- "Compared to those of similarly sized birds and lizards, the kidneys of mammals ______." "have larger glomeruli, but shorter nephron loops" have a larger renal cortex but a smaller renal medulla have lower concentration of urea in their renal medulla have higher concentrations of Na+ and Cl- in their renal medullaIn kidney development the _____. nephric tubules develop from anterior to posterior with the metanephric tubules developing last "all of the nephric tubules (pronephric, mesonephric, and metanephric) develop at the same time, beginning just after the somites appear" nephric tubules develop from posterior to anterior with the pronephric tubules developing lastIn humans, the kidneys and urinary system are responsible for removing nitrogenous waste. Turbelarians however do not have kidneys. The part of the turbelarian that is most similar to the human urinary system is; The gastrovascular cavity The metanephridia O The pharynx The coelom
- I know that crustaceans use filiration via the antennal glands for their excretory organ. Is there site of filitration the renal corpuscle just like humansThe inner surface of ____ contains microvilli to increase surface area for absorption. the glomerulus the proximal convoluted tubule the descending and thin ascending limbs of the nephron loop the collecting ductin rat , the bladder is located at the ___ side of the body
- The functional unit of the kidney is called ________. the renal hilus the renal corpuscle the nephron Bowman’s capsuleDuring embryonic development of the kidneys the glomeruli form from the _____. ends of blood vessels branching off the aorta peritoneal funnels of the metanephric tubules somites running alongside the dorsal hollow nerve cord neural crest cells and epidermal placodesIn mammals, the kidneys are the only organs that regulateroutine excretion of water, salts, and nitrogenous wastes fromthe blood. As logical as this may sound to us, it is unique amongvertebrates. For each of the other groups of vertebrates, describethe functions of as many organs as you can—in addition tothe kidneys—that participate in these processes. Consider thediscussions of these groups of animals
