Urine
Urination is the release of urine, or liquid waste, from the kidneys. If you are male, your urine comes out of the penis; if you are female, you have a separate urinary opening - both of these are called the urethra.
They filter the blood (actually just the plasma, the watery part of blood). All kinds of stuff are filtered out (glomerulus) and then all the good stuff is reabsorbed (proximal tubules) ... its a throw out the baby with the bathwater, but then catch the baby sort of trick.
Unlike most other mammals, birds do not urinate seperately from their feces. Their kidneys extract the wastes from their blood stream and it is excreted as a white paste. It is the same type of uric acid that is mostly prevalent in our watery urine, just appears white when excreted in this manner.
The watery fluid inside the uterus during pregnancy is called amniotic fluid and it is surrounded by the amniotic sac. The fluid is a protective shock absorber but it also contains proteins, lipids, carbohydrates and phospholipids which help aid in the development of the growing fetus.
Sebaceous glands secrete oil to protect the skin. Sweat glands secrete watery perspiration to excrete wastes and cool the body.
The excretory system works when you eat food and the bad substances form your food is carried to your kidneys. Then the nephrons purify the blood and the bad watery stuff goes down the ureter and then goes to the bladder. Then, once the bladder is almost filled, the urea goes down the urethra and outside of your body.
