Anatomy and Physiology of Urinary System
The major function of the urinary system is the removal of metabolic
wastes, which is basically what urine contains. Solid waste would
naturally be in the faecal matter, which is a product of the digestive
system. However, the duties of the urinary system go beyond simply
producing urine and eliminating it. The main job of the blood filter is
to remove metabolic waste from your body fluids, but it also controls
blood volume and blood pressure in addition to filtering blood. Two
kidneys are located on either side of the spine, between the thoracic
vertebrae at the base of the thoracic curvature (vertebrae 12), down to
roughly the third lumbar vertebra. The surrounding connective tissue
holds the left kidney in place, which is somewhat superior and
slightly higher than the right kidney. It's amazing to consider that in a
healthy person, over one litre of blood passes through the kidneys
every minute of your life. The average person has roughly five litres,
or ten pints, of blood in their body. The term "renal" refers to the
kidneys only.
A glomerulus is a collection of capillaries that enters a tiny capsule.
The capsule's inside is then filled with various substances, such as
water ions, which eventually give rise to tiny tubes and tubules. Each
kidney has 1.25 million nephrons, and 2.50 million of these tiny,
miraculous filters are at work. Things that are small enough to fit
through fenestrated capillaries can pass through them very easily and
fast. Although the water and solutes passing through this tube will
eventually become urine, at this stage you can suction out some of the
nutrients, ions, water, and plasma proteins that happen to pass through
due to osmosis and diffusion. Then you reach what is referred to as
the collecting system after some last filtering, secretion, and
reabsorption. This purple area is the collecting duct, which carries
concentrated urine and combines with the papillary ducts. The
collecting system gathers all the various collections you're in from the
