Purified blood leaves the kidney using the renal vein‚ urine leaves using a ureter and the renal artery carries blood from the aorta to the kidney. The nephron has a cup-shaped nephric capsule that surrounds a cluster of capillaries called the glomerulus. A good deal of fluid from the blood filters into the capsule. Large proteins and whole blood cells are left behind due to the fact that their too big to pass through the filters along with the plasma or blood fluid. There are four main parts of

Once again my mini-sub and I will be miniaturized (8 microns long) and witnessing another ‘Fantastic Voyage’ in a human body. This time I will be swallowed by George‚ a 55 years old man‚ while he is eating his meal consisting of a hamburger‚ French fries and a soda. I will pilot my mini-sub through George’s GI (gastrointestinal tract)‚ which is the tube that starts with the mouth and proceeds to the esophagus‚ stomach

removal possible. (EmedicineHealth‚ 2012) One kidney has about a million nephrons‚ meaning a person has two million nephrons in total. In each nephron‚ has a tiny blood vessel called the glomerulus or the capillary intertwines that is connected to a tiny urine-collecting tube also known as the tubule. The glomerulus is what filters the waste‚ and the proteins. While the waste is being processed‚ a chemical reaction takes place as the waste materials and water leave the blood to enter the urinary system

protein levels‚ high cholesterol levels‚ and swelling. The urine may also contain fat‚ which can be seen under the microscope. Nephrotic syndrome is caused by various disorders that damage the kidneys‚ especially the basement membrane of the glomerulus. This causes abnormal excretion of protein in the urine. This condition can also occur as a result of infection‚ use of certain drugs‚ cancer‚ genetic disorders‚ immune disorders‚ or diseases that affect multiple body systems including diabetes
