Chapter 26 3-D Physiology: Nephron Physiology
60 to 70 percent of the fluid in the nephron tubule is excreted as urine. True False
False
Extracellular fluid osmotic pressure is fine-tuned by the presence of absence of antidiuretic hormone which alters the reabsorption of additional water. True False
True
Monitoring the flow of fluid through tubular nephron is accomplished by the juxtaglomerular apparatus monitoring the passage of sodium chloride through the distal nephron. True False
True
Autoregulation of the rate at which fluid passes from the glomerulus into the nephron tubule is through dilation or constriction of the afferent arteriole into the glomerulus. adding or removing sodium chloride in the glomerulus to alter the concentration of the blood. regulation of the diameter of the collecting tubule. altering blood flow to the kidney.
dilation or constriction of the afferent arteriole into the glomerulus
The process by which plasma minus protein passes from the glomerulus into the tubular nephron is by osmsosis. endocytosis. filtration. diffusion.
filtration
The function of the nephron loop is to detoxify and remove wastes. monitor the flow of fluid through the nephron tubule. absorb nutrients in the tubular fluid into the bloodstream. regulate fluid volume and osmolarity.
regulate fluid volume and osmolarity
The kidneys can affect low blood pressure by producing a hormone which results in the constriction of blood vessels and results in the release of aldosterone to increase blood volume. This enzymatic hormone is known as antidiuretic hormone. thyroxin. erythropoietin. renin.
renin
During secondary active transport, the movement of one substance down its electrochemical gradient provides the force to move another substance up its electrochemical gradient. When both substances move in the same direction the mechanism is referred to as a(n) antiporter. importer. symporter. deporter.
symporter
The movement of substances from the nephron tubule back into the bloodstream is referred to as nephron replacement. tubular secretion. nephron recirculation. tubular reabsorption.
tubular reabsorption
The movement of substances from the bloodstream into the tubular nephron is referred to as nephron replacement. nephron recirculation. tubular reabsorption. tubular secretion.
