Relate the functions of the kidney to it's excretory & osmoregulatory function?

Question

to answer this question you must ask yourself what are the organs invovled in the excretory system. and is the kidney suited to it's function. Are the parts of the kidney all playing a role and what is that role???

Answer 1

Simple version: Basic unit of the Kidney is the nephron. the nephron meets up with the blood supply at the glomerulus. fluid and solute are filtered by pressure into the nephron from the blood. Certain molecules are not filtered (large charged particles in particular - like protein). Increase the amount of fluid (free water) in the body, and the pressure increases, filtering out more water, regulating the osmolality of the serum. Also, the main way to rid the body of waste like urea, is to excrete it in water. the nephron has various segment wich vary in the permeability to various molecules. It sets up an osmotic gradient which allows the waste to remain in the nephron, while water and important molecules like glucose and sodium are resorbed. For ALL the parts and ALL the roles, you need to look at a medical basic science text book.

My Doctor Told Me the depressing news - "Your Kidneys Are FAILING!"

My worsening kidney disease symptoms included:
- Nausea and vomiting and constant stomach upset
- Passing only small amounts of urine and stopping and starting while urinating
- Swelling in my ankles and lower legs
- Puffiness around my eyes with brain fog and moodiness
- Chronic fatigue and shortness of breath when exerting myself
- Loss of appetite and not wanting to eat at all
- Increasingly higher blood pressure
- Bouts of anxiety and depression
- Muscle cramps which were worse in my legs

That a friend of mine sent me a link to a website (http://NatureHomeCure.com) that helped his Mother. She was just like me, and was suffering with failing kidneys and experienced the same worries and fears I was going through. All I could do was try it and see if it worked.

Here's where the story gets a little strange. Two months later, Instead of my kidneys sliding down the slippery slope of kidney failure and getting progressively worse, they started to get better.

My Doctor could not believe how much improved my kidney function output had increased and my GFR was UP and creatinine levels lower. My kidneys were starting to work again, and removing all the toxins in my body. I got my life back!

Now, I am using this 100% all natural protocol which restored my kidney function and did it naturally, without the use of unnatural man-made pharmaceutical drugs or dialysis. In less than two months my kidneys were on the mend. Now six months later, My kidney's are back to normal again.
