Best Answer: Interstitial fluid (or tissue fluid, or intercellular fluid) is a solution which bathes and surrounds the cells of multicellular animals. It is the main component of the extracellular fluid, which also includes plasma and transcellular fluid.ot all of the contents of the blood pass into the tissue, which means that tissue fluid and blood are not the same. Red blood cells, platelets and plasma proteins cannot pass through the walls of the capillaries.
While the Kindle Fire has an estimated eight hours of battery life, the original Kindle can be used for over a month without needing a recharge. The backlight in the Kindle Fire requires significantly more memory than the e-ink used in the e-readers, too.
I have had to replace the battery several times through out it's life. It has been 9 years and it still works as well as the day I got it. My kindle has seen heavy use and I push my devices to the limit. The kindle it has held up well and continues to do so to this day so 9 years and counting. The thing about the orginal is you can access the battery where on newer models you can not so they may not last 9 years.
