Background: Henrik is building a terrace with a wooden trolley and uses a powerful cutting / miter saw. He has just been peeing in the woods when he starts sawing. His son plays football next door. The son gets a foul and shoots Henrik in the head !! He stumbles and the accident occurs. The hand comes against the saw blade and tears off 2 fingers !!! He bleeds heavily, and loses at least 1L of blood before the ambulance arrives. When the ambulance staff is on site, they take their blood pressure and see that it is very low and they go to the hospital very quickly. Once inside the hospital, he gets a catheter and he sees that there was some urine in the bladder. Since Henrik teaches about kidney function, he immediately begins to think about what he read about the kidney's reaction to greatly reduced blood volume as a result of ex. an injury. Describe step by step the following: a) the kidney's reaction (from the afferent blood vessels into Bowman's capsule to the bladder) to the given circumstances. b) which regulatory hormones are important and via which mechanisms do they work? c) What is the concentration and volume of urine that he has seen formed?
