1.	explain raas cycle ? kidney regulation
Answer» Your body has a huge system involved in the sensation and control of blood pressure, not only within the kidneys, but all over the body - especially in times of great need. This is in contrast to a smaller system called tubuloglomerular feedback, which you can think of as the system that senses and controls blood pressure and glomerular filtration rate within the kidneys on a moment-by-moment basis. When called upon, this smaller system can also rev up the really big system I\'m about to get into. The most important system involved in the regulation of systemic blood pressure, renal blood flow and glomerular filtration rate is called the renin-angiotensin-aldosterone system, or (RAAS) for short.
