3 Stages:  + Filtration: Glomerulus/Bowman’s capsule  + Reabsorption: Proximal tubules (60%)  + Secretion: Distal tubules    Goals: Removes waste, save goodies, conserve water    Nephron Diagram          1. Filtration: blood is being filtered in glomerulus, pushing GF material into Bowman’s  capsule where it’s collected   2. Reabsorption: 60% of reabsorption occurs in proximal tube, Active Transport (ATP  spent) to force GF material out, reabsorption occurs along entire length of tubule   3. Secretion: occurs in distal tubule, also uses Active Transport, goes into collecting duct  which drains down to the renal cavity trying to conserve water    ❏ Vertebrate Nephron Differences  Freshwater Fish               ​ altwater Fish  ­Environment H2O Higher Concentration ion     ­Environment H2O Lower Concentration  ­Body H2O Lower Concentration       ­Body H2O Higher Concentration  ­Constant intake of water     ­Constant loss of water  ­Get enough water by osmosis therefore            ­Drinks saltwater regularly  do not drink water                                               ­Stores ions in tissues (urea)  ­Large Glomerulus     ­Small Glomerulus  ­Short tubule: don’t want to reabsorb                 ­Long Tubule to reabsorb water  water want to get rid                                           ­Concentrated waste not diluted with water  ­Diluted waste, ammonia       Mammals:  +Loop of Henle: constricted portion of tubule (loop) slows down  Glomerular Filtrate (GF) moving through tubule  ­ Allowing for more water to be reabsorbed  ­ Allowing for more goodies to be reabsorbed   ­ Allowing more concentration secretion of wastes into tubule   ­ Wastes become 20X more concentrated  +Plan of this is to minimize loss of water, goodies, and increasing  concentration of waste (urea)    Endocrine System Ch. 50  Fig. 50.1  Table 50.1, 50.2  Endocrine in charge of Hormonal Control of Bodily Function    +Hormones:  ­Signaling type of molecules such as Neurotransmitters (nervous system) and Pheromones  ­Hormones are transported via blood stream and have a specific target cell  ­Endocrine Glands are ductless secrete hormones directly into bloodstream to be distributed to  body  ­Exocrine glands have ducts such as sweat to surface of skin    +Few Vertebrate endocrine glands + Associated Hormones  1.
