Semen.
Vaginal fluids.
Mucus.
Urine.
The circulatory system is the part of the body that is responsible for carrying waste out of your body.
Your kidneys filter waste through your blood and then you also urinate waste out of your body through urine.
The human circulatory system is made up of blood vessels that carry blood away from and towards the heart.
Arteries carry blood away from the heart and veins carry blood back to the heart.
The circulatory system carries oxygen, nutrients, and hormones to cells, and removes waste products, like carbon dioxide.
Blood carries waste products to the kidneys via the renal artery.
Inside each kidney, blood is transported to 1.2 million filtering units called nephrons (pronounced NEFF-rons).
The cells in nephrons take in the liquid portion of the blood and filter out impurities (urea, mineral salts, and other toxins).
When cells in the body break down proteins (large molecules that are essential to the structure and functioning of all living cells), they produce wastes such as urea (a chemical compound of carbon, hydrogen, nitrogen, and oxygen).
Other systems and organs in the body also play a part in excretion.
