6. What is glomerular filtration and what factors effect it

1) Compared to those of similarly sized birds and lizards, the kidneys of mammals ______. A) have larger glomeruli, but shorter nephron loops B) have larger glomeruli, but shorter nephron loops C) have lower concentration of urea in their renal medulla D) have higher concentrations of Na+ and Cl- in their renal medulla

List the 4 processes typically used by excretory systems and briefly explain each process

What are three disorders of the excretory system? and What are the organs of the excretory system?

1. What would be the influence of decreasing reabsorption of sodium on urine volume?

1.What is the role of the renal system in regulating potassium ion concentration in the extracellular fluid [ECF]? a. Kidneys filter and excrete excess potassium ions into the urine. b. Kidneys respond to aldosterone by not excreting any potassium ions into the urine. c. Kidneys reabsorb all potassium ions into the urine. d. Kidneys excrete water molecules through aquaporins in the collecting duct.   2.Identify the cardiac dysrhythmia most associated with hypomagnesemia.
