Most of the nephron is permeable to urea except for the cortical portion of the distal tubule. As the filtrate descends into the medulla, urea diffuses into the loop of Henle down its concentration gradient, causing the urea concentration in the tubule to rise.he loop of Henle. The loop of Henle is the portion of the kidney that creates the conditions by which the kidney can form concentrated urine (i.e. urine with an osmolality greater than plasma) later on in the nephron.
Battery Voltage : Normally a charged cell in rest is around 2.1 Volts which yields in 12.6 Volts for a charged battery at rest. When the battery is being charged by the car alternator the voltage will vary usually between 14 and 14.4 Volts.
Q: How much does a car battery weigh? How many amp-hours does a car battery contain? A: A car battery's weight depends on the size of the battery, but is typically between 30 and 50 lbs, with most running around 41 lbs (14 kg to 22 kg). Here are some rough estimates of battery weights and Amp Hour capacities of starting, light and ignition (SLI) car batteries. [Home] [PowerStream] [Site Map]
