Which row below indicates a mismatch between the processes and the functions of the kidney?
Process: excretion of metabolic wastes
Function: rids the body of urea and uric acid
Process: maintaining the water-salt balance
Function: helps regulate blood volume
Process: maintaining the acid-base balance
Function: rids the body of nitrogenous wastes
Process: regulating salt balance in the blood
Function: reabsorption of various ions including Na+
Most of the nephron's cells contain a large amount of mitochondria, especially the proximal tubule, ascending loop of Henle and distal tubule. The reason is that these cells perform which of the following functions?
filtration
diffusion
osmosis
active transport
In a healthy person, red blood cells, platelets and plasma proteins are
absent in filtrate and urine
present in filtrate and urine
absent in filtrate and present in urine
absent in urine and present in filtrate

distal tubule
glomerular capsule
proximal tubule
loop of Henle
The high level of Na+ ions in the tissues of the renal medulla is primarily the result of active transport of Na+ ions out of which of the following?

The two components listed above that are completely reabsorbed from the glomerular filtrate before it becomes urine are
urea and uric acid.
proteins and amino acids.
glucose and amino acids.
urea and glucose.
Which of the following statements is CORRECT?
Glucose is the only component of the filtrate to be completely reabsorbed and returned to the cardiovascular system.
Uric acid is the most abundant component found in the urine.
Glomerular filtrate can be described as plasma without the proteins.
Most of the urea found in the filtrate is reabsorbed and returned to the cardiovascular system.
During which process is waste, excess salts and toxins actively transported from the renal capillaries into the nephron to form urine.
Filtration
Reabsorption
Secretion
Active transport
In a healthy person, the main job of the kidney is to produce urine that contains
indigestible foods and bacteria.
glucose and amino acids.
toxic waste products of metabolism.
water and plasma proteins.
