	What is the function of the urinary bladder?     filter the blood   aid defecation   store urine   contain bacteria to fight infection

	The ureter connects which part of the kidney to the bladder?     renal pelvis   renal medulla   urethra   renal cortex

	What is the tuft of capillaries that brings blood to the kidney for filtration?     glomerular capsule   proximal arteriole   Bowman's space   glomerulus

	Most nephrons have short loops and are located almost entirely in the _____________.     renal pelvis   renal cortex   ureters   renal medulla

	What BEST describes the process whereby blood pressure forces water and other dissolved substances from the blood into the glomerular capsule?     tubular reabsorption   tubular secretion   nephritic excretion   glomerular filtration

	What best describes the process that concentrates the urine as it passes the proximal convoluted tubule?     glomerular filtration   tubular secretion   tubular reabsorption   nephritic excretion

	During which of the following processes would dyes or prescription drugs enter the urine?     tubular secretion   glomerular filtration   nephritic excretion   tubular reabsorption

	The kidneys help maintain pH balance by __________.     dissolving the calcium and sodium crystals in the urine   removing bicarbonate ions from the blood   adding soda lime to the filtrate   removing hydrogen ions from the blood

	Which of the following mechanisms are responsible for water conservation in the tubules as they pass through the renal medulla?     increasing concentration of solutes in the interstitial fluid   decreasing concentration of plasma proteins in the interstitial fluid   decreasing concentration of solutes in the interstitial fluid   decreasing concentration of plasma proteins in the interstitial fluid

	Antidiuretic hormone (ADH) _______________.     causes filtration rates to increase   causes the secreting of more sodium ions in the interstitial fluid   changes in the permeability of the nephron tubules   causes the blood to be more dilute

	What structure in the nephron is responsible for monitoring blood pressure?     glomerulus   juxtaglomerular apparatus   proximal convoluted tubule   glomerular capsule

	Which is the correct sequence of events leading to the production and release of aldosterone?     Angiotensinogen is converted to renin which is converted to aldosterone.   Renin is converted directly to aldosterone.   Renin is converted to angiotensin I which is converted to angiotensin II which stimulates the adrenal gland to release aldosterone.   Renin converts angiotensinogen to angiotensin I which is converted to angiotensin II which stimulates the adrenal gland to release aldosterone.

	How are the kidneys related to red blood cell production?     All blood cells are produced in the kidneys.   Precursor red blood cells develop in the renal medulla.   The kidneys are not related to red blood cell production .   Erythropoietin is released by the kidneys.

	What is used as the dialysis membrane in CAPD?     dialysis tubing   the peritoneum   filters in the kidney machine   implanted kidney tubules

	Which of the following would be symptoms of serious kidney problems?     acidosis and build up of nitrogenous wastes in the blood   hypertension and water retention   anemia and edema   all of the above

	Which of the following is true concerning kidney transplants?     There is a shortage of kidneys for transplant.   Removal of the donor kidney is very risky, often fatal.   There is a shortage of people needing kidneys.   There is nearly a 100% success rate using artificial kidneys for transplant.

	Urination is controlled by _______.     hormones   impulses from the prostrate gland   both voluntary and involuntary actions   the internal urethral sphincter

	Why are women more susceptible to urinary tract infections than men?     The urethra combines with the reproductive system in men.   The urethra is shorter in women and the opening is closer to the anus.   The urethra is shorter in men but farther from the anus.   The urethra combines with the vagina in women.
