external sphincter muscle of the bladder

Urine is formed by the nephron by means of which three processes? Filtration, secretion, and excretion Filtration, reabsorption, and excretion Filtration, reabsorption, and secretion Reabsorption, secretion, and excretion

filtration, reabsorption, and secretion

Effective filtration pressure (EFP) is determined by comparing the forces that push fluid into the capillary with those that push: fluid out of the capillary. fluid back to the glomerulus. urine into the bladder. none of the above.

fluid out of the capillary

The capillary network that is fitted neatly into Bowman's capsule is the: nephron. renal corpuscle. proximal convoluted tubule. glomerulus.

glomerus

kidney stones

The branch of the abdominal aorta that brings blood into each kidney is the: renal vein. renal artery. arcuate artery. interlobular artery.

renal artery

_____ has a central role in the regulation of urine volume. ADH Aldosterone TSH Plasma

ADH

Urine is approximately 95%: nitrogenous wastes. electrolytes. water. hormones.

water
