Osmotic Regulation & The Urinary System
Osmoregulation is the active regulation of the osmotic pressure of an organism's fluids to maintain the homeostasis of the organism's water content.
Osconformers are marine animals which, in contrast to osmoregulators, maintain the osmolarity of their body fluids such that it is always equal to the surrounding seawater.
Osmoregulators are able to control their osmolarity and can adapt to the their surroundings they do this internally.
Amphibians and reptiles regulate their bodies to their environments for example kidneys of marine reptiles tend to act like those of bony marine fish.
Saltwater fish filter out the electrolytes but keep the water they take in vs freshwater fish who keep the electrolytes in but keep the water out.
Unlike humans insects use Malpighian tubules through which uric acid and wastes are secreted but before total excretion water and salts are reabsorbed.
Nephron is the basic structural and functional unit of the kidney. Its chief function is to regulate the concentration of water and soluble substances like sodium salts by filtering the blood, reabsorbing what is needed and excreting the rest as urine.
The vertebrate kidney (this is ours) consists of Blood entering the kidney through the renal artery, and leaves the kidney in the renal vein. The kidney gets about 20% of the blood that is pumped with each heartbeat. Basically the kidney uses its functions to filter the blood of all the wastes and unneeded nutrient resulting in Urine, the blood was first filtered in the glomerous which is inside the bowman’s capsule then the blood exits through the renal vein leaving only the unneeded things, theses unneeded things travel into the loop of Henle this is where the urine is formed, the urine is the final product and exits through the ureter.
Mammals and birds alike excrete concentrated urine but retain water this is very effective and prevents dehydration Excretion of toxins and excess ions maintains homeostasis.
In normal person, almost 440 gallons of blood is passed through the kidneys on a daily basis, thereby resulting in formation of almost one to two liters of urine, but, this amount varies with the amount of fluid intake and the amount of sweat produced by the body.
Urine is considered to be a good therapy by some people, they put it on thier face, body, they even drink it all these techniques are considered to help medically
