Anatomy questions

anatomy questions????????
The lowest blood concentration of nitrogenous waste occurs in the a. hepatic vein b. inferior vena cave c. renal artery d. renal vein The glomerular cappillaries differ from other capillary networks in the body because they a. have a larger area of anastomosis b. are derived from and drain into arterioles c. are not made of endothelium d. are sites of filtrate formation Glucose is not normally found in the urine because it a. does not pass through the walls of the glomerulus b. is kept in the blood by colloid osmotic pressure c.is reabsorbed by the tubule cells d. is removed by the body cells before the blood reaches the kidney Tubular reabsorption a. of glucose and many other substances is a T-limited active transport process b. of chloride is always linked to the passive transport of Na c. is the movement of substances from the blood into the nephron d. of sodium occurs only in teh proximal tubule Conditions such as diabetes mellitus, starvation, and low-carboyhydrate diets are closely linked to a. ketonuria b.pyuria c. albuminuria d. hematuria

D renal vein: Nitrogen is excreted in the urine so it is filtered out at the kidneys. The renal vein should therefore have the lowest because it is the blood coming back from having the N-waste excreted. B are derived from and drain into arterioles: All other capillary beds begin from arterioles, then progress into venules. These are the only ones that progress into arterioles. C is removed by the tubule cells Removed in the proximal convoluted tubule. Probably A(?): a = I'm not sure what t-limited is b= Water is always linked to Na+, not Cl- c= It's the movement of fluids FROM the nephron back TO the blood, not the other way around. That is describing filtration. d= Sodium is reabsorbed MOSTLY in the proximal tubule, but also in the Loop of Henle, Distal Tubule, and Collecting Duct A Ketonuria: excretion of ketone bodies in the urine
