  • The Role of the Nephron - 1996 Words
    The Roles of the Nephron of the 120 ml of blood that is filtered by the kidneys each minute, only I ml (that's less than I%) turns into urine that will eventually leave the body (after approximately 300 - 400 mis of it accumulates to fill the bladder!) That leaves 119 ml of fluid called filtrate to be returned back to the blood stream. Good thing, otherwise you would have to micturate (pee, urinate) once every 3 minutes and drink 1 L of fluid every 10 minutes in order to maintain Homeostasis!!!...

    As long as you are alive, your body will constantly metabolize organic molecules and produce waste products. If you can not get rid of these metabolic waste products, they will accumulate to toxic levels and poison your body. The urinary system is very important because it perform the essential function of getting rid of these metabolic wastes. Main Structures of the Urinary System The main structures that make up the urinary system are two kidneys (contains nephrons), two ureters, one bladder,...

    Blood Water Homeostasis or Osmoregulation Osmoregulation is the process by which the body regulated the osmotic pressure of any organism’s fluids in order to keep the homeostasis of the organisms’ water level constant. Therefore osmoregulation is used to keep the bodily fluid from being too diluted or too concentrated. An osmotic pressure is used to measure the ability of water to move from one solution to another solution through osmosis. Osmotic pressure refers to tendency for a liquid...

  • The kidney's structure, functions, and what controls these functions.
    The kidney is made up of nephrons, which are a kidney's functional units. These nephrons collect fluid filtered from the blood. The kidney connects to the renal artery, renal, vein, and ureter. 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...

    Abstract: The experiment was done to demonstrate the effect of ADH on the volume and concentration of urine in order to demonstrate the control of ADH over blood plasma osmolarity. Since non-invasive methods were preferred the volume and concentration of urine was used in place of drawing blood. The results that we our anticipating are that ADH levels in the group of subjects that ingested the 6 gm. Of NaCl would increase over time in response to the increased osmolarity of the blood from...
